Zinc (Zn) availability and mobility in soils is controlled by its interaction with the soil matrix and amendments. Contradicting evidence has been reported for factors influencing Zn behavior in soils. The aim of this study was to investigate the Zn sorption in selected acid, calcareous and gypsiferous soils with different background electrolytes (Na+, K+ and H2PO4, NO3 and Cl backgrounds). Iso...

Lonicera confusa was a medical plant which could adapt to the Ca-rich environment in the karst area of China. The photosynthesis, relative chlorophyll content,differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) of L. confusa that cultivated in calcareous and sandstone soils were investigated. The results showed that the relative chlorophyll content and net photosy...

Management strategies that minimize P transfer from agricultural land to water bodies are based on relationships between P concentrations in soil and runoff. This study evaluated such relationships for surface runoff generated by simulated sprinkler irrigation onto calcareous arable soils of the semiarid western United States. Irrigation was applied at 70 mm h(-1) to plots on four soils contain...

The objective of this study was to assess the functional response of microbial communities to sulfur amendment in calcareous organic soils of the Everglades Agricultural Area in south Florida. Soils under sugarcane cultivation were amended with elemental S at four rates up to 448 kg S ha to decrease pH and enhance nutrient availability. Soil samples were collected 2, 6, 9, and 13 months after S...

phosphorus (p) sorption in soils is a key process governing its availability to crops. there has been scanty information available on the p sorption characteristics of calcare-ous soils of western azarbaijan province, iran. in this study, p sorption characteristics and their relationship to soil properties were determined in 36 soil samples belonging to 15 agricultural soil series located in th...

in this research, several chemical extractants and modified olsen methods were studied in 25 surface-calcareous soils (0-30 cm) for determining available phosphorus (p) for corn (zea mays l.) plant. in this experiment, the highest correlation was obtained between extracted p by olsen and colwell methods (nahco3-extractable p) and dry weight of corn shoot (r =0.67 and 0.75, p

According to previous studies, acidic soils may receive larger quantities of 2,4dichlorophenol (2,4-DCP) and of 2,4,5-trichlorophenol (2,4,5-TCP) than the concentrations indicated in the prevailing legislation for defining a soil as contaminated, without any important changes in their biochemical properties. In this study, we investigated whether neutral or slightly alkaline soils behave in the...

The fate of organic herbicides applied to agricultural fields may be affected by other soil amendments, such as copper applied as a fungicide. The effect of copper on the leaching of diuron and glyphosate through a granitic and a calcareous soil was studied in the laboratory using sieved-soil columns. Each soil was enriched with copper sulfate to obtain soil copper concentrations of 125, 250, 5...

In view of the growing awareness about eco-friendly organic farming, vermicompost (VC) could be a very good option for increasing crops yield. The organic carbon in VC releases nutrients slowly and steadily into the system and enables the plant to absorb these nutrients. To assess the effect of VC on soil fertility, growth and yield of stevia in acid and non-calcareous soils, an experiment was ...
