abstract unbalance using of chemical fertilizers cause decline the soil quality and fertility, environmental pollution and specially soil and water resources pollution. the use of animal manure is a replacement to chemical fertilizers. therefore, recognizing of demographic, technical-extensional and agronomic affect on farmer's decision making process to use of animal manure will have important...

  The main purpose of this research is review of principles, concepts, problems and solutions of soil ethic. In this research by descriptive method and Delphi technique was used for identifying soil ethical concepts, soil ethical principles, problems and difficulties of soil ethics in Iran and al around the world and suggestions for improvement of soil ethics in Iran. The population of this re...

Due to rapid industrialization and urbanization, environmental pollution has become a major concern in developing countries; therefore, the main objective of the current study is to determine heavy metal contents of Pb, and Ni for 42 topsoil samples, collected from 14 green spaces along the 1st and 2nd ring roads in Hamedan City in 2016. For this purpose, after determining some chemical propert...

As a communication link between suburban and urban roads, terminals prevent buses from entering the cities, thus, they play an important role in improving traffic flow, reducing urban environmental pollution. Clearly, proximity of te rminals to cities will bring about environmental pollution in different forms (soil, water, air and wastewater). The current study tries to investigate the environ...

Soils around mining sites play a significant role in the transport and control of heavy metals in the environment. Therefore, understanding the adsorption properties of soil is essential in solving pollution problems. The objective of this paper was to study Zn(II) adsorption onto Sarcheshmeh copper mine soils. The adsorption isotherms of Zn(II) were studied. The Langmuir isotherm indicated an ...

generally heavy metals exist in all soils, but soil pollution is rising by time due to human activities. soils in the proximity of mines are more pruning to pollution of heavy metals due to mine exploring and excavation. this research was carried out to evaluate the soil pollution of sepahanshahr suburb with pb, zn and cd. during a field work campaign 100 soil samples were selected randomly fro...
