Peri-urban agricultural management impacts the soil nutrient status of Nitisols in the central highlands of Kenya

Urban Farm DB summary

An evaluation of soil profiles, surface soil conditions, and nutrient management was conducted in Kiambu County, Kenya, at the Tigoni experimental station and 26 surrounding small-scale peri-urban farms. The study found significant differences in surface soil nutrient status between the experimental station and surrounding farms, with available phosphate and exchangeable calcium levels being excessively high in nearly half of the peri-urban farms, contrary to past findings. In contrast, phosphate levels at the experimental station were mostly deficient, and magnesium was deficient in both settings.
