Where the supply of nutrients in the soil is adequate, crops are more likely to grow well and produce large amounts of biomass. Fertilizers are needed in those cases where nutrients in the soil are lacking and cannot produce healthy crops and sufficient biomass. There are four management objectives associated with any practical farm level operation, including management of fertilizers. These are productivity, profitability, cropping system sustainability, and a favorable biophysical and social environment. Sustainability refers to the medium- and long-term effects of fertilizer management options to maintain or increase the productivity and profitability of the cropping system. Indicators include trends through time in yield, input use efficiency, soil parameters such as N supplying capacity, the presence of organic matter, and profitability. Best management practices for fertilizer support the realization of these objectives in terms of cropping and the environmental health. A strong set of scientific principles guiding the development and implementation of fertilizer best management practices has evolved from a long history of agronomic and soil fertility research. When seen as part of the global framework, the most appropriate set of fertilizer best management practices can only be identified at the local level where the full context of each practice is known. Nutrient stewardship is the efficient and effective use of plant nutrients to achieve economic, social and environmental benefits with engagement from farmers and other stakeholders. This concept essentially describes the selection of the right source of nutrients for application at the right rate, at the right time, and in the right place. Specific and universal scientific principles that apply to these four areas of management are applicable at the farm level. However, the application of these scientific principles may differ widely depending on the specific cropping system, the particular region and the crop combination under consideration. As a practice, nutrient stewardship is dynamic and evolves as science and technology expands our understanding and opportunities; practical experience teaches the astute observer what practices work or do not work under specific local conditions. Decision-support systems guiding the adoption of fertilizer best management practices require a dynamic process of local refinement. Therefore, involvement of individuals knowledgeable in both scientific principles and local conditions is important to this process.
