Soil water, soil chemical and crop variations in a clay soil
Spatial properties of field soils vary in a complex manner. Especially in arid and semiarid areas, this variability affects plant quality and crop production. An experimental field plot was extensively sampled regarding soil water (378 gravimetrical samples), soil chemical content (314 samples), and crop yield and chemical content (26 samples) at the Cherfech agricultural field research station...
متن کاملHeavy metal interactions with phosphatic clay: sorption and desorption behavior.
Heavy metals produced and released during agricultural and industrial activities may pose a serious threat to the environment. This study investigated the effectiveness of phosphatic clay, a by-product of the phosphate mining industry, for immobilizing heavy metals (Pb(+2), Cd(+2), and Zn(+2)) from aqueous solutions. A batch equilibrium technique was adopted to evaluate metal sorption in the pr...
متن کاملSoil Organic Carbon Sequestration in Reclaimed Minesoils
Land disturbance during mining results in loss of soil organic carbon (SOC). Reclamation of minelands can lead to recuperation and sequestration of SOC. The SOC thus accumulated, not only replenishes SOC losses but may also offset additional carbon di-oxide (CO2) emission. The assessment of the above was done on a chronosequence of reclaimed minesoils comprising pasture with topsoil application...
متن کاملTillage impacts on aggregate stability and crop productivity in a clay-loam soil in central Iran
To take advantage of conservation tillage systems (including direct drilling and non-inversion) in central Iran, it is important to study the effects of different cultivation practices on soil structural stability as a physical indicator. A four-year study was conducted to investigate the effects of seven tillage systems on aggregate properties of a clay-loam soil (Calcic Cambisol) with continu...
متن کاملCharacterization of aqueous lead removal by phosphatic clay: equilibrium and kinetic studies.
Immobilization of heavy metals from contaminated environments is an emerging field of interest from both resource conservation and environmental remediation points of view. This study investigated the feasibility of using phosphatic clay, a waste by-product of the phosphate mining industry, as an effective sorbent for Pb from aqueous effluents. The major parameters controlling aqueous Pb remova...
