One was agroforestry system (AF) with citrus trees (Citrus reticulata) intercropped with peanut crops (Arachis hypogaea L.) in a downslope alley and another was monocropping of peanut system (MC) located in parallel to AF. They have a slightly soapy, slippery texture, and do not clump easily; If soil froths when placed in a jar of vinegar, then it contains free calcium carbonate (chalk) or limestone and is lime rich. Crops such as pulses, rice, sugarcane, and cotton are produced on this soil. A few research farmers pointed out that it was easier to till the land after lime application. Interestingly, the production of potato increased by about 50% in plots where lime was applied. Y. Wang, B. Zhang, in Advances in Agronomy, 2017. Red soil contains a high percentage of iron content, which is responsible for its color. Desert soils occupy large areas in the arid parts of western and northwestern India, lying between the river Indus and the Aravalli mountain range. The soil is rich in iron, lime, calcium, potash, magnesium, and aluminium. The trees and crops were planted in rows down the slope, which was about 6% in gradient and 130–150 m long. Rocks and dust with a color red due to the iron within the structure of the minerals in the soil. The mean free adsorption energies to the red soil particles are presented in Fig. The small letters for soil horizons are: t, accumulation of silicate clay and v, plinthite. These are generally poor in nitrogen, phosphorus and humus but rich in iron, aluminum and calcium. The colour can be darker due to organic matter. Soil samples were taken by soil horizon for physical and chemical analysis. Photo about It is a red soil rich in iron. 3.15 that mean free adsorption energies of divalent cations at field strengths beyond 100 kV cm− 1 were distinctly larger than those of monovalent cations—the adsorption energies of the two valence groups diverged as field strengths increased. The results show that there is a slight increase in soil pH (by 0.1–0.3) after one crop season following lime application. In goat kids, copper deficiency is expressed mainly as the delayed form with lesions of cerebellar degeneration. Plants growing in sandy soils have higher leaf oil yield and citral content. But in the lower areas they are rich, deep dark and fertile. The increase in release rate of aluminum along with faster silicon release rates, owing to faster dissolution rates of augite and labradorite, brings about kaolinite saturation in the water and precipitation of kaolinite. In Nepal very few studies have been carried out on the remediation of toxic substances from the soil. Nepstad et al. Eight sites with low soil pH were selected. The peanut crops were sown horizontally along the slope at a spacing of 0.2 × 0.3 m2 in rows in both systems. Another important aspect of soil type, is the pH (acidity or alkalinity). They display bilaterally-symmetrical malacia (softening) of the cerebral white matter and defective myelinogenesis, leading to cerebral cavitation. Can you explain this answer? The iron compounds in these soils are in a hydrated form and therefore do not produce the 'rusty' colour. Apart from being the largest Defence community, EduRev has the largest solved For example: 120, 230 and 294 kg of lime per ropani on clay loam were used with soil pH of 6.0, 5.5 and 5.2, respectively. Clays include the kaolinite of red ultisol and are usually made up of complex silicate minerals. In this paper, we reviewed recent publications on iron redox cycling and its coupling to the fate of heavy metals and metalloids. Red soil, Any of a group of soils that develop in a warm, temperate, moist climate under deciduous or mixed forests and that have thin organic and organic-mineral layers overlying a yellowish-brown leached layer resting on an illuvial ( see illuviation) red layer. Although C. flexuosus flourishes in well drained sandy loams in India, it is grown in almost all types of land available from very light sandy soil to upland laterites. Red soil is an important soil resource, which bears substantial implication for sustainable development of agriculture and healthy growth of economy. Soil organic carbon was measured after wet digestion with K2Cr2O7–H2SO4 (Kalembasa and Jenkinson, 1973). This soil shares 15 % of all types of soil in India. This soil can form from iron-rich sediments or the compounds may develop in the soil as it weathers. This is referred to as the northeast monsoon period. Peter Windsor, in Veterinary Reproduction and Obstetrics (Tenth Edition), 2019. In sandy loam and red soils, it requires good manuring. They also contain potash. By and large, the red soils are poor in lime, magnesia, phosphates, nitrogen, and humus, but are rich in potash. The term “terra rossa” comes from the Italian for “red soil” or “red earth”. are solved by group of students and teacher of Defence, which is also the largest student The effect of lime on soil pH and production demands much more intensive scientific study including cost–benefit analysis, proper design, and accuracy of measurement. Table 1. You can use this soil in your garden provided you mix some other nutrient rich soil in order to make up for the loss. Plant roots can be deprived of oxygen from water-laden clay soils. These minerals create the color in clay. There are a number of different kinds of soil that is red, and simply identifying the color does not provide very much information about it other than a verification that it is probably high in iron. the areas served by the rivers Indus and Ganges), and occupy 800 000 km2). The effect of the biota on weathering rate may be due to the release of organic acids and the complexing of aluminum in solution, thus increasing the apparent solubility of aluminum and indirectly increasing the dissolution rate of gibbsite, which is dissolving. Is red soil rich in humus? Lemongrass flourishes in a wide variety of soil ranging from rich loam to poor laterite. A recommended dose of lime was applied to five ropanis of land (1 ropani = 508 m2) by each of three farmers (three sites) in Lamdihi to test its effects on maize. In India, the highest herb and oil yields per hectare of C. flexuosus are obtained in soils of pH 7.5. Initially the rate of acidification was higher in the non-red soils than the red soils but acidification was significant in both soils in the second year. Because this study aimed to differentiate the agricultural land-use effects on lateral and vertical soil hydrological pathways, two cropping systems were compared on the same slope. The biota consists of pasture, secondary forest, and crops, and there is some anthropogenic effect. Soil particle size distribution was measured with the pipette method (Lu, 1999). Alka Dwevedi, ... Arvind M. Kayastha, in New Pesticides and Soil Sensors, 2017. community of Defence. Nov 19,2020 - Red soil is rich in which of these?a)Limeb)Ironc)Magnesiad)Aluminae)All of the aboveCorrect answer is option 'B'. The tree root density in a 0.5 × 0.5 m2 area was counted and soil samples were taken for physical analysis at each soil horizon. It is formed by the weathering of ancient crystalline and metamorphic rocks, particularly acid granites and gneisses, quartzitic rocks, and felspathic rocks. By continuing you agree to the use of cookies. Some investigations have been carried out on the effect of pine litter in compost to soil acidification on red soils originating from phyllitic parent materials and brown (non-red) soils from quartzitic materials. The peanut crops in AF were planted in 1.5-m-wide strips between the citrus trees, and all the field management practices were identical for the peanut crops. Soils of pH 5.5 to 7.5 are utilized. The soils of India have been broadly classified into as many as 25 different types, but in this brief survey we are concerned with the five most widespread, which are: Red soils which occupy 500 000 km2, lying chiefly in the southern, eastern and northeastern parts of the country. The pH is generally neutral to alkaline. Red soil is soil that has a reddish tinge as a result of the presence of iron compounds in it. Question 4.1: Explain the formation of a chemical bond. (ii) Soil is formed by the deposition of sediments brought down by the rivers. Correct answer is option 'B'. Black soil in India is rich in metals such as Iron, Magnesium and Aluminum. This discussion on Red soil is rich in which of these?a)Limeb)Ironc)Magnesiad)Aluminae)All of the aboveCorrect answer is option 'B'. The most exciting findings on the iron biogeochemistry processes include dissimilatory iron reduction, Fe(II) oxidation, and Fe2+-catalyzed recrystallization of iron (hydro)oxides, all of which contribute to the immobilization of heavy metals. As distinct from red soils, these are generally much deeper and contain a fair percentage of limestone and carbonates, resulting in a high pH of 8.5–9. In pot trials C. flexuosus grown in soils with electrical conductivity of 11.5,10 and 5.5 mmhos/cm showed no significant reduction in herb and oil yield and the citral content was unaffected by increasing salinity levels up to 15 mmhos/cm (Weiss, 1997). Chemically, red soil is siliceous and aluminous, with free quartz as sand, but is rich in potassium, ranging from sand to clay with the majority being loamy. Question bank for Defence. Yu-Jun Wang, ... Shmulik P. Friedman, in Advances in Agronomy, 2013. The soils developed from Quaternary clay are classified as a loam clay Ultisol according to the USDA soil taxonomy (Soil Survey Staff, 2010). The most distinctive characteristic of an iron-rich soil is a ruddy orange or red color, though not all red soils are rich in iron. is done on EduRev Study Group by Defence Students. agree to the. There are two reasons for this: (1) fertile (rich) soil had been brought down from Canada by the glaciers; and (2) a great deal of organic matter had been left from Lake Agassiz. The citrus trees were spaced at 4 × 4 m2 along the slope and peanut crops were sown in a 1.5 m wide alley between the tree rows. Red soil is rich in iron and potash and is found in the eastern and southern parts of the Deccan plateau, Chhattisgarh, Orissa, and southern parts of middle Ganga Plain. Answer. However it is deficient in Nitrogen, Potassium, Phosphorous and Humus. Can you explain this answer? While the carbon and calcium content improved with pine litter addition, the pH decreased. As mentioned in Section 5.3.1, for pH values of the tested suspensions ranging from 5.6 to 7.1, the positive charge carried by the red soil particles was only 1.1–5.5% of its negative charge (Fig. This soil is deficient in nitrogen, humus, phosphoric acid, magnesium, and lime but fairly rich in potash, with its pH ranging from neutral to acidic. When the iron deposits in the soil oxidize, they turn a distinctive rust color that tints the soil red. The elevation at the catchment ranges from 41 to 55 m above the sea level and the soil depth ranges from 0.4 to 2.0 m. The upland soils were developed from Quaternary clay and are classified as loam clay Ultisols according to the Soil Taxonomy (Soil Survey Staff, 2010). Alluvial soils (including calcareous, saline, alkaline and coastal soils) occur mainly in the southern, northwestern and northeastern parts, and, most importantly, in the Indo–Gangetic Plain (i.e. The potential teratogenic effects of these copper-accumulating situations is worthy of more detailed investigation. This soil is rich in iron, magnesia and alumina, but does not have phosphorous, nitrogen and organic matter. (iii) It is found mainly in Northern plains and coastal plains of India. (i) It is the most important and most fertile soil found in India. The first is the mountain range called the Western Ghats, stretching for about 800 km along the western coast along the Arabian Sea. Answer:Red soil is formed by weathering of old crystalline igneous and metamorphic rocks. Image of minerals, color, rocks - 108612624 This causes the soil to develop a 'rusty' colour. Red soil in India lacks nitrogenous material, phosphoric acid, organic matter and is rich in iron. Pure silt soils are rare, especially in gardens. Copper toxicity is well described in grazing animals, particularly in Australia where exposure to pyrrolozidine alkaloid containing plants (particularly Heliotropium europaeum, Echium plantagineum, Senecio spp., Amsinckia spp., Crotalaria spp., and Cynoglossus spp.) No acidification was detected after the first year, but in second year soil acidification was taking place. Which soil is characterised by these statements? The two systems were established adjacently along the downward trajectory of the hillslope. Copyright © 2020 Elsevier B.V. or its licensors or contributors. The colour of the soil ranges from deep black to grey. Five bulk soil cores were taken at each soil horizon, and then air-dried and weighed in the laboratory to determine bulk soil density. It contains iron oxides and hence it is red in colour. C. citratus is more commonly grown on soils with higher acidity than C. flexuosus. On the uplands, the red soils are thin, poor and gravelly, sandy or Stoney and porous, but in the lower areas, they are rich, dark and fertile. The soil is mainly found in the country of India as the climate there is suitable for the formation of red soil. The rock being weathered in this area is a 140-million-year-old basalt. Rocks and dust with a color red due to the iron within the structure of the minerals in the soil. Selected Chemical and Physical Properties of Soil Profiles in the Agroforestry System (AF) Consisting of Peanut and Citrus and Monocropping System (MC), Y. Wang, ... S.A. Banwart, in Advances in Agronomy, 2017. The Questions and You can study other questions, MCQs, videos and tests for Defence on EduRev and even discuss your questions like (1994) found that the calculated weathering rate is increased by a factor of 1.3–5 by including biomass uptake and release of calcium, magnesium, and potassium in their weathering model. As water resources are of great priority for human beings in Nepal, as in other industrializing countries, most of the toxicity remediation research and projects are focused on the drinking-water sector. Affected lambs with swayback present from birth with motor dysfunction, including staggering, ataxia, recumbency, and occasionally blindness. For this study, the trees were approximately 3.0 m high, with a canopy width of 3–4 m. The root depth was about 1.1 m (Wang et al., 2011). Can you explain this answer? the soil is orangey-red some soil is dark red or black Does the reddish color of Mars' surface come from its soil? The southwest monsoon, as moderated by the Himalayas, the Western Ghats and other lesser mountain systems, is responsible for the variety of climates found in India. Copper deficiency occurring during gestation in sheep may manifest as congenital enzootic ataxia, or ‘swayback’, and may be due to a primary deficiency due to low soil copper levels (as occurs on volcanic red soils after rain), or secondary to impaired gut absorption, usually from the presence of antagonists such as molybdenum. Wide cracks are seen especially during the dry seasons. Thus, proper use of fertilizers and irrigation yields high production of cotton, wheat, rice, pulses, millets, tobacco, oil seeds, potatoes, and fruits. ... (Figure 10). We also summarized how the iron redox cycling may be affected by other biogeochemical processes or active constituents, such as the nitrogen cycling, the sulfur cycling and humic substances. Berner, ... K.L. Its main component is clay. 3.12), and the effect of the positive charge on its Wien Effect curves could be disregarded. Lateritic soils may contain clay minerals; but they tend to be silica-poor, Lemongrass will grow and produce average herbage and oil yields on highly saline soils. If the answer is not available please wait for a while and a community member will probably answer this On the uplands, the red soils are poor, gravelly, and porous. Rainfall, particularly in the southern parts of the east coast adjoining the Bay of Bengal, is comparatively low during the monsoon period as the area lies in the rain shadow of the Western Ghats. This suggests that pine litter is acidifying the soils and the phosphorous availability in the red soils. In fact, one area has over 12 500 mm of rainfall per year – the world's highest figure. Finally, future research needs pertaining to iron redox cycling coupled to the fate of heavy metals are suggested. Peanut crops grew from the middle of April to the middle of August and were managed in the same way in both the agroecosystems. Red soil is formed by weathering of old crystalline igneous and metamorphic rocks. The hillslope gradient was 6% and the slope length was 130–150 m. The soil depth along the slope ranged from 0.4 to 2.0 m overlying an impermeable parent material horizon. is common and results in accumulation of hepatic copper until a precipitous release occurs, causing a hemolytic crisis and, often, mortality outbreaks. The eastern side of peninsular India has two main divisions: the Deccan Plateau, which lies at an average elevation of about 600 m, and the east coast. The citrus trees were about 3 m high, with the roots penetrating to 1.1 m soil depth and the leaf area index ranging from 4.4 to 5.5 during the growth period. In sandy loam and, Quantifying and Managing Soil Functions in Earth's Critical Zone, km from the Ecological Experiment Station of, km from the Ecological Experimental Station of. K.C. The study area has a subtropical warm humid climate, with an annual mean air temperature of 17.8°C, a minimum of 5.3°C in January, a maximum of 29.6°C in July, and a frost-free period of 262 days. Chemically, red soil is siliceous and aluminous, with free quartz as sand, but is rich in potassium, ranging from sand to clay with the majority being loamy. Laterite soils occupy 130 000 km2 and are composed essentially of a mixture of the hydrated oxides of aluminium and iron, and are found mainly in the hilly regions and on the western coast, especially where the rainfall is heavy and humid conditions prevail. Soil pits were dug in both systems and characterized following soil survey protocols (FAO/SRIC/ISSS, 1998). The soil was analyzed for pH, exchangeable cations, carbon, and available phosphorous (Bray-1) using standard procedures. It forms in tropical and subtropical regions where the climate is humid. Table 1. The Rajasthan or Thar Desert extends to about 100 000 km2. - Quora. Photo about It is a red soil rich in iron. Red soil has high iron content and is fit for crops like red gram, Bengal gram, green gram, groundnut and castor seed. It is rich in iron and hence appears red in colour.plz mark it as brai… However the same area receives rainfall later in the year, in November and December, which is the period of the withdrawal of the southwest monsoon. In well drained (and therefore oxygen rich) soils, red and brown colors caused by oxidation are more common, as opposed to in wet (low oxygen) soils where the soil usually appears grey or greenish by the presence of reduced (ferrous) iron oxide. In India, it is found mainly in Deccan plateau. Red soil is rich in iron oxide, but deficient in nitrogen and lime. Its chemical composition generally includes non-soluble material 90.47%, iron 3.61%, aluminium 2.92%, organic matter 1.01%, Magne­sium 0.70%, lime 0.56%, carbon di-oxide 0.30%, potash 0.24%, soda … Moisture is held in the ring structures. However, the red soil in China has been deteriorating in recent years and facing many threats, such as soil erosion, acidification, and pollution. Although terra rossa exists in other places in the world, these soils are common in areas with Mediterranean-type climates: alternation of a rainy and cool-to warm-dry season. These soils are highly acidic, owing to the leaching of calcium with heavy rainfall. This imparts slipperiness. The selected soil properties are presented in Table 1. But they lack in phosphorous, nitrogen and organic matter. soon. The Red River Valley has some of the richest soil and best farmland in the world. Organic matter makes soil very rich which means it is good for growing crops. In the non-red soils, the available phosphorous content increased. They are usually poor growing soils, low in nutrients and humus and difficult to cultivate. A delayed form may also occur after several weeks of the postnatal period. It looks yellow in its hydrated form. The results summarized in this review may provide insights for solving the heavy metal pollution of paddy soils in the red soil regions. See Article History. Thus, the major process affecting the weathering profile is kaolinitization probably due to the impact of the biota. They are deep and impermeable, clayey in nature. The field experiment was carried out in a small agricultural catchment (Tang et al., 2011; Zepp et al., 2005), about 5 km from the Ecological Experimental Station of Red Soil, Chinese Academy of Sciences (EESRS, CAS) in Yingtan, Jiangxi province, China (28°15′N, 116°55′E). Red soils generally form from iron-rich sedimentary rock. They surround the red soils on their south, east and north. Red soil contains a high percentage of iron content, which is responsible for its color. Due to weathering, the sheets are fragmented. Clay soils are yellow to red. Red soils generally form from iron-rich sedimentary rock. Moulton, in Treatise on Geochemistry, 2003. The color of red soil ranges from red to brown, chocolate, yellow, gray, or sometimes even black. Skaria, ... G. Mathew, in Handbook of Herbs and Spices, Volume 3, 2006. The Himalayas, being well over 6000 m for much of the range, effectively prevent the movement of cold air from the highlands of central Asia and Siberia entering India. Although these findings are mainly based on laboratory experiments, they provide guidance for exploring innovative remediation strategies for controlling pollution of heavy metals in paddy soils of the red soil regions. Mean free adsorption energies of clay fraction of red soil saturated with various chlorides in deionized water (cp are 10 g L− 1 for NaCl, 20 g L− 1 for KCl and NH4Cl, 30 g L− 1 for others) as a function of field strength. At each site, control plots were established, and soil pH and production before and after the lime application was studied. Red soil are developed form Dharwad and Archean rocks. Can you explain this answer? Physics,kinematics.please explain the answer of question? Mars's soil is red because it is very rich in iron oxide, or rust.

Peanut crops were sown at a spacing of 0.20 m × 0.30 m in the middle of April and harvested in the middle of August in both systems. The alluvial soils of the Brahmaputra and the Barak valley are highly fertile and are very much suitable for raising of varieties of crops round the year such as cereals, pulses, oilseeds, plantation crops etc. Types of Soil in … These soils are made up of volcanic rocks and lava-flow. Clay has very small particles that stick together. They readily slide across each other. Such a great diversity of climates supports a correspondingly great variety of plant life. Some of the major crops grown in the red soil in India include groundnut, millets , ragi , rice , potato, sugarcane , wheat , tobacco etc. These soils are neutral to acid in reaction. The elevation at the catchment is 41–55 m above mean sea level. Black soil is of red colour mainly due to its iron oxide content. Introduction of Black Soil. Figure 3.15. We use cookies to help provide and enhance our service and tailor content and ads. The annual rainfall average is 1706 mm during from 1954 to 1999, with approximately 50% concentrated during the period from April to July. A teaspoon of rich soil can contain one billion bacteria. Above this the upper red soil called “Terra Rossa” consists of kaolinite and iron oxides (Benedetti et al., 1994). Soil particle size distribution was measured with the pipette method (Lu, 1999). | EduRev Defence Question is disucussed on EduRev Study Group by 134 Defence Students. EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. It appears that the mechanisms underlying the interactions among these multiple components and processes are not sufficiently understood and may require further studies. One soil profile under each cropping system was excavated and characterized following soil survey protocols in the field (FAO/ISRIC/ISSS, 1998). At stronger fields, differences among ions of the same valence also appear, the ΔGad values of the various cations diminished in the order Ca2 + > Zn2 + > Cd2 + > K+ > Na+ ≥ NH4+. Anup, Subin Kalu, in Soil Remediation and Plants, 2015. Chemically, the black soils are rich in lime, iron, magnesia and alumina. high phosphorus fixation; low plant available water; Yellow to yellow-brown. In AF, four horizontal frames of 1.0 × 0.5 m2 in each soil horizon were exposed vertically, sequentially during pit digging, and the roots in each horizontal frame were counted. Due to transformation in dry and wet climatic condition red soil are formatted by the fission of metamorphic rocks. Red soil – Red soils are found in regions with warm, moderate and moist climates. Laterite, soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. Among these, contamination of heavy metals, particularly arsenic and cadmium pollution in paddy soils of the red soil regions, has become a major environmental concern. Likewise, lime was applied to five vegetable farming sites (cauliflower, potato, tomato and brinjal). Characteristics of Red Soils The texture of these soils can vary from sand to clay, the majority being loams. It extends from the 8° N to the 40° N, a length of over 2500 km, and from latitude 68° E to 97° E, a width of 3000 km. Selected Soil Physical Properties at Different Depths in the Monocropping (MC) and Agroforestry (AF) Systems, H. Brichet, in Encyclopedia of Rose Science, 2003. Both species can be grown on a range of soils and it appears that good drainage is the most important factor. Answers of Red soil is rich in which of these?a)Limeb)Ironc)Magnesiad)Aluminae)All of the aboveCorrect answer is option 'B'. A test has also been conducted on the effects of applying lime to the acidic soils of the Jhikhu Khola watershed. The main features of these soils are their lighter texture and porous, friable nature, an absence of limestone or free carbonates, and the presence of soluble salts in small quantities. This mountain range, which at its highest point is more than 2700 m in altitude, is responsible for the southwest monsoon rains being very heavy on the western side of these mountains and comparatively lighter on the eastern side. The lowermost area of red soil is dark in color and very fertile, while the upper layer is sandy and porous. The study was carried out in a small agricultural catchment (Zepp et al., 2005), about 5 km from the Ecological Experiment Station of Red Soil, Chinese Academy of Sciences (EESRS, CAS) in Yingtan, China. over here on EduRev! Root density, number of roots per square meter. A highly weathered soil that is red due to the high content of iron oxide minerals. Clay soils absorb water, but have poor drainage. Chemical Composition of Red Soils They are acidic mainly due to the nature of the parent rocks. Thus, the Wien Effect in red soil suspensions can be considered to stem from the stripped-off cations alone. Certain other features which affect the climate deserve mention. Red soils denote the third largest soil group of India covering an area of about 3.5 lakhs sq. In the tropics thick layers of weathered soil make access to fresh rock more difficult, but tree roots can penetrate very deeply. Red soils denote the second largest soil … India covers 3.28 million km2. Red soils of Karnataka - definition This type of soil is obtained from the weathering of granite and gneiss. The color of red soil ranges from red to brown, chocolate, yellow, gray, or sometimes even black. 3.15 (Zhu et al., 2009a) as functions of field strength. The research area had a typical subtropical climate with a mean annual temperature of 17.7°C, a maximum daily temperature of around 40°C in summer, and an annual rainfall of 1786 mm. The particles attach easily to iron, manganese and other minerals. It is rich in iron and hence appears red in colour. Image of color, soil, rocks - 108612630 The two agroecosystems were established after a clearance of tea plants (Camellia sinensis L.) in 1982. Approximately 10.6% of the total geographical area of India is covered by red soil, including Tamil Nadu, parts of Karnataka, southeastern Maharashtra, eastern Andhra Pradesh and Madhya Pradesh, Orissa, Chhattisgarh, Chota Nagpur (Jharkhand), south Bihar, West Bengal (Birbhum and Bankura), Uttar Pradesh (Mirzapur, Jhansi, Banda, and Hamirpur), Aravallis, eastern Rajasthan, Assam, Nagaland, Manipur, Mizoram, Tripura, and Meghalaya (http://www.importantindia.com/12596/red-soil-in-india/).
