In 2013, Samuel Rigu was looking for a new challenge. Having grown up in a rural Kenyan farming family, he knew that farms in his village depended on synthetic fertilizers.
On a continent where land degradation has driven millions of people out of their villages and into cities, fertilizer is often a must for farmers. However, African farmers pay two-to-six times the average world price for fertilizers due to a heavy reliance on imports, combined with high transportation costs and a dearth of suppliers in the countryside. Rigu wanted to change that.
