AgroCares soil testing increases yields by more than 25% at equal costs

Results of field trials comparing farmer practice and AgroCares fertilizer recommendations obtained with AgroCares Soil Scanner

Many African countries aspire to increase productivity in a sustainable way. It is well known that managing soil fertility is essential to sustainably improve yields. Managing soil fertility starts with understanding the nutrient status of the soil and the nutrient requirements of the crops. Until recently executing soil tests with practical fertilizer recommendations was almost non-existent, time-consuming, and expensive in remote areas.

AgroCares introduced Soil Scanners with a NIR sensor and connected to the SoilCares Adviser app in Kenya in early 2017. More than 20,000 farmers have benefitted until now from this on-the-spot soil testing and practical fertilizer recommendations and many testimonies of successful results have been collected. With support from Kenya Market Trust (KMT) field experiments have been conducted to obtain quantitative results and to demonstrate the importance of soil testing to farmers.

In total 10 demonstration plots were established in 3 different counties: Kisii (5), Nyamira (4), and Kericho (1). All plots were planted with maize in the long rainy season of 2019. On each site, 2 adjacent plots of 10×10 m2 were selected; one was treated under conventional (farmers) practice and one was treated following the recommendations after soil testing with the AgroCares scanner.

In all plots where SoilCares’ recommendations were followed, yields exceeded the plots where Farmer’s practice was followed. On average, yields were 25% higher on the SoilCares recommendation plots.  Furthermore, there was no significant difference in the amounts that farmers spent on fertilizers between the Farmers practice plots and the SoilCares recommendation plots.
