The high degree of parasitic variability in Heterodera glycines and its distribution in a wide range of soybean production systems present multiple challenges for management, which necessitate increased understanding of the biology of H. glycines. Soil amendments are being considered either as stand-alone and/or as part of integrated management approaches. A recycled municipal biosolid with nut...
Abstract This study investigated the effects of seaweed extract (SWE) made from brown algae Durvillaea potatorum and Ascophyllum nodosum on plants soil. The application SWE to soil growing tomato showed dual effects. comprehensively improved plant growth (flower clusters, flower number, fruit root length, shoot dry weight, SPAD) increased productivity (yield quality). Similarly, effected biolog...

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
but measurements of total soil-CO2 emissions represent only their sum. Thus, distinguishing among different soil Although soil respiration represents an important C transfer from CO2–producing processes is required if soil respiration terrestrial ecosystems to the atmosphere, the effects of environmental and biological factors on soil respiration rates are not adequately measurements are to be ...
