The non-target effects of Amistar (azoxystrobin) and Score (difenoconazole) were studied in terms of changes in the soil microbial populations, soil respiration and activity of soil enzymes. Both the fungicides significantly reduced the fungal population in the soils even at the lowest concentration used (0.44 g. (a.i.) g soil) and totally eliminated it at the recommended dose for field applica...
understanding the relationship between soil and plant is essential for reclamation of degraded lands. in order to investigate the relationship between atriplex halimus density with carbon sequestration the rangeland of incheborun was studied. soil samples were collected randomly by auger in the depth of 0-30 cm of the soil profile in three different plant densities (400 stand per hectare) with ...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
In order to achieve a sustainable management of land resources and to improve land quality, quantitative assessment of effective factors and soil quality indicators are required. The aim of this study was to evaluate variability of selected soil quality attributes in central Zagros affected by such factors as region, land use and management practices. Twelve sites were selected in three provinc...
BACKGROUND Biological soil crusts are common components of desert ecosystem; they cover ground surface and interact with topsoil that contribute to desertification control and degraded land restoration in arid and semiarid regions. METHODOLOGY/PRINCIPAL FINDINGS To distinguish the changes in topsoil affected by biological soil crusts, we compared topsoil properties across three types of succe...
The forest soils are the key parts of the Earth system that are globally degraded through anthrop induced deforestation, mainly converting to other landuses. The present study was conducted in Gazafolya village located in Merek watershed, Kermanshah, Iran, in which the soil quality of the forest and converted forest (rainfed lands) with the same topographic and geologic conditions were compared...
epizoochory and endozoochory are well-known mechanisms by which seeds are dispersed by animals. since, livestock gather around the watering-points to rest and drink, we expected to find that seeds would be frequently moved to the areas surrounding watering-points, resulting a higher soil seed density (and diversity) closest to the water. we investigated this issue by assessing soil seed bank de...

Laboratory experiments investigated the comparative degradation of six organophosphorus insecticides in soil as affected by enhanced microbial degradation. The degradation rates and product distributions of chlorpyrifos, fonofos, ethoprop, terbufos, and phorate were not dramatically altered in soils containing microbial populations adapted to rapidly degrade isofenphos. An Arthrobacter sp. isol...
