Current study was carried out with aim to evaluate the effect of pressurized irrigation methods and furrow irrigation method with municipal effluent on distribution of salinity and moisture in the soil profile. The experimental study was designed by split plot layout with three irrigation methods including furrow, surface drip (SD) irrigation and subsurface drip irrigation (SSD) and two water q...
Grazing by livestock can affect plant biodiversity and topsoil functions. However, experimental evidence on whether these impacts are limited to the or penetrate into deep layers (via changes in soil environment resource locations) of is lacking, especially for microbial biomass diversity. Here, we used paired grazed ungrazed (fenced) plots at 10 locations across Mongolian Plateau investigate h...

Increasing soil organic carbon (SOC) storage is one of the promising solutions to mitigate climate change. Fast-growing trees are a potential tool in this context as they rapidly accumulate C their biomass and could transfer more matter (OM) into soil. However, relationship between aboveground productivity SOC remains poorly understood. Five clones with different growth rates were selected from...
Deforestation leads to the deterioration of soil fertility which occurs rapidly under tropical climates. Forest rehabilitation is one of the approaches to restore soil fertility and increase the productivity of degraded areas. The objective of this study was to evaluate and compare soil biological properties under enrichment planting and secondary forests at Tapah Hill Forest Reserve, Perak aft...
Inductively coupled Plasma- Atomic Emmision Spectroscopy (ICPE-AES) was applied for the analysis of soil Fallujah city. The samples were taken from 50 different locations in city and at depths 20, 40 60 cm. No Cd ions detected soil. Yet significant contamination dtected with elements, Pb, Cr, Ni, Co, Zn Cu. Fe concentration value found to be less than international average value. results showed...
Methods of seedbed preparation affect establishment, growth and yield of crops via manipulating physical and chemical properties of soil. These effects on wheat-mungbean double-cropping have not been studied in Isfahan. Therefore, the influences of various seedbed preparation methods on soil physical properties and nutrients content and on establishment of mungbean (experimental line 1-61-16) w...
We investigated the effects of seed burial depth and soil water content on seedling emergence and growth of Ulmus pumila var. sabulosa (sandy elm), an important native tree species distributed over the European-Asian steppe. Experimental sand burial depths in the soil were 0.5, 1.0, 1.5, 2.0 and 2.5 cm, and soil water contents were 4%, 8%, 12% and 16% of field capacity. All two-way ANOVA (five ...
