Fertiliser Best Management Practices in Important Cropping Systems

摘要

Nutrient management is a major component of soil and crop management system. It becomes even more important in intensive high yielding cropping system because of the increasing energy cost and economic pressure. Fertiliser best management practices (FBMPs) which emphasise on better crops and soil management strategies are meaningful options to attain sustainable higher yields. FBMPs focus on site-specific nutrient recommendations, its intensive management, improved efficiency and effectiveness, and environmentally sound use of crop production inputs. Infect the concept of applying the right fertiliser at the right time, right rate and at right place is a guiding theme for FBMPs. The intent of this publication is to compile the information available on FBMPs for predominant cropping systems of the country covering the various aspects like concern of multi-nutrient deficiencies, yield gaps and means to bridge these, site-specific nutrient management. In order to tailor the BMPs at small field holders managing spatial field variability using modern tools like remote sensing, GIS, sensor based nutrient management, and nutrient experts are also discussed.
