Field experiments were designed to investigate the effectiveness of integrated soil fertility management (ISFM), comparing fertilizer use efficiency and its impact on millet, cultivated close to the homestead ( infields ) and away from the homestead ( outfields ). Millet yields and response to N ...

Millet nutrient use efficiency as affected by natural soil fertility, mineral fertilzer use and rainfall in the West African Sahel
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...

Our study on soil N dynamics was conducted in the rainy season of 2005 and 2006. It focused on the effects of soil managements with sole and combined applications of mineral and organic fertilizers in the long-term experiment conducted since 1993 in the Niamey Center of the International Crop Res...

Micro-dosing technology has been developed by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) and its partners to help subsistence farmers in the Sahel improve inorganic fertilizer application. However, the ICRISAT's recommendations regarding fertilizer application ...

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...
