Abstract: A field study entitled “Long-term impact of organic and inorganic fertilization on physico-chemical properties of soil under wheat-maize cropping system in Heplustepts†was conducted during Kharif 2016-17 and 2017-18 in the Long Term Fertilizer Experiments initiated in Kharif, 1997 at the Instructional Farm of the Rajasthan College of Agriculture, Udaipur. The results of the present investigation revealed that different treatments have not shown any significant effect on soil pH. However, application of 20 t ha-1 FYM significantly increased CEC of soil followed by 100% NPK+ FYM 10 t ha-1 application. Application of FYM alone recorded highest soil organic carbon and total organic carbon content of soil. Application of FYM @ 20 t ha-1 gave lowest bulk density and significantly maximum total porosity, water holding capacity and hydraulic conductivity of soil followed by FYM 10 t ha-1 + 100% NPK treatment. Application of 100% NPK+ FYM 10 t ha-1 and 150% NPK increased availability of N, P and K as compared to other treatments. Significantly maximum available S was recorded with the application of 100% NPK + Zn + S. Application of FYM @ 20 t ha-1 recorded the highest availability of Fe, Cu and Mn in soil. Whereas, highest DTPA- Zn was observed with 100% NPK +Zn application.
