Reducing chemical use for suppressing internal and external parasites of livestock is essential for protecting environmental health. Although plant condensed tannins are known to suppress gastro-intestinal parasites in small ruminants, no research on the effects of tannins on external arthropod populations such as the house fly, Musca domestica L., have been conducted. We examined the impact of...

The aim of this research study was to analyse the effect of applying inverted phase fermentation (IPF) prior to the anaerobic digestion of cattle manure and sewage sludge. IPF promotes the endogenous bacteria present in waste and hence enzymatic hydrolysis, producing a solid-liquid separation. The clarified bottom layer or liquid phase (LP, 70% volume in manure and 65% in sludge), and the thick...

current research was aimed to study the effect of soil different treatments on seed germination and seedling survival of pinus brutia ten. seedling in nursery of koloudeh, located in amol city. seeds in plastic pots were sown at four different soil treatments including: (a) nursery soil (control), (b) control soil: cattle manure (5:1), (c) control soil: decomposited litter (5:1), (d) control so...

iron is an essential microelement for plant growth. low content of organic matter and excess application of phosphate fertilizer in soils can be affected on availability of iron. in this study the effect of iron, phosphorus and organic matter on growth and iron uptake of mays was evaluated. a greenhouse experiment was conducted with two levels of cattle manure (0 and 1 %), three levels of phosp...
