The overall focus my research is on the development of economically and environmentally sustainable cropping systems, primarily for corn/soybean/cereal production systems predominant in Ontario. Current research projects include: 1) evaluation of reflectance as a crop based indicator for corn nitrogen requirement, 2) determination of sources of temporal and spatial variability in no-till and conventional tillage corn production systems, 3 ) zone tillage impacts on soil properties and corn response, 4) long-term effects of tillage system on soil quality and crop yield, 5) long-term effect of rotations on soil quality, 5) effect of intermittent tillage on soil quality and crop response in a corn/soybean/wheat rotation, and 6) maize response to soil properties. Another complimentary area of research is the development of mechanistic simulation modelling as a means to evaluate and interpret results from cropping system experiments.
