Managing Soil Acidity - 2014 Phase 2 Trial Report

Agricultural innovation
One Acre Fund worked with various partners to better understand the science of soil pH changes and consider
ways to modify common lime application practice to suit the smallholder context.
By One Acre Fund and Kelvin Owino

We sought to evaluate the potential impact of lime application under standard practice conditions. Through consultation with experts in the field we determined a quantity of lime likely to produce a strong yield response. In addition to quantity we targeted the most appropriate lime application method. By broadcasting lime evenly over the field two months prior to planting we intended to allow sufficient time for initial pH changes in the soil to occur. As the soil acidity neutralization capacity of lime takes weeks to months an early application, it was believed, would further increase the likely yield response.
