Advances in integrated plant nutrient management

Chapter synopsis: Integrated plant nutrient management (IPNM) based on the combined use of organic amendments and mineral fertilisers was designed to address the concerns of deteriorating soil health and negative yield trends commonly observed with long-term fertiliser use. Yield of most crops obtained by following IPNM are higher than that observed by applying same amount of nutrients through organic manures or inorganic nutrient sources alone. This chapter examines recent research on IPNM in terms of increasing crop yields, long-term sustainability of crop yields and improvement/ maintenance of soil health. The chapter discusses the potential contribution of INPM to global warming through emission of nitrous oxide. The chapter focuses particularly on Sub-Saharan Africa, where most soils are already degraded in terms of loss of nutrients and organic matter and Integrated Soil Fertility Management (ISFM) as a variant of IPNM has been suggested as the only way to manage soil fertility. Finally, the chapter looks ahead to future research trends in this area.
