3329. MacRae, R.J. and G.R. Mehuys. 1985. The effect of green manuring on the physical properties of temperate-area soils.. Advances Soil Sci. 3:71-94.
This is a review chapter focusing on the non-nutrient benefits of green manures (e.g. soil physical improvement, particularly for corn in temperate climates. Organic matter plays more of a role in aggregate stability than in aggregate formation. This occurs through the by-products of organic matter decomposition (microbial gums and mucilages). Low-N green manures (1.5% N or less) generally are more effective in building organic matter levels. While sweeping conclusions are difficult, the benefits of green manuring on crop yield are most apparent during dry periods, particularly in rainfed production systems.
