Carbon and nitrogen - the key to biological activity, diversity and productivity in a haplic acrisol

Okae-Anti, Daniel; Torkpo, Addison; Kankam-Boadu, Maryross; Frimpong, Kwarne Agyei; Obuobi, Daniel (University of Cape Coast, 2004)

Soil organic matter is important because it impacts all soil quality functions. Much less information is available on the dynamics of the residual carbon and nitrogen content and their distribution incontinuously cropped ...
Analysis of total iodine in soils of some agro-ecological zones of Ghana

Kwakye, P.K.; Okae-Anti, D.; Osei-Agyeman, K.; Frimpong, K.A.; Adams, A.B. (University of Cape Coast, 2004)

. Iodine is beneficial in human nutrition and to a lesser extent in plant nutrition. Availability of this element in the soil is thought to be via ocean-atmosphere precipitation, iodine minerals and redistribution ...
Nitrogen mineralization trends of applied Mucuna pruriens var. utilis

XAhmed, M.; X Osei, M.; Bonsu, M. (University of Cape Coast, 2004-02)

The effect of method of applying Mucuna pruriens var. utilis on the release of mineral nitrogen in an acid soil was investigated in the laboratory. The above-ground parts of M. pruriens were dried, milled and applied at ...
Effect of neem and organic amendments on nematode populations in a coastal savanna tropical soil

Agyarko, K.; Kwakye, P.K.; Bonsu, M.; Osei, B.A.; Asante, J.S. (University of Cape Coast, 2005-04-07)

Nematode numbers were assessed at 2-week intervals in a coastal savanna soil amended with neem leaves and animal manure for 12 weeks under fallow conditions. The number of plant-parasitic nematodes decreased significantly ...
Breakdown of azadirachtin a in a tropical soil amended with neem leaves and animal manures

Agyarko, K.; Kwakye, P. K.; Bonsu, M.; Osei, B. A.; Donkor, N. Asare; Amanor, E. (University of Cape Coast, 2006)

A field investigation was conducted to assess the breakdown of azadirachtin A in a tropical coastal savanna soil amen- ded with neem leaves (NL) combined with poultry manure (PM) or cow dung (CD) using gas chromatography. ...
The effect of organic soil amendments on root-knot nematodes, soil nutrients and growth of carrot

Agyarko, K.; Kwakye, P.K.; Bonsu, M.; Osei, B.A.; Frimpong, K.A. (University of Cape Coast, 2006)
