consumption of organic manures such as vermicompost and spent mushroom compost in a system based on organic agriculture beside to maintenance soil health improvement and yield of medicinal plant spearmint. therefore, an completely randomized design experiment with four replication on spearmint (mentha spicata l )was conducted in horticultural department of mohaghegh ardabili university. experim...

Changes in physicochemical characteristics, chemical structures and maturity of swine, cattle and chicken manures and composts during 70-day composting without addition of bulking agents were investigated. Physicochemical characteristics were measured by routine analyses and chemical structures by solid-state 13C NMR and FT-IR. Three manures were of distinct properties. Their changes in physico...

Manure water-extractable phosphorus (WEP) data are used in indices and models to assess P transport in runoff. Methods to measure WEP vary widely, often without understanding the effect on howmuch P is extracted.We conductedwater extractions on five dairy, swine, and poultry manures to assess single and sequential extractions, drying manures, solution to solid (cm g) extraction ratios, andPdete...

Ironically, scientists one-half century Groundwater has become increasingly degraded by NO3, and this ago devoted much research emphasis to providing farmdegradation has been partially attributed to the use of commercial inorganic N fertilizers. Conversion from conventional fertilizer maners information on the beneficial use of ...

Consumers are placing increasing importance on an environmentally friendly way of food production and turning to organically produced fruit vegetables. Organic farming rejects the use synthetic pesticides or fertilisers, growth promoters, antibiotics, transgenic organisms. However, manures that replace fertilisers is associated with a risk contamination produce pathogenic microorganisms. There ...
