Glyphosate [N-phosphonomethyl]glycine is a systematic, non-selective, organophosphorus herbicide used worldwide in agriculture and industrial zones. Following its application, residues of glyphosate can threaten soil or aquatic organisms in adjacent water. In this study, we followed the degradation, stabilization, remobilization and leaching of C-glyphosate in three agricultural soils in labora...

Soil degradation and salinization are two of the utmost threat affecting agricultural areas, derived from the increasing use of low quality water and inappropriate cultural practices. The problem of low productivity of saline soils may be ascribed not only to their salt toxicity or damage caused by excess amounts of soluble salts but also arising from the lack of organic matter and available mi...

One of the fundamental lessons learned through the past half century of agricultural research is that there are no “one size fits all” best management practices. The interaction of different soils with different cultures in different climates results in the need for unique approaches to sustainable agricultural systems in each situation. The transition to systems that are both sustainable and s...

Agricultural soils contain both heavy metals and pesticides originating from various agricultural practices. It is quite important to study the relationships between these two classes of compounds. To accomplish this, 52 soil samples were collected from cotton fields and analyzed for their metal contents (Ni, Cu, Co, Pb, Cr, and Cd) and levels of most commonly used pesticides (imidacloprid, ace...

Organophosphate pesticides are of great interest for research because they are currently the most commonly used pesticides. In this study, a bacterial strain capable of completely degrading methyl parathion (MP) was isolated from agricultural soils in central Mexico. This strain was designated strain S5-2 and was identified as Burkholderia cenocepacia. To increase degradation yields, cells were...

Three soils with different tillage activities were collected and compared for their organic matter sources and degradation. Two soils (TD and TP) with human activities showed more diverse of chemicals in both free lipids and CuO oxidation products than the one (NS) without human activities. Branched alkanoic acids only accounted for less than 5% of lipids, indicating limited microbial inputs in...

Pesticide residues in Indian agricultural soils due to extensive and sometimes indiscriminate use still pose a serious problem for the production and export of agricultural goods. Residues of pestcides including HCH (hexachlorocyclohexane) have even been detected in popular soft drinks such as CocaCola and Pepsi. In addition, at pesticide production sites, soils of the surrounding area are ofte...

Assessment of the content and sources of heavy metals in soils is required to identify agricultural areas affected by contamination on a regional level, according to the European Thematic Strategy for Soil Protection. The total content of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn of 29 agricultural soils used to grow vegetable crops such as artichoke, broccoli, and potato, in the Segura River Valle...

Introduction One option for sequestering carbon in the terrestrial biosphere is to increase the carbon (C) stocks in agricultural soils. There is now an extensive literature on the amount of C that has been lost from soils as a consequence of humans disturbing natural ecosystems, and of the amount of C that might be returned to soils with improved management practices. Improvements in managemen...

during this research, bacteria resistant to metals were evaluated in the soil of isfahan province.according to the sampling locations the soils are classified as agricultural soils, non-agricultural soils andsediments of the zayanderood riverbank. the bacteria resistant to lead (2 mm), copper (5 mm), cadmium(0.5 mm) and arsenic (5 mm) were identified, and then during later stages, the minimum i...
