Nutrients in the West African Sudano-Sahelian zone: Losses, transfers and role of external inputs

Autor: Buerkert, Andreas Hiernaux, Pierre H.Y.

Crop growth on acid sandy soils of the Sudano-Sahelian zone is primarily limited by the low amounts of organic matter and available mineral nutrients in the topsoil. The shortening of fallow periods with population growth, the exploitation of fire wood, spatial nutrient transfers by wind and wate...

Destructive and non-destructive measurements of residual crop residue and phosphorus effects on growth and composition of herbaceous fallow species in the Sahel

Autor: Gerard, Bruno G. Hiernaux, Pierre H.Y. Muehlig-Versen, B. Buerkert, Andreas

Little is known about the residual effects of crop residue (CR) and phosphorus (P) application on the fallow vegetation following repeated cultivation of pearl millet [Pennisetum glaucum (L.) R. Br.] in the Sahel. The objective of this study, therefore, was (i) to measure residual effects of CR, ...

Strategies to optimize allocation of limited nutrients to sandy soils of the Sahel: A case study from Niger, West Africa

Autor: Gandah, M. Bouma, Jetske Brouwer, J. Hiernaux, Pierre H.Y. Duivenbooden, N. van

Soils used for rainfed cereal production in Niger are sandy, deficient in major nutrients (N and P), and also low in organic matter content. Scarce rainfall with an unpredictable distribution in space and time makes crop and nutrient management difficult. Observations were made in 1996 and 1997...
