Undersowing legume crops for green manuring of lettuce

Biological Agriculture & Horticulture, 2003
The objective of this experiment was to investigate the potential of several species of undersown legume crops to deplete soil nitrate and to accumulate nitrogen. A further objective was to measure the effects of the legume crops as a green manure for a succeeding early lettuce crop.

Green manure crops in the Periyar tract

Madras Agricultural Journal, 1917
If a green manure crop is on a fertile land or the growth of the crop is very thick the land often requires a dressing of a phosphatic manure. This is probably due to the increased nitrogenous and other matter supplied by the green manure crop, requiring a proportionately increased supply of phosphates to enable the crop to take full advantage of the ...

Green Manure Approaches to Crop Production: A Synthesis

Agronomy Journal, 2006
A green manure (GM) is a crop used primarily as a soil amendment and a nutrient source for subsequent crops. Green manure approaches to crop production may improve economic viability, while reducing the environmental impacts of agriculture. However, such approaches are complex because they depend on interactions between the GM, the environment, and ...

Phosphorus Bioavailability following Incorporation of Green Manure Crops

Soil Science Society of America Journal, 2003
Incorporating green manure crops into soil may increase P bioavailability for succeeding crops. We conducted a greenhouse study to evaluate the effects of green manures on biomass and P utilization of a succeeding grain sorghum [ Sorghum bicolor (L.) Moench] crop.

Intercropping green manure crops—effects on rooting patterns

Plant and Soil, 2009
Greater productivity under intercropping has been attributed to the complementary use of environmental resources. However, the rooting pattern of component species under intercropping, which is an important morphological feature considering the complementary uptake of nutrients, has been studied only rarely under field conditions because of inherent ...

Cover and Green Manure Crops for Northwest Nurseries

1984
Green manure crops are planted in Northwest bareroot nurseries primarily to produce organic matter to enrich soil. Available species include grasses, legumes, and brassicas. Legumes are deep rooting, decompose quickly, and can increase soil nitrogen by fixation but require good drainage and well-fertilized soils and can increase soilborne pathogens ...

Leguminous green manures in rice-based cropping systems

1996
The use of soil-improving legumes in rice-based cropping systems has been a topic for debate for many years. The spectrum of opinions ranges from the conclusion that green manure (GM) will never be a significant factor, to the viewpoint that it will be the principle N source for rice in the future.
