Green Manuring in Crop Production

Journal of Plant Nutrition, 2007
ABSTRACT The positive role of green manuring in crop production has been known since ancient time. Importance of this soil ameliorating practice is increasing in recent years because of high cost of chemical fertilizers, increased risk of environmental pollution, and need of sustainable cropping systems.

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.

Cover crops, green manures and herbal leys.

2022
Abstract This chapter discusses cover crops, green manures and herbal leys. Cover crops comprise a range of plant species, preferably a mix that includes legumes, brassicas and grasses. Green manures have an emphasis on adding organic matter and nitrogen to the soil, especially where there are no animals to add manure.

Cover/Green Manure Crops

2016
For any annual cropping system to be sustainable, the cover/green manure crops can be considered as the backbone. They are important in sustainable farming because of nitrogen fixation, nutrient enhancement, enhancement of organic matter, improvement of soil structure, rooting action, soil and water conservation, soil microbial activity, and weed ...

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 ...

Cover/Green Manure Cropping

2017
The cover/green manure crops can be considered as the backbone for any annual cropping system to be sustainable. They are responsible for sustainable farming because of enhancement of organic matter, improvement of soil structure, nitrogen fixation, nutrient enhancement, rooting action, soil and water conservation, soil microbial activity, and pest ...

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 ...

Ammonia volatilization from crop residues and frozen green manure crops

Atmospheric Environment, 2010
Abstract Agricultural systems can lose substantial amounts of nitrogen (N). To protect the environment, the European Union (EU) has adopted several directives that set goals to limit N losses. National Emission Ceilings (NEC) are prescribed in the NEC directive for nitrogen oxides and ammonia.
