WebSoils containing sorbed SO42- had lower Ca2+ sorption efficiency, higher lime requirements, lower pH's and higher specific conductivities than those containing sorbed OH-. These effects were the result of replacement of sorbed SO42- by OH- according to the reaction: Soil-SO4 + Ca(OH)2 Soil-(OH)2 + CaSO4. 展开 WebMar 1, 2013 · The simplest approach to resolve low soil pH is to raise it to a more suitable level. Liming is a common means of raising soil pH; applying CaCO 3 to bind excess H + while at the same time releasing Ca 2+ which can be used as a nutrient. 72 However, poor mixing of CaCO 3 with soil 73 and over-liming can reduce crop yield, 74 meaning liming is ...

WebSoil pH stratification after 25 years of no-till and surface nitrogen fertilizer application, ... Research has shown that as long as the surface is in an appropriate range and the remainder of the acid soil is above pH 5, crops will do fine. Liming benefits crop production in large part by reducing toxic aluminum, supplying calcium and ...

The primary reason for liming acid soil is to bring soils to an optimum pH which makes nutrients more available to plants improving yield or quality of the crop being grown. A number of soil parameters change simultaneously as soil acidity is reduced by liming. population of irving township mi
