Kinyua, MichaelCao Diogo, Rodrigue V.Sibomana, JeanBolo, Peter OmondiGbedjissokpa, GloriaMukiri, JessicaMukalama, JohnPaul, BirtheSommer, RolfKihara, Job[Green manure cover crops in Benin and Western Kenya - A review.]Green manure cover crops in Benin and Western Kenya - A review.

Phosphate rock (PR) is an alternative fertilizer to increase the P content of P-deficient weathered soils. We evaluated the effects of fertilizer form on indicators of biological cycling of P using an on-farm trial on a Rhodic Kandiudox in western Kenya. Treatment plots were sampled after 13 crop...

Crop production in sub-Sahara Africa is constrained by low soil phosphorus (P) content. A study was conducted in western Kenya to explore alternative P inputs and ways of optimizing their effectiveness and profitability. A field experiment established in 2007 studied the effects of Minjingu phosp...

Productivity in Crop-Livestock Systems can be maximized using Integrated Soil Fertility Management (ISFM). ISFM combines (i) improved germplasm (ii) mineral fertilizer application (iii) organic matter management and (v) adapted agronomy. CIAT established a long-term trial in Western Kenya in the ...
