Bio Fertilizer and their Use in Field Crops

Bio fertilizer are formulations of living cells of some beniefical micro–organisms with suitable carrier materials. These micro-organism benefit plant by supplying and facilitating uptake of nutrients (mainly nitrogen and phosphorus) we all know that nitrogen and phosphorus are two major plant nutients for for plants growth. These are generally supplemented through chemical fertilizer, however a major portion of the nitrogen is lost due to leaching and evaporation. Again, due to acidic nature of soil pH of N Eregion, major, portion of phosphorus remains insoluble or unavailable to plants. Moreover, harmful effect on soil due to injudicious use of nitrogenous and phosphates fertilizer can not be denied. It is gift of nature that we have a number of micro-organisms which can help the farmers in nitrogen and phosphorus nutritiocn in a cost effective and eco friendly organic way.
