Cadmium, copper, nickel, and zinc availability in a biosolids-amended piedmont soil years after application.
Concerns over the possible increase in phytoavailability of biosolids-applied trace metals to plants have been raised based on the assumption that decomposition of applied organic matter would increase phytoavailability. The objectives of this study were to assess the effect of time on chemical extractability and concentration of Cd, Cu, Ni, and Zn in plants on plots established by a single app...
متن کاملInfluence of Herbicide Triasulfuron on Soil Microbial Community in an Unamended Soil and a Soil Amended with Organic Residues
The effect of organic amendments and pesticides on a soil microbial community has garnered considerable interest due to the involvement of microorganisms in numerous soil conservation and maintenance reactions. The aim of this work was to assess the influence on a soil microbial community of the simultaneous application of the herbicide triasulfuron at three doses (2, 10, and 50 mg kg-1), with ...
متن کاملThe Relationship Between the Chemical Forms of Copper in the Soil Solid Phase Affected by Crop Residues With Phytoavailability of Copper in Soil
Returning crop residues into the soil as a source of organic matter are an important source of copper and can play an important role in the soil fertility. In addition to the role of the organic matter in increasing the concentration of micronutrients in soil solution, attention should be also paid to the role of the kind and the quantity of the root’s exudates released in response to the incor...

متن کاملcarbon and nitrogen mineralization in a calcareous soil amended with plant residues and sulfur
carbon (c) and organic nitrogen (n) mineralization processes play key roles in supplying nutrient elements essential for plant growth. on the other hand, since the low organic matter content of agricultural soils of arid and semi-arid areas, microbial activities are often limited by carbon in these types of soils. enhancement of microbial activities and populations could be achieved by returnin...
