Research interest
During his industrious tenure with the Sustainable Cropping Systems Lab, Brian was interested in all aspects of organic crop management. His main project was the ‘OCS’ experiment (the Organic Cropping Systems Trial) a comparison of four organic approaches to production of field and vegetable crops. The four systems included: one modeled on a successful organic farm with outstanding production and weed control; one with a variant on that system (higher nutrient additions in the field crops trial and an intensified cropping system in the vegetable trial); one that is similar to typical practices; and one with an experimental organic reduced tillage system using ridge till culture. The field crops trial also includes a conventionally-managed treatment. Crop yield and quality, insect levels, soil nutrients and health, and weeds are being monitored. The project is set to last for 4 years.
