Elucidating the causes of low phosphorus levels in ferralsols of Siaya County, Western Kenya

September 2015

Low available soil phosphorus (P) is one of the factors limiting crop production in western Kenya. Availability of soil P depends on amount of apatite, addition of P fertilizers, P fixing potential of a soil, soil water content and P removal by crops. Ferralsols are one of the major soil groups in Siaya County in western Kenya with low available P. We evaluated the possible causes of low available P in Ferralsols in the...
