compost is one of the strategies of house hold solid wastes management that is used to decrease the volume and weight of wastes, odor and leach ate dispersion, resource recycles and decreasing disposal expenses. in order to observe environmental regulations in the frame of adaptation development projects with environmental concerns, assessment of environmental impact of composting plants has be...

agricultural droughts are droughts that affect the crop production or the ecology of a region. ravar city that is located in margin of desert and the north of kerman province is one of these areas. due to the existence of enough underground water that entrance to desert and high evaporation to improving agricultural and cultivar activities, it needed to study the construction of underground dam...

salinity tolerance is one of the most important affecting factors on agricultural production in arid and semi-arid areas. in order to study the effects of saline and fresh water irrigation with application of organic and npk fertilizers on cumin, a split plot experiment based on randomized complete block design was carried out with three replications during 2011 and 2012, at the research farm o...

the aim of this research was to study the relationships between presence of plant species and environmental factors in garizat rangelands of yazd province and providing their predictive habitat models. after delimitation of the study area, sampling was performed using randomized-systematic method. accordingly, vegetation data including presence and cover percentage were determined in each quadr...

Irrigated agricultural lands are prone to salinity problems which may imperil horticultural crops by reducing growth, yield and even qualitative traits. Eco-friendly approaches such as biostimulant application in particular protein hydrolysates from vegetal origin implemented mitigate stress effects on crops. For this reason, a greenhouse experiment spinach irrigated with increasing concentrati...

Ground-based measurements of meteorological parameters and water-soluble organic carbon in the gas(WSOCg) and particle (WSOCp) phases were carried out in Atlanta, Georgia, from May to September 2007. Fourteen separate events were observed throughout the summer in which WSOCp and water vapor concentrations were highly correlated (average WSOCp-water vapor r = 0.92); however, for the entire summe...

It has long been known that chloride-dominated saline ground waters occur at depth in the UK, not only beneath the sea but also onshore at depths of a few hundred metres. In a few places in northern England, these saline waters discharge naturally at surface in the form of springs. In recent years, however, these saline ground waters have come to be regarded as resources: as potential geotherma...
