Volatilization of ammonia (NH3) from animal manure is a major pathway for nitrogen (N) losses that cause eutrophication, acidification, and other environmental hazards. In this study, the effect of alternative techniques of manure treatment (aeration, separation, addition of peat) and application (broadcast spreading, band spreading, injection, incorporation by harrowing) on NH3 emissions in th...

The long-term applications of different fertilizers (chicken manure, swine and organic fertilizer) on the microorganisms a corn field were investigated. microbial communities during four periods (seedling, three-leaf, filling mature periods) comprehensively studied with molecular biology technology. Results showed that most nutrient contents (organic matter, nitrogen, phosphorus, potassium) lev...

A Field experiment was carried out during Kharif season of 2018 at the research farm in Udai Pratap (Autonomous) College; Varanasi (U.P.), India. The site adjoining to Department Horticulture college. consisted Six treatments comprising combinations recommended doses organic and inorganic manures (FYM, Vermicompost poultry manures). laid a Randomized Complete Block Design (RBD) with six treatme...

Atmospheric emission of the soil fumigant 1,3-dichloropropene (1,3-D) has been associated with the deterioration of air quality in certain fumigation areas. To minimize the environmental impacts of 1,3-D, feasible and cost-effective control strategies are in need of investigation. One approach to reduce emissions is to enhance the surface layer of a soil to degrade 1,3-D. A field study was cond...

A pot experiment was carried out in 2019 the net house of Department Soil, Water and Environment, University Dhaka, to evaluate growth yield Jute plants (Corchorus capsularies L.) by applying different types organic manures. Eight manures viz. ACI, BGF-1, Mazim, Vermicompost, Shufola, GTS, Green Poultry were collected from local market. The set up following a completely randomized design (CRD) ...

• Short term fallows enhance productivity, improve soil fertility and serve dual purpose in crop-livestock systems. Green manuring increased wheat grain yield by 18–26 % over mineral fertilizers. Root biomass of green manures alone subsequent crop 25 %. improved water, pH, organic carbon nutrients. Residual effect compensates 33 N demands wheat. Soil depletion is a major constraint smallholder ...
