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). ...

Computer models are a rapid, inexpensive way to identify agricultural areas with a high potential for P loss, but most models poorly simulate dissolved P release from surface-applied manures to runoff. We developed a simple approach to predict dissolved P release from manures based on observed trends in laboratory extraction of P in dairy, poultry, and swine manures with water over different wa...

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...


 A pot experiment was carried out to check the impact of different organic manures and inorganic fertilizers on growth yield turnip, at Horticulture Departmental experimental area, Faculty Agriculture, Gomal University, D.I. Khan, during 2012-13. The laid in RCD with seven treatments replicated three times. Treatments contained control (no fertilizer added), FYM @ 25 t/hec, Poultry manure...

Nutrient use efficiency is reported as a strong indicator of the buildup soil nutrient status for nutritional security crops through an integrated management approach under rice-wheat system. The data revealed that application manures and fertilizers maximum organic carbon (0.39%) in treatment receiving 100% recommended dose (RDF) + farmyard manure lowering pH to 6.39. available N (360.8 kg ha?...

The objective of this research was to evaluate the impact of organic sources (animal manures vs. plant residues at the rate of 10 t ha-1 each) on the productivity of hybrid rice (Oryza sativa L.) production under different levels of phosphorus (0, 30, 60, and 90 kg P ha-1) fertilization. Two separate field experiments were conducted. In experiment (1), impact of three animal manures sources (ca...

Livestock manures are an important resource in sustainable and organic crop production. This publication addresses the problems and challenges of using both raw and composted manures and discusses some of the solutions. It also deals with guano, a similar material. Manures for Organic

A pot culture experiment was conducted at the Department of Agronomy, Madras Veterinary College, Chennai, during rabi season 2019 - 2020 to study influence organic manures and synthetic fertilizers on nutrient uptake green fodder yield maize (Zea mays L.). An laid out with two factors three replications. Four manure treatments in main-plots viz., no manure, farm yard (25 t ha-1), vermicompost (...
