Fertilizer Optimization Tools
OFRA research is generating fertilizer response curves and reviewing findings from previous research. This data is mapping out the relationship between the application of nutrients and the crops produced.
One of the key outputs of this work is the development of over 60 Fertilizer Optimisation Tools. This approach differs from much of the previous work because it assumes that farmers should be pursuing profit maximisation and not maximising the yield. So, smallholders are led through a series of questions about what they need to grow and what they feel crops will be worth at the end of the season. This helps to shape their crop choices and decide on how to place inputs including guidelines on fertilizer.
The film, Optimizing Fertilizer use in Uganda, gives a detailed description of how the Fertilizer Optimization Tool works. The tool is available in both English and French languages.

The Fertilizer Optimization Tools have been customized within countries to reflect the agro-ecological zones that exist.
The Fertilizer Optimization Tools will work on any PC, and for areas where this is not practical, look up tables can be created.
