Forests are an important economic source for human and have key role in nutrient cycle, hydrology and ecosystem performance, any interference in this vital ecosystem causes to damage to forests. Mechanical logging and road construction in forest areas have led to much soil compaction. Soil physical and chemical properties were studied in parts of road and non-road in the Darabkola forest of Ira...

Sterilized soils are commonly used for the study of xenobiotic sorption and as an abiotic control in biodegradation experiments. They are also used for the chemical study of nitrogen and carbon cycle processes and the elimination of the biological factors. In this research the effects of different soil sterilization methods such as autoclaving, fumigating and exposure to ultraviolet and microwa...

plants have noticeable effects on soil resources distribution and its biochemical processes, and organic materials are naturally much more in the understory soil as compared to open areas. vegetation as one of the soil formation factors is not always an independent variable, so that the soil and vegetation can have interaction. the present study was conducted to investigate the effects of hedys...

Enclosure and Acacia shade availability to plants are basic variable in arid and semi-arid rangelands. the aim of this study was investigation the impact of patch enclosure and Acacia shade using four treatments which are Inside Enclosure Under Acacia shade (IEUA), Inside Enclosure Without Acacia shade (IEWA), Outside Enclosure Under Acacia shade (OEUA) and Outside Enclosure W...

abstract different definitions have been proposed for soil quality. various soil properties have been suggetsted as soil quality indices by researchers. this research was conducted to study the relationship between slope of retention curve at its inflection point (s index) and other soil physical quality indices, because the reserches between s index and soil physical properties are little. thi...

the fire as one of the ecological factor has positive or negative effects on ecosystems components. therefore, this study was evaluated the effect of fire on some soil physico-chemical properties in winter rangelands of behshahr. so that two burned sites were selected in rangelands and changed rangelands to wheat and barley with two control areas (unburned) in each of them. the soil sampling wa...

assessment of soil quality is one of the most useful tools for evaluation the soil management condition and different land uses. quantity indices of soil quality are most suitable methods for determination and comparison of soils quality. in this study soil quality indices and selection methods of effective soil properties were compared for evaluating the soil quality in different land uses. se...

Pinus massoniana forests bordering South China are often affected by wildfires. Fires cause major changes in soil properties in many forest types but little is known about the effects of fire on soil properties in these P. massoniana forests. Such knowledge is important for providing a comprehensive understanding of wildfire effects on soil patterns and for planning appropriate long-term forest...
