Mehlich-3 (M-3) is used as a universal nutrient extractant due to its ability simultaneously extract multiple elements. This study aimed assess M-3 for the simultaneous determination of plant-available zinc (Zn), copper (Cu), iron (Fe), manganese (Mn), boron (B), and sulfate (SO4-S) in soil amended with switchgrass- (SGB) poultry litter-derived biochars (PLB), which were vary pH values (5.7–7.6...

A commonly-used method in ore exploration is hydrogen peroxide ammonium citrate (HA) extraction, which has not typically been used waste rock characterization. In this study, the sulfide specificity and leaching of other minerals HA extraction was evaluated its performance compared with aqua regia (AR) for preliminary assessment harmful element mobility. Samples collected from several different...

Four soil profiles located near a copper smelter in Poland were investigated for the distribution and chemical fractions of Cu, Pb, and Zn and their mobility in relation to soil properties. Contamination with heavy metals was primarily restricted to surface horizons and the extent of contamination was 7- to 115-fold for Cu, 30-fold for Pb, and 6-fold for Zn as compared with subsurface horizons....

The use of diffusive gradients in thin films (DGT) for predicting metal bioavailability was investigated by exposing the bivalve Tellina deltoidalis to an identical series of metal-contaminated sediments deployed simultaneously in the field and laboratory. To understand the differences in metal exposure occurring between laboratory- and field-based bioassays, we investigated changes in metal fl...

We consider the problem of quantifying the information shared by a pair of random variables X1,X2 about another variable S. We propose a new measure of shared information, called extractable shared information that is left monotonic; that is, the information shared about S is bounded from below by the information shared about f(S) for any function f . We show that our measure leads to a new non...

ABSTRACT- To evaluate effects of different soil moisture conditions namely, phosphorus (P) and zinc (Zn) application, on extractable Zn and Fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. The first experiment was performed with the following factors; incubation time at four leve...
