A Review of Potassium-Rich Crop Residues Used as Organic Matter Amendments in Tree Crop Agroecosystems

Crop management factors influencing yield and quality of crop residues

In the semi-arid tropics, over two-third’s of the world’s people depend on agriculture within which livestock play a major role in building rural livelihoods. Crop residues (fodder/stover) are important feed resources for ruminants. This review was undertaken with the objective of improving understanding of the role of various crop management factors in affecting the productivity and quality of...

Use of crop residues as animal feeds in developing countries

Development and application of modem technology for upgrading straw in Europe during the 1970's has stimulated intense interest in developing countries. Since 1980, twenty four international workshops have been held in Africa and Asia to consider research and development on crop residues as feed, with emphasis on improving their intake and digestibility in ruminants by treatment with ammonia ge...

Biodiversity in Agroecosystems: Importance of Non-crop Habitats

Evaluation of Post-Harvest Organic Carbon Amendments as a Strategy to Minimize Nitrogen Losses in Cole Crop Production

Cole crops (Brassica vegetables) can pose a significant risk for N losses during the post-harvest period due to substantial amounts of readily mineralizable N in crop residues. Amending the soil with organic C has the potential to immobilize N and thereby reduce the risk for N losses. Four field trials were conducted to determine the effects of organic C amendments (OCA) on N dynamics and sprin...

Weed Management in Organic Horticulture by Cover Crop in Iran

Objective: Citrus (Citrus reticulata) is one of the most important horticultural plant in Iran and weed management throuth ecological methods such as cover crop is a proper option in orchard management practices. Methods: The experiment was designed as a split plot on the base of complete randomized block design with four replications in Mazandaran Province, Sari, Voushka county from 2...
