Acid mine drainage (AMD) is one of the problems arising from mining activities. formed due to oxidation sulfide minerals such as pyrite (FeS2) by water and oxygen. Alternative management AMD in a sustainable eco-friendly way constructed wetland. Therefore, this study was conducted determine type composition potential organic matter that can improve quality. The consisted three stages: screening...

The Saffron Yield Estimation Model (SYEM) was modified for salinity conditions, cowmanure application and planting methods using two-year experiments data in Badjgah region ofIran. A split-split plot arrangement was conducted in complete randomized block design duringtwo years with irrigation water salinity levels (0.45 (fresh water, S1), 1.0 (S2), 2.0 (S3) and 3.0(S4) dS m-1) as the main plot,...

The biogas fermentation from animal manure and organic waste was investigated with a comparison percentage of raw material used inside the digester anaerobic digestion process. Animal consists cow dung chicken manure, while tofu liquid cabbage waste. This study batch process that operated at 55 °C incubator temperature for 90 days. results experimental data were predicted modified Gompertz mode...

The objective of the present study is to investigate the effects of irrigation water salinity,cow manure levels and different planting methods on saffron quality compounds includingcrocin (coloring strength), picrocrocin (bitterness) and safranal (aromatic strength). A split-splitplot arrangement was conducted in complete randomized block design with irrigation watersalinity levels (0.45 (fresh...

in recent years, in order to enhance the health of agroecosystems, concerns on ecological inputs especially to produce medicinal plants, has been increased. in order to evaluate the effects of winter cover crops on pgprs activities and soil nitrogen content in simultaneous application of organic manures and biological fertilizer in a low input production system of cucurbita pepo under minimum t...
