Title: Choice and management of cover crop species and varieties for use in row crop dominant rotations
Author: Samson, Roger; Foulds, Chantal; Patriquin, David
Abstract: The management of cover crops in four major field crops (corn, soybeans, winter wheat and spring cereals) was evaluated over a two year period on farms in South Western Ontario. The research was established within the framework of a corn soybean cereal rotation sequence. The presumption is that from an economic and environmental standpoint this sequence will develop in the 1990's to become the dominant farming sequence used in South Western Ontario on farms that do not grow forages. The experiments are classified in three stages around this rotation with overlap between years. The overall objective of the research trials was to develop crop production systems that maintain or enhance farm productivity and profitability while reducing as much as possible inputs of fertilizer, herbicides and tillage. We propose to achieve this through improving the biological efficiency of the cropping system by: increasing ground cover, adopting a regular rotation of crops, reducing nutrient losses and increasing nitrogen fixation, malting greater utilization of sunlight, improving soil quality and using weed-suppressing living and non-living mulches.
