WebThe second, conducted from 1997 to 2000, quantified nitrogen-leaching losses under maize and orchardgrass (Dactylis glomerata L.), as affected by the timing of manure application. Nitrogen-leaching losses were influenced by the timing and rate of nitrogen fertilizer and manure additions, the timing of green-manure incorporation, and soil type. WebHis scientific interests lie mostly in Agronomy, Crop, Greenhouse, Irrigation and Fertigation. His work deals with themes such as Soil water, Leaching and Drainage, which intersect with Agronomy. His studies in Crop integrate themes in fields like Canopy reflectance, Chlorophyll, Normalized Difference Vegetation Index and Dry matter.
