Since 1985 two series of field trials have been conducted or established to assess the value of lime and phosphogypsum for the amelioration of aluminium toxicity. The first series considered their use on weak, coastal sandy soils and the secondconcerned their use on midlands' acid soils with high clay and organic matter contents and under the minimum tillage system. On weak sandy soils the over...
O of the greatest difficulties experienced in developing a wellbalanced system of agriculture in the southeastern states is associated with a soil peculiarity that has heretofore made it impractical to use lime except at limited rates of application. For some time liming has been known to promote a deficiency of available manganese on extensive areas, but the soils involved are generally relati...

Phytostabilization of mine waste: growth and physiological responses of Vigna unguiculata (L.) Walp.
Greenhouse experiments were carried out for phytoremediation of the Pb/Zn abandoned tailings (pH 3.2 and high metal content) of Rampura-Agucha Mines, Rajasthan. Vigna unguiculata (L.) Walp. (cowpea) was chosen as a test crop. On unamended tailings, the seeds of the test plant showed no germination. The tailing was amended with lime (3% on weight basis), 3% lime + NPK (diammonium phosphate at 60...
of a Master's Thesis in Human Biology at the University of Indianapolis filed June 2000 Dr. Stephen P. Nawrocki, Chair Dr. Christopher W. Schmidt, Reader Of the many factors that affect buried remains, one that is particularly pertinent to forensic studies is the inclusion of lime in a burial. It would seem that assailants believe that lime accelerates the decomposition of soft tissues in burie...
The purpose of this paper is to advance the knowledge on peat soil stabilization by critically examining and documenting the current state of practice. Deep mixing method is emphasized on column type techniques using lime/cement. This paper is essentially a comprehensive review of available academic literature on deep soil stabilization utilizing this approach. Deep mixing with lime or lime-cem...
The kinetics of calcination of a high calcium type of limestone was studied. Ukpilla limestone found in the central region of Nigeria was studied. The limestone composition shows that the limestone has 51.29% calcium oxide and 41.53% loss on ignition and magnesium oxide content of 2.23%. The following parameters were determined; diffusion coefficient of lime layer, and mass transfer coefficient...
Wazirpur industrial area of Delhi generates a huge quantity of sludge per day, which is highly acidic in nature (pH 2.7 to 4.4) and contains macronutrients, micronutrients as well as toxic metals. A pot-culture experiment was conducted by taking the two soils (JNU and Chhattarpur) amended with sludge (0%, 10%, 20%, 30%), pretreated with lime (0%, 0.5% and 1%). Two wheat seedlings were planted p...
1. Abstract This paper presents a geostatistical approach to model uncertainty about the spatial distribution of soil properties and to propagate it through a crop model, allowing for incorporation of uncertainty in the choice of management scenarios (no lime, single-rate liming and site-specific lime applications to acidic field soil). The methodology involved modeling the uncertainty about wh...
A mortar is a material resulting of the intimate mixture of sand grains, a binder (lime, cement, etc.) and water. The properties and characteristic of the mortars mainly depend on the nature of the binder component. That is the reason for which, its evolution with time has been very related to the development of artificial cementitious materials. So, with the consolidation of the Roman civiliza...
