In this investigation, the effects of enclosure, restal delayed grazing and continued grazing treatments on the production rate and vegetation cover were studied. Study area was SadrAbad pasture. After selecting three bands (1+1+1=3 hectare area) as three treatments in the restricted and non restricted area, they were transected to three transects. Then plots (1×2m2 ) […]
Since Renaissance, the natural ecosystems have fallen into a complete state of disarray due to the rise in the amount of carbon dioxide. Soil, the unsparing stuff, is one of the major sources of carbon storage, and plays a paramount role in the global equilibrium of carbon as well as carbon sequestration. Given that Iran […]
The first motive for the determination and evaluation of an energy production system is the need to change. Such system is dynamic in nature and is influenced by many factors such as age and physiological status of individual sheep or goat, quantity and quality of available feed and environment including the management systems. Traditional pastoral […]
Assessing the quality of groundwater is important to ensure the sustainable safe use of these resources. However, describing the overall water quality condition is difficult due to the spatial variability of multiple contaminants and the wide range of indicators (chemical, physical and biological) that could be measured. Therefore, in this case study, some water quality […]
The isotopic documents of lake deposition are suitable potential means for studying the intercontinental, environmental and climatic conditions. In order to study the environmental and climatic conditions of Parishan area in Fars province in Holocene, a Core was taken with the length of 2m from the Parishan lake sediment. From this core, kernel time series […]
Grazing management plays an important role in the continuous and economic utilization of pastures. Proper grazing management is a main factor for the accumulation of plant litter which reduces soil erosion and increase the soil permeability to keep more moisture in the soil. In current study, the effect of three different grazing intensities (low, moderate […]
For the successful tree establishment, an evaluation of land suitability is necessary. In this paper, we demonstrate how to implement fuzzy classification of land suitability in a GIS environment for afforestation with Juglans regia in Gharnaveh Watershed of Golestan Province in Iran. Juglans regia is one of the most important agro-forestry species in many rural […]
There are more than 750 counties in 13 provinces and autonomous regions constituting 30% of China lands which are facing serious problem of desertification. These areas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part of Northeast China, North central china and most of northwest china. Biological methods are the […]
Seeds of 200 accessions of alfalfa (Medicago sativa L.) were provided from Iranian natural resource gene bank and were sown as drilled plot using alpha designs/unreplicated with 2 repeated entries within all of 10 blocks under dry land farming system in agricultural research center of Hamadan, Iran during 2009 to 2010. The data were collected […]
