The addition of lime as Ca(OH)2 to sewage sludge to destroy pathogens (Escherichia coli), was evaluated also in relation to heavy metal bioavailability. The obtained results show that the use of calcium hydroxide at the dose of 3% effectively destroyed pathogens ensuring the stability at high pH values over long period and the duration of the sewage sludge stabilization. In general, lime additi...

Acidic (pH 4.1) and high Cd, Pb, and Zn mine tailings (mean +/- SD: 17 +/- 0.4, 3800 +/- 100, and 3500 +/- 100 mg kg(-1), respectively) from an alluvial tailings deposit in Leadville, Colorado were amended with municipal biosolids (BS) (224 Mg ha(-1)) and different types of lime (calcium carbonate equivalent of 224 Mg ha(-1) CaCO3) in a greenhouse column study to test the ability of the amendme...

Gypsum is hydrated calcium sulfate (CaSO 4 • 2H 2 O), and is often marketed as a soil " conditioner " for improving soil " tilth. " Compared to most other calcium-rich soil amendments, such as limestone, gypsum is relatively soluble in water, dissolving up to 2 g per liter. The solu-bility of gypsum, when either incorporated or surface applied, permits a quick release of calcium (Ca 2+) and sul...

Casamance is a region in southern Senegal that traditionally produces rainfed rice, but Senegal produces only 1/3 of its rice consumption. Lowland areas, where rice is primarily produced, have acid sulfate soils with low pH and potential aluminum and iron toxicity. The goal of this work was to determine if soil amendments can alleviate soil acidity, counteract the negative biogeochemical effect...

The experiment was laid down on October 3rd, 1932, at Hazara Estate, Kearsney, the property of The .pH gives an idea of the "force" .of .the free acids in the soil, but one can easily understand that two different soils, with different physica-l properties but the same degree of acidity in terms of pH, will not react in the same manner to identical lime treatment; for example, sandy soils poor ...

Many active and formerly used Federal facilities contain areas where surface and subsurface unsaturated zone soils are contaminated with explosives. Currently there is no in situ treatment for stabilization, isolation, or remediation of soils impacted by military operations or manufacturing in support of military operations. The objective of the present work was to evaluate in situ lime treatme...

This study was conducted to investigate the effect of Rhizobium inoculation and the supply of Mo and lime on the uptake of macroelements in P. vulgaris. To achieve this aim, experiments were conducted at the glasshouse of the Cape Peninsula University of Technology, Cape Town (i.e. from August 2008 to January 2009) and field experiment at the Agricultural Research Council (ARC) Nietvoorbij site...
