Nutrient Expert? – Going Global with Improved Fertilizer Recommendations

摘要

Addressing the challenge of making science-based fertilizer recommendations to smallholder farmers throughout Asia and Africa has been a key focus of IPNI staff over the decades. As students of agriculture we all learned about soil testing methods, correlation and interpretation as the key step in this process. However, this entire approach has not been successful on smallholder farms due to access, cost or inadequate timeliness in delivery of results. As a result, some alternative had to be found to address this problem for smallholder farmers in Asia and Africa.
