The ability to predict manure nitrogen mineralization is essential for optimizing crop growth while preventing N losses to the environment. However, estimating mineralizable manure N is problematic because of the wide variety of organic manure N forms, as well as the lack of a rapid standardized method. Fourier-transformed infrared spectroscopy (FT-IR) is a promising technology, since it can de...

abstract by increasing the world population and more need to supply food, farmers attend to use of chemical fertilizers, organic manures and pesticides. also, applications of these agents without attention to their side effects, cause more problems to human health and environment. nitrate is one of the most important elements of organic manures, which leach through soil to surface and ground wa...

The fate of two strains of Listeria monocytogenes and their ability to become viable but non-culturable (VBNC) was investigated in microcosms containing piggery effluents (two raw manures and two biologically treated manures) stored for 2 months at 8 and 20°C. Levels of L. monocytogenes were estimated using the culture method, qPCR, and propidium monoazide treatment combined with qPCR (qPCRPMA). ...

Manure not only supplies many nutrients for crop production, but it is also a valuable source for increasing soil organic matter content and improving soil structure. To increase organic manure content as well as improve the wheat production adding plant residues and livestock to soil is necessary. The experiment was conducted in Shavoor Research Station to determine seed yield and soil physica...

in order to develop the high intensive agriculture, more chemical fertilizers are applied to the soil that resulting in soil degradation and environment deterioration. application of organic manure is an important approach for maintaining and improving the soil fertility and increasing fertilizer use efficiency. therefore, in order to evaluate the effect of organic manures and chemical fertiliz...

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...
