Nitrogen fertilizer equivalencies of organics of differing quality and optimum combination with organic nitrogen source in Central Kenya

Autor: Kimetu, J.M. Mugendi, DN Palm, C.A. Mutuo, PK Gachengo, CN Bationo, B. André

Decline in crop yields is a major problem facing smallholder farmers in Kenya and the entire Sub-Saharan region. This is attributed mainly to the mining of major nutrients due to continuous cropping without addition of adequate external nutrients. In most cases inorganic fertilizers are expensive...

Soil PH and nitrogen changes following cattle and sheep urine deposition

Autor: Somda, Z.C. Powell, J.M. Bationo, B. André

The changes in soil pH and mineral N concentrations of cattle and sheep urine patches were compared to those occurring in fertilizer urea placement zones in a study in Niger. Urine and fertilizer solutions each containing 400 mg N (800 kg N/ha) were spread onto individual plots covering a surface...

Partial balance of nitrogen in a maize cropping systems in humic nitisol of Central Kenya

Autor: Kimetu, J.M. Mugendi, DN Bationo, B. André Palm, C.A. Mutuo, PK Kihara, Job Nandwa, SM Giller, Ken E.

The application of nitrogen in a soil under agricultural production is subject to several pathways including de-nitrification, leaching and recovery by an annual crop. This is as well greatly influenced by the management practices, nitrogen source and soil conditions. The main objective of this s...
