“…This type of degradation ultimately modifies the soil physical and chemical properties. Such modifications resulting through the regressive pedogenesis 12 restrict the entry of rain water, and reduces the storage and release of soil water 13 . The lack of soil water impairs the possibility of growing both rainy and winter crops in a year, in vast areas especially in black soils of SAT with mean annual rainfall (MAR) <1000 mm (ref.…”

Associated red and black soils are common in the Deccan plateau and the Indian peninsula. The red soils are formed due to the progressive landscape reduction process and black soils due to the aggradation processes; and they are often spatially associated maintaining their typical characteristics over the years. These soils are subject to changes due to age-long management practices and the other factors like climate change. To maintain soil quality, it is essential to monitor changes in soil properties preferably using benchmark (BM) soil sites. One such example lies at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) farm in Patancheru, India where red (Patancheru) and black (Kasireddipalli) soils co-exist in close association under almost similar topographical condition, which also represents very commonly occurring spatially associated soils. The database generated over the years for these two dominant soils that are under cultural practices for the last 2-3 decades, helps us understand the relative changes in properties over a time scale. To do this exercise, we revisited the BM spots as the data on the original characterization of these soils since the development of the farm, are available, for comparative evaluation. We also attempted to make prediction of future changes in properties for these two important and representative black and red soils of the ICRISAT farm in Patancheru, India.

“…The release of Ca 2+ ions from soil modifiers prevents a rise in pH and ESP and improves the soil hydraulic properties to obliterate the effect of high ESP. As suggested, the lower limit of sodicity at ESP > 40 for soils of the Indo‐Gangetic Plains (IGP) (Abrol and Fireman, 1978), at ESP >5 but <15 for Indian Vertisols (Kadu et al, 2003), or the limit of ESP 6 for Australian soils or >15 for all soil types (Soil Survey Staff, 1999, 2003) appears to be redundant for the zeolitic sodic Vertisols of India. In view of the pedogenetic processes controlling the hydraulic properties of soils mediated through dispersibility, the most important factor for soil degradation (Sumner, 1995), grouping soils on the basis of saturated hydraulic conductivity ( K s ) appears logical.…”

More than 50 yr ago US soil taxonomy was adopted in India. Since then many researchers have contributed their thoughts to enrich the soil taxonomy. The National Bureau of Soil Survey and Land Use Planning (NBSS & LUP) (Indian Council of Agricultural Research) as a premier soil survey institute has been consistently using benchmark soil series to understand the rationale of the soil taxonomy, keeping in view the soil genesis from different rock systems under various physiographic locations in tropical India. The present review is a humble effort to present this information.

“…To estimate LGP, 100 mm m -1 water has been used as standard for the deep soils assuming this amount to be the measure of available water after cessation of rains. Later Kadu et al (2003) reported this measure to be an over estimation. This demanded estimation of the LGP to be modified .…”

Agro-Ecological Sub-Regions (AESRs) of the country were conceptualized using limited soil data and accordingly a map was generated way back in 1994. The present paper revisits the AESR concept to revise this map with the help of georeferenced soil information system (GeoSIS) recently developed at the sub-country levels of the Black Soil Region (BSR) and the Indo-Gangetic Plains (IGP). GeoSIS has been proved to be an excellent tool in successful application of AgroEcological Sub Regions (AESRs) at the regional and national levels. This novel approach could narrow the knowledge gap in revising the soil and agro-management technologies, used in dry land agriculture for productivity enhancement with special reference to the BSR dominated by cotton and soybean cropping systems. For the IGP, similar approach was used for the rice-wheat cropping systems. Revised AESR map identifies the areas under different level of productivity of these four important crops of two major food-growing regions of the country. The identified areas in the form of thematic maps shall help the planners and land resource managers to prioritize areas for resource management.
