A range of soil amendments including diammonium phosphate fertilizer (DAP), municipal biosolids (BS), biosolids compost, and Al- and Fe-based water treatment residuals were tested on Pb-, Zn-, and Cd-contaminated yard soils and tailings at the Tar Creek NPL site in Oklahoma to determine if amendments could restore a vegetative cover and reduce metal availability in situ. For the yard soils, all...

this research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. applied nutrients were zinc sulphate (zn) of 0.0 and 1.5gl-1 and urea (n) at 0.0 and 5 gl-1 and fe (1) control (low fe)...

A field study was conducted to assess the agronomical performance of eggplant (Solanum melongena cv. Pusa Purple Long Hybrid-F1) grown in sewage sludge amended soil in rainy and summer seasons during two consecutive years 2012 and 2013. The results showed that sewage sludge significantly (P < 0.05/P < 0.01) increased the Organic Carbon (OC), sodium (Na + ), potassium (K + ), calcium (Ca 2+ ), m...

Abstract The immobilization effect of soil amendments on leaching and bioavailability Pb, Zn Cd in highly contaminated soils under industrial impact was studied by collecting the surroundings Zn-Pb Smelter “Miasteczko Śląskie” southern Poland as an example. Various amounts four additives (phosphate fertilizer, limestone powder, bentonite rock bog iron ore) were tested laboratory experiments to ...

Beans require adequate amounts of all essential plant nutrients for optimum growth but only a few nutrients are documented to be needed for southern Idaho soils. These nutrients include phosphorus (P), nitrogen (N), zinc (Zn), potassium (K), sulfur (S), and to a much less extent B, Cu, Mn and Fe. University of Idaho Agricultural Experiment Station research as well as research from throughout th...

to compare potential of two organic materials including sewage sludge (ss) and municipal solid wastecompost (msw) on micronutrients entry to soil, a research was conducted as split-plot arrangement basedon randomized complete block design with three replications in research field of sari agriculturaluniversity. main-plot (fertilizer treatments) included 20 and 40 ton/ha ss, 20 and 40 ton/ha ss ...
