the low bioavailability of zinc (zn) is in calcareous and saline soil, therefore the study of chemical forms and bioavailability of zn in these soils is necessary to estimate the potential availability. the objective of this study was to evaluate the effect of plant growth promoting rhizobacteria and mycorrhizae fungi inoculation on the chemical forms of zn in a calcareous soil at different sal...

Phosphorus (P) is the restraining aspect in forest ecosystem, particularly temperate regions, and makes ecosystem more liable to nitrogen (N)-derived acidification. However, it remains poorly understood how N P fertilization together affects soil-P availability other soil properties. To address this question, a factorial experiment was conducted with additions under two ecosystems, i.e., Korean...

The effects of iron oxides and organic matter on the partitioning and chemical lability of U and Ni were examined for contaminated riparian sediments from the U.S. Department of Energy's Savannah River Site. In sequential extractions of four sediments that ranged from 12.7 to 82.2 g kg(-1) in organic carbon, U was found almost exclusively in moderately labile fractions (93% in acid-soluble + or...

Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...
