| Abstract/Contents: | "Slow reactivity of coarse-grade ag-lime surface applied on soils established to perennial grasses led us to study the effectiveness of finer-ground limestone. Legume production and soil pH were used to evaluate treatments in a glasshouse experiment that included soil-incorporated and surface-applied limestone at increasing rates and effective calcium carbonate equivalence (ECCE) percentages that can be converted to kilograms of effective liming material (ELM) Mg-1. Excessive rates of limestone and the highest ECCE percentage materials decreased clover yield when applied and left on the soil surface. Comparison of ECCE 62% limestone with ECCE 100% limestone verified the initially greater efficiency of the finer lime for forage production. Four to seven years after application, annual ryegrass yields were similar for the ECCE 62% and 100% limestone materials. Seven years after the final limestone treatment, ECCE 100% limestone maintained soil pH 0.3 unit higher than pH due to the same rate of ECCE 62%. At this same time, pH of soil treated with 6.72 kg of ECCE 100% limestone was only 0.2 lower than pH in soil treated with double the rate of ECCE 62% limestone. Calculation of ELM, a term introduced to describe the weight of limestone Mg-1 that effectively neutralizes soil acidity, will enable consumers to realize the number of kilograms of effective lime in each ton, and to calculate the mass of limestone Mg-1 that will be relatively ineffective for neutralizing soil acidity. Ten times ECCE% equals ELM in knMgt-1 as calculated in equation (1). Limestone with an ECCE of 62% has 620 kg of ELM Mg-1 and 380 kg of ineffective limestone Mg-1. Pounds of ELM per short ton of limestone also can be calculated using 2,000 lb per ton." |
