histosolsThere are no large contiguous areas of peats in Kerala. These are organic rich soils with organic matter, Hemists or Saprists that develop in lower topographic positions in a permanent water saturated environment. High acidity and high content of sulphidic material are associated with Histosols. These soils present numerous nutrient management problems and need special management for optimum returns. Cultivation of Histosols with organic layers result in decomposition of organic matter with concomittent shrinkage of soils. Upon shrinkage, the permanent water table comes to the surface and reduces the soil quality. These soils are identified in Kuttanad Kari lands.
