Senna siamea trees recycle Ca from a Ca-rich subsoil and increase the topsoil pH in agroforestry systems in the West African derived savanna zone

Autor: Vanlauwe, Bernard Aihou, K. Tossah, B.K. Diels, J. Sanginga, Nteranya Merckx, R.

The functioning of trees as a safety-net for capturing nutrients leached beyond the reach of crop roots was evaluated by investigating changes in exchangeable cations (Ca, Mg, and K) and pH in a wide range of medium to long term alley cropping trials in the derived savanna of West Africa, compare...

Nitrogen management in adequate input maizebased agriculture in the derived savanna benchmark zone of Benin Republic

Autor: Vanlauwe, Bernard Aihou, K. Houngnandan, P. Diels, J. Sanginga, N. Merckx, R.

Although the West-African moist savanna zone has a high potential for crop production, yields on farmers' fields are, on average, far below this potential, mainly due to the low use of external sources of nutrients. Since the mid-1990s, it has become clear that in order to upgrade crop production...

The ability to fix N is not the only key to delivery of the benefits of BNF to farmers: experience of IITA in the savannas of Africa

Autor: Carsky, R. Sanginga, N. Schulz, S. Douthwaite, Boru Manyong, Victor M. Diels, J. Vanlauwe, Bernard Keatinge, J.D.H.

The IITA in its research for sustainable soil fertility management has passed through several stages during which legume-based systems were always at the forefront. Alley cropping has N yields of more than 200 kg ha-1 with 50% N2 fixation. In the case of Mucuna cover cropping, the ecological bene...
