New nitrogen-fixing soil fertility method boosts crop production in Kenya
by Bob Koigi
An innovative method of boosting soil fertility has increased yields for farmers in Western Kenya by up to 10 times, promising to increase harvests and boost nutrition if adopted on wide scale.
The four-year project, which was launched last year, has raised the net returns for farmers who adopted the legume and rhizobial inoculant technologies.
Launched in Kenya and seven other African countries to triple the take-up of free atmospheric nitrogen through Biological Nitrogen Fixation, the project has delivered near-instant benefits through improved crop and livestock productivity, nutrition, farm income and soil health.
It has also sparked a revolution in legume processing, specifically of soya, in Western Kenya.
The project’s total benefits at the end of the four years are projected to be at least $31.9 million based on estimates of the increased…
