Micronutrients (Fe, Mn, Zn & Cu) Balance and Nutrition under Long Term Application of Fertilizer and Manure in a Tropical Rice-Rice System
Micronutrient balance in soils is important in nutrient use efficiency, environment quality protection, and the sustainability of agro-ecological system. The deficiency or excess of micronutrients, such as Fe, Zn, Mn and Cu, in the plough layer may cause reduction in crop yield and/or quality. Therefore, it is essential to maintain soil micronutrients in appropriate levels, not only satisfying plant needs but also preventing any potential build-up of certain nutrients in order to sustain agricultural production. A long term fertilizer experiment started in 1969 is being carried out at Central Rice Research Institute, Cuttack, Odisha, India. In this experiment, a study was conducted to analyze the balance of micronutrients and their interrelationship.
