Nitrogen mineralization and crop uptake from surface-applied leaves of green manure species on a tropical volcanic-ash soil

Autor: Cobo Borrero, Juan G. Barrios, E. Kass, DCL Thomas, Richard J.

Leaves of nine green manure (GM) species were surface applied to a tropical volcanic-ash soil at a rate of 100 kg N ha 1 in order to evaluate their N-fertilizer value in a glasshouse experiment. GM treatments were compared to urea at two rates, 50 kg N ha 1 (FN50) and 100 kg N ha 1 (FN100), and t...

Simulating phosphorus responses in annual crops using APSIM : Model evaluation on contrasting soil types

Autor: Delve, Robert J. Probert, ME Cobo Borrero, Juan G. Ricaurte Oyola, José Jaumer Rivera Pena, M Barrios, E. Rao, Idupulapati M.

Crop simulation models have been used successfully to evaluate many systems and the impact of change on these systems, e.g. for climatic risk and the use of alternative management options, including the use of nitrogen fertilisers. However, for low input systems in tropical and subtropical region...
