Soil correction is one of the ways in agriculture lands development. The sodic ion alongside salin vocalizes the salin-sodic soil and cause divulge in plants growth. So necessary coure of action for the Soil correction by physical and chemical ways such as usage of calsium on the leaching is inevitable. In this study, area soils are digged from deep profiles of 0-20, 20-40, 40-60, 60-80 and 80-...

Soil biochemical properties and microbial communities are usually considered as important indicators of soil health because of their association with plant nutrition. In this study, we investigated the impact of long-term application of bioorganic fertilizer (BOF) on soil biochemical properties and microbial communities in the apple orchard soil of the Loess Plateau. The experiment included thr...

the effects of soil tillage methods and residue management were studied at miandoab agriculure station during 2003-2005. the experiment design was split block with the main plots devoted to residual management strategies (burning residue, crushing residue by disk, no treatment). subplots were tillage methods (moldboard plowing to 20-25 cm in fall, moldboard plowing to 20-25 cm in spring, moldbo...

rehabilitation of arid and semi-arid regions by tolerant native plant cover is a primary concern to create a sustainable balanced ecosystem. thus, the existing plant species of the region should be recognized together with a comprehensive survey and study of the environmental factors such as climate and soil conditions which affect the establishment of these plant species. this paper attempts t...

The depth of sampling is an important factor for evaluating soil stability. The objective of this study was to test soil aggregate particle-size fractions and soil organic carbon (SOC) in water-stable aggregate by vegetation restoration through 0–60 cm soil profile. We collected soil samples in 30 years old Robinia psendoacacia (Rr); Platycladus orientalis (Po); Pinus tabulaeformis (Pt); abando...
