The nutritive values of non- processed and processed grape pomace with Neurospora sitophila were evaluated. The chemical compositions and physical characteristics of samples were evaluated by laboratory analysis. An in vitro digestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (DOMD) to estimate ...

Recently sorption of organic pollutants, in particular polycyclic aromatic hydrocarbons (PAHs), has received much attention and researchers agree that organic matter (the amount of organic matter and its nature) is the most important factor affecting the sorption, desorption and fate of organic pollutants in soil and sediments. It is well documented that organic matter of soil and sediments is ...

(The effect of different soil properties on arbuscular mycorrhizal colonization of peanuts, sorghum and maize). Arbuscular mycorrhizal fungi (AMF) are important for plant growth since they increase mineral influx. However, symbiosis efficiency is affected by many environmental factors. This study evaluated the effects of different treatments (+/phosphorus; +/liming; +/organic matter; field, san...

Total organic carbon has a major influence on both the chemical and biological processesthat take place in sediments. Algal bloom is one of the organic carbon levels in aquatic ecosystems. In 2009 algal bloom occurred in the Hormozgan province and prolonged for months, which finally setteled down in 2010. In this study the variations of total organic carbon (TOC), organic matter (TOM) and tot...

soil quality is the most suitable index to an assessment of the stability of terrestrial ecosystems, especially agro-ecosystems. to determine the effects of agricultural practices on soil organic matter, species richness and abundance of soil invertebrates, a study was conducted in three regions of razavi and northern khorasan provinces, iran. soil were taken from in each winter wheat field of ...
