Interest in the determination and screening of pesticide residues in soil is caused by widespread use of chemical pesticides in agriculture, which increase soil contamination. Two extraction techniques, matrix solid phase dispersion (MSPD) and liquid-liquid extraction (LLE) of residual pesticides (acaricides, insecticides, herbicides, and fungicides) from soil were compared. Advantages and disa...

Soil compaction by farm machinery may persist for decades, hampering soil productivity and functioning. Assessing costs guiding recovery strategies are hindered paucity of data on structure rates. A long-term Structure Observatory was established a loamy in Switzerland to monitor after prescribed compaction, better assess the roles natural processes (vegetation, macrofauna, shrink-swell cycles)...

Studies about organic fertilization demonstrate the effectiveness of nutrients from residues to get improvement soil attributes. Therefore, this study aimed evaluate effect adding cattle manure on chemical The experiment was carried out at an experimental area Federal University Tocantins, Gurupi campus. design randomized blocks with three replications. treatments corresponded eight rates (2,5;...

Conifer control in sagebrush steppe of the western United States causes various levels of site disturbance influencing vegetation recovery and resource availability. The data set presented in this article include growing season availability of soil micronutrients and levels of total soil carbon, organic matter, and N spanning a six year period following western juniper (Juniperus occidentalis s...

Overland flow connectivity and runoff and sediment trap effectiveness are currently the cutting edge topics in soil erosion research. The effect of agricultural terraces, irrigation channels and trails on runoff and soil erosion modelling at catchment scale is still a remaining research question. In this study we run the index of connectivity of Borselli et al. (2008) and a modified version of ...

Vela, Gerard R. (School of Aerospace Medicine, Brooks Air Force Base, Tex.), and Orville Wyss. Radiation resistance of soil Azotobacter. J. Bacteriol. 89:1280-1285. 1965.-Quantitative recovery of Azotobacter from soils subjected to gamma-radiation from a cobalt-60 source showed the soil populations to be much more highly resistant than isolates from such cultures grown on laboratory media. Even...

BACKGROUND The Loess Plateau, an ecologically vulnerable region, has long been suffering from serious soil erosion. Revegetation has been implemented to control soil erosion and improve ecosystems in the Loess Plateau region through a series of ecological recovery programs. However, the increasing atmospheric CO₂ as a result of human intervention is affecting the climate by global warming, resu...

Tetracycline residues in the soil were investigated in this study due to their wide use in veterinary medicine and fertilization of agricultural fields with manure containing antibiotics. Soil samples were characterized by using various physicochemical parameters. Solid phase extraction and high performance liquid chromatography were used to detect oxytetracycline and chlortetracycline residues...

the use of metal-accumulating plants to clean the contaminated soil with toxic metals is the most rapidly developing component of phytoremediation as an environmentally friendly technology. overcoming harsh soil conditions and accelerating the recovery of degraded soils remain a worldwide restoration challenge. this study evaluated the effect of different concentrations of pb, zn, cu and fe on ...

-We summarize 8 years of soil physical property responses to herbicide manipulation of the understory in two young longleaf pine stands growing on either Ruston fine sandy loam or Beauregard silt loam soils. We also describe relationships between pine sapling vigor and the soil physical environment across a 3-year period on the Ruston soil and a 2-year period on the Beauregard soil. It is hypot...
