Journal Article 1998

Autor: Powell, J.M. Ikpe, F.N. Somda, Z.C. Fernández Rivera, S.

Most farming systems in semi-arid West Africa rely on organic matter recycling for maintaining soil fertility. The cycling of biomass through ruminant livestock into dung (faeces) and urine that fertilize the soil has long been an important factor in the nutrient cycling processes of these integr...

In the process of developing an improved fallow system based on forage legumes, the potential interest of crop-livestock farmers in enhancing soil fertility restoration and dry-season feed supply was assessed during a socio-economic study on 11 farms of settled agro-pastoralists in the subhumid z...

A study was conducted in the humid-forest, forest-savanna, and Guinea savanna zones of West Africa from 1993 to 1999 to examine the effect of managing crop residues from cereal-legume cropping systems for mulch and fodder for sheeIncreasing the proportion of total crop residues produced from a un...

Journal Article 2000

Autor: Haque, I. Lupwayi, N.Z. Tadesse, T.

Alfisols, Vertisols, Inceptisols, Aridisols, Mollisols, and Entisols were sampled (0-30 cm) from 32 locations across Ethiopia. The soils were analyzed for copper (Cu), zinc (Zn), manganese (Mn), and iron (Fe) contents using 0.005 M diethylene triamine pentaacetic acid (DTPA), 0.05 M hydrochloric ...

Sustainable land use in periodically dry Brazilian savannas requires a water-saving management. We hypothesized that the annual course of matric potentials (?M) in very-fine, isohyperthermic Anionic Acrustoxes of Pinus plantations (PI), degraded (DP) and productive pastures (PP), no-till (NT) and...

Planted tree or shrub fallows can help increase the fertility of degraded tropical soils. We investigated the effects of planted fallows of Indigofera (IND), Calliandra (CAL), and Tithonia (TTH); a natural, unmanaged fallow (NAT); and a maize/bean rotation (ROT) on the dynamics and partitioning o...

Oxisols such as those of the Colombian Eastern Plains (Llanos) are susceptible to physical, chemical and biological degradation once brought into cultivation, especially under intensive use of machinery. The main objective of this study was to determine the impact of intensive disc harrowing (2, ...
