Development and Dissemination of 4R Nutrient Stewardship Knowledge to Support Crop Production Intensification in Western Kenya
IPNI-2013-SSAP-2
Inappropriate fertilizer recommendations and lack of access to information on good nutrient crop and nutrient management practices is a key factor underlying low crop productivity in sub-Saharan Africa (SSA). Read more
Interpretive Summary
There is an urgent need for the sustainable intensification of crop productivity in smallholder farming systems, given the current low productivity levels which frequently fall short of meeting the food needs. The 4R Nutrient Stewardship principles provide a framework that help farmers have sustainable increases in their crop yields and profits. Results from a project over the past four years illustrate that this is feasible.
The lack of appropriate site-specific nutrient management recommendations is one of the key underlying factors for low crop productivity in sub-Saharan Africa (SSA). The 4R Nutrient Stewardship Framework, developed by the fertilizer industry, aims to provide the context for efficient nutrient management focusing on four central components: applying the right fertilizer source, at the right rate, at the right time in the growing season, and in the right place.
