Journal Article 2000

Autor: Sanginga, P. Vanlauwe, Bernard Merckx, R. Ibewiro, B.

In cover cropping systems in the tropics with herbaceous legumes, plant residues are expected to supply nitrogen (N) to non-legume crops during decomposition. Field experiments were carried out to (i) determine the effects of residue quality on decomposition and N release patterns of selected pla...

Reliable estimates of symbiotically fixed N2 in herbaceous legumes are important in order to determine their role in maintaining or improving N levels in tropical low-external-input farming systems. We have studied the effects of different management systems on the suitability of two non-N2-fixin...

The fate of 15N-labeled plant residues from different cover-cropping systems and labeled inorganic N fertilizer in the organic, soil mineral, microbial biomass and soil organic matter (SOM) particle-size fractions was investigated in a sandy Lixisol. Plant residues were from mucuna (legume), labl...

In cropping systems with limited amounts of external inputs, the soil organic matter pool (SOM) may contribute significantly to plant nutrition. The impact of organic inputs on total SOM and particulate organic matter (POM) N contents as affected by soil type and the relationships between sources...

Quantification of the fate of residue N is essential in low-input tropical cropping systems for the development of management practices that optimize N-use efficiency. The recovery of N from 15N-labeled leucaena (Leucaena leucocephala (Lam.) de Wit) and dactyladenia (Dactyladenia barteri (Hook f ...

In tropical cropping systems with few external imputs, efficient management of mineral N derived from added organic residues is essential for the proper functioning of the system. We studied the dynamics of mineral Nitroden (N) in the top 100 cm of soil with a system tensiometers and suction cups...

The recovery of a single application of leucaena (Leucaena leucocephala) leaf N (78 kg N ha−1) in a maize crop, the hedgerow and the top 10 cm soil of a leucaena alley cropping system was measured for 236 d through the use of 15N labeled residues. The leucaena-derived-N (LDN) was followed in the ...
