Knowledge of the spatial dependency of soil properties, sensitive to grazing systems, is important from an ecosystem protection point of view. In the current study, geostatistical methods and fractal concepts have been used in order to characterize the impact of long-term grazing exclusion on the spatial variability of some soil chemical parameters including organic matter, total nitrogen, avai...

  Abstract   Background: Today, vermicompost production process as one of the very good procedures in terms of economic,health, and environmental sustainability to stabilize the organic waste is discussed. The aim of this study is vermicompost production from urban waste by earthworm (Eisenia Fetida) in Household-scale.   Methods: In this experimental study, plastic tank of vermicompost product...

In order to investigate effect of nitrogen fertilizer on yield and quality of three forage sorghum cultivars under Guilan climatological conditions a field study was conducted in 2010 cropping season at Rasht. A randomized complete block design with factorial arrangement with three replications was used. Treatment consisted of four levels of nitrogen fertilizer (0, 50, 100 and 150 kg N ha-1 fro...

  This experiment was conducted to determine nitrogen fractions and ruminal dry matter and protein degradability of raw or heated (roasted or extruded) soybean seed. Samples were incubated for 2, 4, 8, 16, 24 and 48 h in the rumen of 4 cannulated Kurdish male lambs (50 ± 3 kg BW) . N itrogen fractions of samples were measured by chemical methods. Results showed that extruding decreased non-prot...

Agroforestry is one of the sustainable agricultural aspects in which the perennial woody plants grow in selective method with annual plants, domestic or both. This experiment was conducted to evaluate the effects of different sowing densities and nitrogen fertilizer rates on quantitative and qualitative characters of corn forage yield as well as weed population in an agroforestry system with or...

The objective of this study was to evaluate the characteristics of millet silage prepared in laboratorial mini silos and to determine the effects of additives on its fermentation quality. Whole millet (Panicum milliaceum) was harvested at milk and soft-dough stages of maturity, left untreated or treated with ground barely, molasses, formic acid, lactic acid producing bacteria, and combination o...
