System Based Integrated Nutrient Management

Integrated nutrient management involving different organic sources like FYM, vermi-compost, crop residue, green manure, Bio-fertilizer and in-situ role of legumes along with balanced nutrient use (major and micro-nutrients) deserves due attention. In fact, based on series of experiments and studies conducted all over the country with reference to nutrient management for various crop as applicable to varying soil environment representing different agro-climatic zones have been generated at national level but the system based information’s on integrated nutrient management is still lacking and yet to be documented. In this publication 1, 3 and 4 deals with general issues and management options for integrated nutrient management with special reference to irrigated eco-system, while 2 focused on crop residue management. The 5 and 10 are enlightens the soil-test based nutrient management for sustainable soil health, while s 6 and 7 are related to nutrient economy through integrated farming system and inclusion of legumes under cereal based cropping systems. The 8 is focused on integrated nutrient management in rice-wheat cropping system, while 9 on oilseed based, 11 on soybean based, 13 on vegetable and 23 on seed spices based cropping systems. The issues related to SSNM, protected agriculture, soil chemical, biological and microbial diversity are discussed in 12, 14 and 18, respectively. The aspects related to system based nutrient budgeting, soil carbon management and sequestration, balanced crop nutrition in relation to crop diseases, economics and nutrient modeling have been duly discussed in s from 19 to 25.
