ICRISAT, India soils: yesterday, today and tomorrow uri icon

abstract

  • Associated red and black soils are common in the Deccanplateau and the Indian peninsula. The red soilsare formed due to the progressive landscape reductionprocess and black soils due to the aggradation processes;and they are often spatially associated maintainingtheir typical characteristics over the years.These soils are subject to changes due to age-longmanagement practices and the other factors like climatechange. To maintain soil quality, it is essential tomonitor changes in soil properties preferably usingbenchmark (BM) soil sites. One such example lies atthe International Crops Research Institute for theSemi-Arid Tropics (ICRISAT) farm in Patancheru,India where red (Patancheru) and black (Kasireddipalli)soils co-exist in close association under almostsimilar topographical condition, which also representsvery commonly occurring spatially associated soils.The database generated over the years for these twodominant soils that are under cultural practices forthe last 2?3 decades, helps us understand the relativechanges in properties over a time scale. To do thisexercise, we revisited the BM spots as the data on theoriginal characterization of these soils since the development of the farm, are available, for comparativeevaluation. We also attempted to make prediction offuture changes in properties for these two importantand representative black and red soils of the ICRISATfarm in Patancheru, India
