How Kenya Can Increase Access to Subsidized Fertilizer and Certified Maize Seeds for Smallholder Farmers

Image
  Access to affordable agricultural inputs remains a key factor affecting food production, farm profitability, and food security in Kenya. For thousands of smallholder farmers, the cost and availability of fertilizer and certified maize seeds can determine whether they achieve a good harvest or struggle with low agricultural productivity.
