Rice Growing Soils of state

The major area of the state covered with sandy loam to loam with acidic soils (pH 4.5–6.5) and having low fertility. About 66% area of soils are low in available phosphorous content, 18% soils low in K content, 38% soils low in S, 7% soils are deficient in available Zn, 4 % in available copper while 45 % soils are deficient in available boron in the state. More than 70% of soils are deficit in organic carbon and micronutrients Majority of soils of the state have medium status of available nitrogen (280-560 kg/ha) and about 19.6% area have low available N content. About 49% area of soils are extremely acidic to strongly acidic (pH <5.5) and 36% area suffering from moderate to slight soil acidity (pH 5.6-6.5) while neutral soils (pH 6.6-7.3) accounts for only 8% in the State. The water holding capacity of the State soil is very low due to porous nature of the soil and undulating topography. Depending upon topography, soils are broadly classified into Upland, Medium land and Lowland. The region has a large number of small and marginal farmers (<2 ha), approximately 80%, but they own hardly 30-35% of the cultivable land.
