63 per cent of Kenya’s arable land is acidic, with nearly seven million acres classified as strongly acidic, Agriculture CS Mutahi Kagwe has said. He warned that applying fertilizer without first addressing soil acidity could leave farmers spending money without achieving expected yields. Speaking at KALRO Kabete, during the launch of  the National Soil Partnership, National Soil Laboratory Network and the national rollout of the Global Soil Doctors Program Kagwe  also directed KARLO to analyze about 77,000 soil samples from 45 counties and develop county-level soil fertility maps.
