dc.description.abstract The objective of this study was to investigate the effects of using the blade roller for no-till/reduced tillage in organic green manure management. The study was conducted in Carman, Manitoba and Oxbow, Saskatchewan. In the spring, a pea/oat intercrop was seeded as a green manure. The green manure was terminated by rolling, tilling, or a combination of the two. The following spring, spring wheat was seeded. In the year of the green manure, measurements taken included: biomass, soil nitrogen, and ammonia emissions. In the year of the wheat, measurements taken included: soil cover, soil moisture, weed competition, soil nitrate-N, and wheat biomass. Results showed increased soil cover, minimal effect on soil moisture, delayed wheat development, an effect on weed communities, reduced rate of nitrogen release, and reduced wheat yield. No-till green manure management can therefore provide benefits of soil conservation and nitrogen conservation but may result in decreased wheat yield. en
