converting the native rangelands to simplified agronomic communities causessome changes in soil carbon, nitrogen and phosphorus. establishing of perennial plantcommunities on formerly cultivated rangelands is expected to stabilize soil properties andincrease the amount of c, n, p stored in rangeland soils, but there is little information on whatplant communities are the most effective for impro...

lead (pb) is one of the most hazardous heavy metal that caused serious problems for ecosystem at recent years. in this study, the effect of pb on seed germination, incipient growth and antioxidant enzymes of six common used turfgrasses was investigated. the results showed that after implementation of different concentrations (0, 1000, 2000 and 3000 µm) of pb, agropyron elongatum exhibited the h...

Post-disturbance rangeland restoration efforts are often thwarted due to soil moisture deficits. Superabsorbent polymers (SAPs) absorb hundreds of times their weight in water, increasing when the SAP is mixed with soil. The objective this study was evaluate banded SAPs under surface increase plant available water and thus seedling establishment for perennial species during efforts. Five glassho...
