 Study Design: The experiment set up a Fisher block design, with four treatments three replications.
 Place Duration Study: trials were ...

Many studies on methane (CH4) and nitrous oxide (N2O) emissions from livestock industries have revealed that livestock production directly contributes to greenhouse gas (GHG) emissions through enteric fermentation and manure management, which causes negative impacts on animal environment sustainability. In the present study, three essential values for GHG emission were measured; i.e., i) maximu...

in order to understand the effect of plant density and different fertilizers on sesame (sesamum indicum l.) production, an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications. the experimental treatments were fertilizers in four levels (cow manure (30 t.ha-1), municipal compost (30 t.ha-1), chemical fertilizer (250 kg ammonium ...

In the European Union, groundwater should contain less than 50 mg of nitrate/L. Individual countries have developed alternative strategies for phosphorus (P). In The Netherlands, regulations based on P limited the amount of manure applied per hectare. A more balanced P supply to the land has been achieved by transport of manure from surplus to deficit regions. Costs of processing of manure to p...

Nitrate nitrogen losses through subsurface drainage and crop yield are determined by multiple climatic and management variables. The combined and interactive effects of these variables, however, are poorly understood. Our objective is to predict crop yield, nitrate concentration, drainage volume, and nitrate loss in subsurface drainage from a corn (Zea mays L.) and soybean (Glycine max (L.) Mer...

in order to evaluate the response of quantitative and qualitative characteristics of the isabgol (plantago ovata frosk.) medicinal plant to separate and combined application of urea and biofertilizer an experiment was conducted in a randomized complete block design at the research farm of shahrekord university in 2011. the experimental treatments consisted of control (no urea and biological fer...

proach, 12 to 63% of dairy manure N may be taken up by corn during the first growing season after application Current estimates of dairy manure nitrogen availability to crops (Motavalli et al., 1989; Klausner et al., 1994). Nutrient are based on indirect measures and vary greatly. The objective of this study was to differentially label dairy manure N components with the availability in the seco...

The residue levels of selected fluoroquinolones, sulfonamides and tetracyclines in 143 animal dung samples collected in 2007 from large-scale livestock and poultry feedlots in 8 provinces were determined by using ultrasonic extraction and liquid chromatography. Recoveries from spiked pig dung samples (spike level=1mg/kg) ranged from 73.9 to 102.0% for fluoroquinolones, from 81.6 to 92.3% for su...
