Integrated nutrient management: Preliminary results from a 2-year field trial using cowdung, mineral fertilizer and maize test crop in the interior savanna zone of Ghana

Sakyi, C. A.; Abunyewa, A. A.; Nyamekye, A. I.; Safo, E. Y. (Ghana Journal Agriculture Science, 2005)

On station trials were conducted in 2 years at Manga Research Station in the interior savanna zone of Ghana to evaluate integrated nutrient (cowdung and mineral fertilizer) management for sustianable maize production. The ...
Soil Fertility Status and Potential Organic Inputs for Improving Small Holder Crop Production in the Interior Savanna Zone of Ghana

Fening, J.; Gyapong, T.; Ampontuah, E.; Quansah, G.; Danso, S. (Taylor & Francis, 2005)

Soil fertility decline is a major problem facing smallscale farming in Sub-Saharan Africa. To optimize the productivity of fertilizer usage, it is imperative that the fertility status of the soil is known. This study ...
Intercropping maize with planted fallows on smallholder farms in Ghana

Gaisie, E.; Adjei, T.; Ababio, F.; Fening, J. (John Wiley & sons, 2005)

t Sowing maize in planted fallows of the forage legumes Centrosema, Macroptillium and Stylosanthes increased total maize yield by over fourfold, and a partial budget analysis indicated that the use of the legumes would ...
Extent and Management of Low pH Soils in Ghana

Buri, M. M.; Issaka, R. N.; Wakatsuki, T. (Taylor & Francis, 2005)

A review of soil acidity problems with regards to causes, extent and management in Ghana shows that the extent of soil acidity has changed within a period of 2-3 decades. In the 1970s’ soil acidity was a major problem ...
Fertilizer and residue quality effects on organic matter stabilization in soil aggregates

Fonte, S. O.; Yeboah, E.; Ofori, P.; Quansah, G. W.; Vanlauwe, B.; Six, J. (2009)

This study examined the influence of organic residue quality and N fertilizer on aggregate-associated soil organic matter (SOM) in maize (Zea mays L.) cropping systems of southern Ghana. Six residue treatments of differing ...
