Zinc (Zn) nutrition is of key relevance in India, as a large fraction of the population suffers from Zn malnutrition and many soils contain little plant available Zn. In this study we compared organic and conventional wheat cropping systems with respect to DTPA (diethylene triamine pentaacetic acid)-extractable Zn as a proxy for plant available Zn, yield, and grain Zn concentration. We analyzed...

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...

Purpose. Attapulgite was modified by sodium dihydrogen phosphate, oxalic acid-activated phosphate rock powder, potassium calcium superphosphate, ammonium and fused calcium-magnesium used in the remediation of Cd, Zn, Ni. Materials Methods. six kinds (ratio: 1 : 2), improvement effect passivation material on soil polluted cadmium, zinc, nickel determined. CaCl2-extractable toxicity characteristi...

The Lechang lead/zinc (Pb/Zn) mine and Dabao Shan copper (Cu) mine are located at the north of Guangdong Province in southern China. The residual tailings were permanently stored in tailings ponds which required revegetation to reduce their impact on the environment. A greenhouse study was conducted to evaluate the feasibility of using Vetiveria zizanioides (vetiver) and Phragmities australis (...

agaricus bisporus and agaricus bitorquis are among most favorite mushrooms of the world. mineral contents, proximate composition and fatty acid profile of these mushrooms were determined for evaluation of their dietary value. na, k and li contents were high, while cr, cu, pb, co, zn, mn and ni concentrations were low in both agaricus bisporus and agaricus bitorquis. proximate analysis showed th...

environmental pollution with heavy metals is a global disaster that is related tohuman activities. this study was conducted to determine the extent of heavy metalsaccumulation by plant species in lia industrial city (qazvin, iran) and to investigate theremediative capacity of native plant species grown in the contaminated soils. soil andindustrial wastewater sampling was done radially along tra...

The effect of increasing soil Zn concentrations on growth and Zn tissue concentrations of a metalaccumulating aspen clone was examined in a dose–response study. Plants were grown in a soil with a low native Zn content which was spiked with Zn salt solutions and subsequently aged. Plant growth was not affected by NH4NO3-extractable soil Zn concentrations up to 60 mg Zn g 1 soil, but it was compl...
