Re: iari soil science
The Division of Soil Science and Agricultural Chemistry was established in 1905 with the establishment of the Imperial Agricultural Research Institute housed in the Phipps Laboratory The main objective of this Division is to carry out research on the fundamental and applied aspects of the physical, chemical and biological properties of soil; fertilizers and manures and their interaction with soil and plant; improvement and maintenance of soil fertility for sustained optimum agricultural production It has made outstanding contributions both of theoretical and practical value in many fields extending over the various aspects of soil science and agricultural chemistry. Some of the land mark contribution/concepts are given below: First soil testing laboratory in the country First laboratory in the country on use of radio tracers in plant nutrition studies. Equilibrium phosphate potential and potassium adsorption ratio Targeted yield concept of fertilizer recommendation Contribution of non-exchangeable potassium in plant nutrition Phasing of fertilizer phosphorus in cropping systems Potassium carbonate as an extractant of soil available phosphorus First soil map of India First cow-dung gas plant Alkaline permanganate method of soil available nitrogen First soil fertility (N, P & K) maps of India Cated calcium carbide as nitrification inhibitor Non-linear regression techniques for critical limits Establishment of VAM in rice-wheat cropping system. First soil boron fractionation scheme compatible with colorimetry Pusa digital soil test fertilizer recommendation (STFR) meter The Division is equipped with modern instrumental facilities (AAS, ICP-MS, XRD, Petrological microscope, Auto-analyser etc.) to address the emerging frontier areas of soil research.
