Soil balancing (SB), or base cation saturation ratio (BCSR), is a soil management approach that strives to maintain specific calcium (Ca) and magnesium (Mg) levels improve health, decrease pest problems, have better crops, increase crop yield. To achieve ideal of Ca Mg, BCSR practitioners apply gypsum (calcium sulfate) high-calcium lime (Hi-Cal lime) amendments, with the former increasing later...

During the latter part of 1975 an investigation was conducted in the Natal Midlands to locate sites, representative of the main bioclimatic subregions, that would be suitable for sugar beet experiments. Soil acidity was identified as an important limiting factor in the majority of soils examined. A glasshouse study with sugar beet revealed a marked response to lime where soil pH values were les...

For crops to have good productivity, it is necessary adopt agricultural practices that ensure an adequate supply of water and nutrients, neutralize toxic elements in the soil, especially exchangeable aluminum, both arable layer subsurface. One these usually employed small medium large rural properties correction soil acidity, which aims, addition neutralizing provide calcium magnesium for plant...

96 AI MAGAZINE An adequate use of land resources is an essential guarantee of sustainable development, and many authors have suggested different approaches (Chi-Mei et al. 2002; Stewart, Janssen, and van Herwijnen 2004; Matthews et al. 2000; Tsuruta, Hoshi, and Sugai 2001; Bocco, Sayago, and Tartara 2002). The optimal use of soils is the basis of all forms of sustainable land use, that is, agri...
