A review on integrated nutrient management an approach to sustainability

Abstract

Organic manures are used traditionally to supply plant nutrients. The volume of organic fertilizers is high they are bulky in nature so, there are many problems in application of these fertilizes which forces farmers to use synthetic fertilizers. Using organic fertilizers helps to recycle the organic waste. The end product which is obtained from organic waste can provides nutrients in a efficient manner and also improves conditions of the soil. Because synthetic fertilizers which are currently in the use may not fulfil or maintain the quality of soil needs for sustainable agriculture. By applying all essential nutrients through synthetic fertilizers can degrades the quality and health of the soil which directly responsible for unsustainable yields. So, to improve the nutrient supply in integrated nutrient management system chemical fertilizers and organic manures should be combined together for best outputs. To maintain the soil fertility and proper soil health balanced application of organic and inorganic nutrient is required. Through integrated management sustainability in agricultural productivity should be achived. By using Integrated nutrient management on yield components of crops is very important for guarantee of food security. Integrated nutrient management or supply focus at maintening the fertility of soil and nutrient supply for plants to an optimum level in relation to sustain the desired crop productivity by optimizing the all sources of plant nutrients with the help of integrated nutrient management which can also includes other aspects like; maintainence or enhancement of soil productivity by using chemical fertilizers and organic fertilizers in a balanced manner. Different types of organic materials such as bio compost, FYM, green manures, vermicompost, crop residues, industrial wastes, composts, animal manures.
