New age nutrient carriers for rice based cropping systems

Abstract

Soil fertility and plant nutrition are remained together in agricultural sciences and play a vital role in sustainable production in rice based growing areas. However, recent interest in attaining sustainability in agriculture made a way to high utilisation of natural resources to enhance the soil fertility and plant nutrition through possible ways that are expected to be increased in near future. Moreover, there is an escalating direct pressure on demand of agricultural production with limited resources, which can be mauled with a combined use of mineral nutrient and natural resources, recycling of waste materials and growing of efficient genotypes. Increasing rice yield under a constraint environment has to be addressed with the rational use of chemical fertilizers including the introduction of multi nutrient mixtures, novel fertiliser materials coupled with the involvement of natural sources of nutrition in the nutrient management in rice based cropping systems. Imbalanced fertilization is causing a major reduction in yield and low nutrient dense grains in rice based cropping areas. Generally, nutrient management is carried out by application of conventional high analysis compounds solely or mixed with other nutrient fertilisers.
