Saline water is widely distributed in the arid environment and sometimes represents only source of irrigation to restore reconstruct vegetation. However, effects saline on bacterial diversity fertility level aeolian sandy soil are not well understood. In this study, we investigated a vegetation belt along Tarim Desert Highway that has been constructed as windbreak consists desert shrubs was irr...

the effect of exclosure on the changes of vegetation cover of rangelands of ahmad-abad region located in zanjan province has been studied during 2002 to 2006. three transects comprises of 60 fixed quadrate were establish within exclosure area and outside as well. the changes of vegetation cover were studied to made comparison between the changes of manipulated factors and soil elements using t ...

One of the influential tools concerning the rangeland and vegetation sciences isthe technology of remote sensing and satellite data. Satellite data have played essentialroles in preparing the needed information for studying the vegetation. Vegetation has beenwidely recognized as one of the best indicators for determining the land conditions. Usingvegetation indices is one of the techniques of r...

Permanent gullies are a serious type of soil erosion. A special permanent gully, called “Benggang” severly affects agricultural production in hilly areas. To reveal the influence Benggang erosion on granitic restoration and fertility, we selected three stages (active, semi-stable stable) recovery subtropical granite region, corresponding samples were collected to analyze spatial variation physi...

Forest ecosystems are among the largest terrestrial carbon reservoirs on our planet earth thus playing a vital role in global carbon cycle. Presently, remote sensing techniques provide proper estimates of forest biomass and quantify carbon stocks. The present study has explored Landsat-8 sensor product and evaluated its application in biomass mapping and estimation. The specific objectives were...

Soil fertility affects crop yield and quality. A quick, accurate evaluation of soil is crucial for agricultural production. Few satellite image-based studies have quantified during the growth period. Therefore, this study proposes a new approach to quantitative fertility. Firstly, optimal spectral variables were selected using integration an extreme gradient boosting (XGBoost) algorithm with va...

In the Brigalow Belt bioregion of Australia, clearing brigalow (Acacia harpophylla) scrub vegetation for agriculture has altered nutrient cycling over millions hectares. order to quantify effect this and land use change on soil fertility, Catchment Study commenced in 1965. Initial burning resulted a temporary increase mineral nitrogen, total available phosphorus, exchangeable potassium sulfur s...
