In this study, the nutritive values of treated Walnut hull by Neurospora sitophila were evaluated. The chemical composition of samples was evaluated by laboratory analysis.In vitrodigestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (DOMD) to estimate the metabolizable energy (ME) content oftreat...

throughout the present study, similar horizons (a, ab and b1) from deciduous forest, coniferous forest and rangeland types of land uses were selected, and the percentage of water stable aggregates in them measured. in each class of stable aggregate at the horizon a, free light fraction, free-particulate organic matter, intra-aggregate of particle organic mather (pom), and clay + silt complexes ...

24-hour samples of pm1 (submicron particles, aerodynamic diameters ≤1 μm) and pm2.5(fine particles, aerodynamic diameters ≤ 2.5 μm) were collected at a quasi-rural area in racibórz (1 january-30 june 2011). the samples were analysed for carbon (organic and elemental), water-soluble ions (na+,nh4 +, k+, mg2+, ca2+, cl-, no3 -, so4 2-) and concentrations of 21 elements with a carbon analyser (sun...

A combination of high performance size exclusion chromatography with organic carbon detector and ultraviolet detector coupled with peak-fitting technique and fluorescence excitation-emission matrix spectrometry applied fluorescence regional integration method was conducted to determine the characteristics of organic matter during nitrification. The batch scale of bionet nitrification without or...

this research was conducted to study the effect of land use change on some physical fractionation component of organic matter and some of its quality factors. therefore, two uncultivated and cultivated (such as rotational cropping and sugarcane) were selected in khuzestan province. disturbed and undisturbed soils were sampled from 0-30 and 30-60 cm depths. total n, oc, dispersible clay (dc), ag...

this study was conducted to investigate the impact of land use change on some of carbon components in safashahr area, fars province. four land uses (destroyed rangeland, agricultural land, new and old apple orchard) were selected. sampling was done randomly from two depths (0-20 and 20-50 cm) of each land use. particulate organic matter (pom) and extractable carbohydrate by hot water were measu...
