General principles of FBMPs: "4R"
The basic principle behind fertilizer best management practices is simple, that is the "4R"- using the right fertilizer product(s) at the right rate, right time and right place which conveys how fertilizer applications can be managed to achieve economic, social and environmental goals.
A global framework has been developed to serve as a guide in the development of a country or region , by crop or by nutrient specific FBMPs. Which FBMP to adopt would also depend on the main objectives of the farmers and the society e.g. increase profitability, improve yields, and/or protect the environment, etc. Therefore, there is no “one-size-fits all” best management practices.
FBMPs are developed based on the following principles;
- All stakeholders, i.e. farmer groups, the fertilizer industry, government and non-governmental organizations involved in agriculture, extension and environmental groups must contribute in the development of FBMPs in the country/region.
- FBMPs should integrate the principles of related disciplines such as irrigation, pest and disease management.
- Training and extension, monitoring and audit must be included.
