Effect of Copper and Organic Matter on Copper Distribution in Two Calcareous Soils
Copper is an essential microelement for plants. Soil organic matter content and copper (Cu) are low in most cultivated soils of Iran. Sequential extraction has been used as a suitable method for identification of chemical forms of heavy metals...
Effect of tannery wastes and biochar on soil chemical and physicochemical properties and growth traits of radish
Tannery wastes can be used in soil as organic manure. The aim of this research was to study the effects of tannery wastes (before a chromium addition step) and biochar on soil chemical and physicochemical properties and ...

Effect of Organic Matter and Salinity on Ethylenediaminetetraacetic Acid-Extractable and Solution Species of Cadmium and Lead in Three Agricultural Soils
Abstract: A study was conducted to investigate the chemical speciation of added cadmium (Cd) and lead (Pb) and their availability as influenced by fresh organic matter (OM) and sodium chloride (NaCl) in three agricultural soils. The soils were...
Alleviating the Salt Stress Effects in Salvia splendens by Humic Acid Application
Salt stress is a serious problem in urban landscape of arid and semi arid regions. To overcome the adverse impacts of salinity, the application of organic matter and plant nutrients in the growth media for improving of plant growth is essential...
Effects of Global Warming on Decomposition of Soil Organic Matter: A Simulation Study
Higher temperatures could increase the rate of microbial decomposition of organic matter, adversely affecting soil fertility and increasing erosion in the long run. However, information about the intensity of these effects on organic systems...
Termite effects on soils and plants are generally consistent along a gradient in livestock grazing
Livestock grazing is a major driver of ecosystem functions in drylands and would be expected to influence soil biota such as termites. We examined changes in soil chemistry and plant community composition on mounds constructed ...
Evaluation of Soil Texture and Organic Matter on Atrazine
% organic amanure application
respectively. It seems that atrazine in clay soils is more persistence than in sandy soils
and soil organic matters have an important role in atrazine bioremediation....
Effects of heavy metals and organic matter on nematode population in soil
risks in the soil. Also, organic compounds such as manure have an
important role in nematode population traits. The objective of this study was to investigate the impact of different levels of heavy metals (Cd, Ni, and Pb) and organic matter...
