background: to determine the efficacy of different antiseptic solutions (control group (i), antibiotic solution (ii), chlorhexidine 0.4% (iii), and povidone – iodine 10% (iv)) in sterilizing contaminated osteochondral plugs. methods: under sterile conditions, the femoral head and condyles of 20 rabbits were removed and cut into equal osteochondral pieces. a total of 200 osteochondral specimens ...

present study determines not only the total amounts of metals (cr, cu and pb) in superficial agricultural soil of sistan area in eastern iran, but also the chemical partitioning of these elements in seven statistically selected cases. the analysis was run for local soil, soil treated by non-contaminated organic, compost and chemical fertilizers as well as soil treated by metal-contaminated fer...

abstract rhizosphere is a small zone with chemical, physical, and biological properties different from those of the bulk soil. information regarding the kinetics of cu release in the rhizosphere soil is scant. throughout this research, kinetics of cu release was investigated in wheat crop rhizosphere vs. non-rhizosphere in 10 calcareous soils by use of rhizobox and in greenhouse conditions. ext...

The superficial strata of ground have been perennially exposed to the action of natural agents such as heat, cold and water. However, grazing agent was not different from them when soils were investigated from temperate rangelands of Kashmir and caused the soil compaction, soil structure degradation and loss of soil organic C and C/N ratio. Soils from three grazing intensities were investigated...

aims: in the past few decades, more attention has been paid to clean up soils polluted with heavy metals by plants. a serious problem in this way is the amount of heavy metals uptake by plants. this study was conducted to evaluate the effectiveness of 3 local plants of mazandaran province, iran, in reducing and controlling the soil’s heavy metals. instrument & methods: the removal amount of thr...

[1] We developed a process-oriented hillslope soil mass balance model that integrates chemical and physical processes within hillslope soils. The model explicitly factors that soil chemical weathering at any hillslope position is related to the flux of soil eroded from upslope as well as soil production from underlying bedrock. The model was merged with measurements of soil elemental chemistry ...

long-term application of fertilizers containing p, especially organic fertilizers, usually increases the water soluble and available p of soil and at the same time may result in p accumulation in soil. organic fertilizers may also increase movement of p in the soil profile that could result in surface and ground water pollution. an experiment was conducted on field plots that received three app...
