Excessive use of nitrogen fertilizer and inappropriate fertilization designs have negative results in agricultural ecosystems, such as considerable losses through dioxide (NO2) soil leaching ammonia NH3 volatilization. In addition, climate change, with rising summer temperatures reduced precipitation, leads to production declines water shortages the soil. This review aims highlight characterist...

the use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. one of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. this research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...

Stressors including regional climate change, economic development effects upon land use and an increasing demand for food production have resulted in significant impacts on the dryland ecosystems in the East Asia (DEA) region. Ecosystem services, such as its provisional services in providing forage for grazing as well as its functional services in regulating water and carbon fluxes, have been s...

Drylands typically have distinctive vegetative patterns that reflect the underlying physical landscape. We use a geopedological classification to organize the landscape into five categories from broad scale to fine scale: (1) physiographic divisions which describe regional topography, such as mountains and basin floors; (2) regolith type which identifies residuum versus transported sediments; (...

Land-cover change is regarded as the most important global change affecting ecological systems (Vitousek, 1994). Natural landscapes – i.e. those largely unaffected or hardly affected by human activities – are being rapidly transformed into urban and farmland landscapes throughout the world (Foley et al., 2005; Feranec et al., 2010; López and Sierra, 2010). As the characteristics of land-cover h...

in recent years, changes in catchments water balance due to land use management have become the main concern of water resources authorities in iran. due to rapid population growth and land use changes, especially construction of taleghan dam, taleghan catchment has undergone rapid changes such as urban development, declining of rangelands, and deterioration of environment and erosion of soil re...

This research aimed to estimate the splash erosion and its evolution during first months in specific land uses after a forest fire. The study area was located Congosto (North-West Spain), margins of Spanish drylands, wildfire occurred May 2012, which burned 15.56 ha scrubland Pinus reforestation. Two different were selected compared control areas: i) pine forest; and, scrublands. Rainfall inten...
