Abstract: The experiment was conducted at the farmer field, Delang block of Puri, Odisha, India, for three consecutive years (2013-14 to 2015-16) to study the effect of SSNM with nutrients omission technique on chemical properties and nutrient status of soil in rice-maize-green gram cropping system. The experiment was comprised of 10 treatments (SSNM, SSNM-N, SSNM-P, SSNM-K, SSNM-S, SSNM-Ca, SSNM-B, SSNM-Zn, farmer practice and absolute control) with application of FYM @ 3 t/ha to all treatment except absolute control. The finding revealed that SSNM based nutrient application increase the soil pH, soil OC, cation exchange capacity, base saturation, available N, P, K, and S respectively over initial values and other nutrient omission SSNM treatments. Among the micronutrient, availability of Mn and B were decreased over initial values in all the treatment except Zn omitted treatment. The availability of Zn was maximum in phosphorous omitted SSNM treatment. Thus SSNM based nutrient management was best approach for improving chemical properties and nutrients availability to plants.
