Geosoil permite almacenar, consultar e interpretar información tanto del suelo como de su entorno biofísico a diferentes escalas: parcela, finca, comunidad, municipio, departamento, región, país. Opera a partir de una base de datos relacional elaborada en ACCES 2000, compuesta por una serie de ta...

In Kenya the belowground biodiversity project was implemented in Embu and Taita which are biodiversity hotspots. The objective of the paper is to present and analyze farmers’ knowledge, attitudes and practices at different timelines of the project, as well as identify factors limiting adoption of...

Bean ( Phaseolus vulgaris check for this species in other resources L.) production in Africa is constrained by edaphic stresses. A pan-African effort, Bean Improvement for Low Fertility in Africa (BILFA), was initiated in 1990 to screen beans for tolerance to several edaphic stresses. In the fir...

Results based on a socioeconomic survey on flood plain forest fallows are presented. The study was aimed at identifying the factors influencing people's decisions on land use and forest resource utilisation, and to provide some preliminary biophysical information. It was found that 93% of local l...

To determine the efficiency of utilization of organic matter in agricultural production, nitrogen flow was estimated within a village-farm model in the west of Niger, West Africa. Nitrogen was focused on in this study as it is known to be a major nutrient component of organic matter and one of th...


Hayashi, K.Matsumoto, N.Hayashi, E.Abdoulaye, TahirouShinjo, H.Tabo, RamadjitaMatsunaga, R.Tobita, S.[Estimation of nitrogen flow within a villagefarm model in Fakara region in Niger, Sahelian zone of West Africa]Estimation of nitrogen flow within a villagefarm model in Fakara region in Niger, Sahelian zone of West Africa

Where there is limited availability of conventional fertilizers, the use of organic materials is considered a viable alternative to increase the productive capacity of soils. Many potential plant residues remain underutilized due to limited research on their use as a nutrient source. In this stud...

Populations of Legume Nodulating Bacteria (LNB) were assessed under glasshouse conditions in soils collected from selected landuse systems in Taita Taveta district, Kenya. The populations were estimated by the most-probable-number (MPN) plant infection technique using Macroptilium atropurpureum (...

A glasshouse experiment was conducted to determine how reduction conditions would affect plant nutrient availability and uptake in a red-yellow latosol (Acrustox). Soil analysis showed that the most important changes were a marked increase in extractable iron and an inhibition of nitrification. T...
