“…Among the international publications on this subject, those of Scott et al (1992), Hodge and Lewis (1994), Conyers et al (1996), Haby and Leonard (2002), and Mello et al (2003) are worth mention. It is well known that the particle size of amending material affects productivity (Haby and Leonard, 2002) by affecting the rate at which the material goes into the soil solution, so the finer the particle size, the greater and faster the soil pH change. Despite the energy and expense required to grind limestone, finely ground lime is usually used, which is most effective on the short-term but has a low residual effect (Fernández Marcos and Paz González, 1994).…”

Liming is a common practice in Galician (NW Spain) soils devoted to pasture production. Although many studies have established the right liming rates, there is a lack of information concerning the ideal particle size for optimal agronomic results. This study aims to evaluate the effects of particle size (2Y4, 0.5Y2, 0.25Y0.5, G0.25 mm) of magnesium limestone as well as the application schedule (in a single application or split in 3 yearly applications) on the proprieties of an acid soil in Galicia and on the yield and quality of pasture growing on the soil during the 2 years after liming.The soil proprieties were monitored seasonally, and the pasture yield and nutritional contents were determined in summer and autumn. The soil analysis showed that the plots treated with a single application of the finest limestone exhibited the highest pH (pH water 5.05Y5.53), and the lowest exchangeable Al (G10% Al saturation throughout the period of study), the highest concentrations of exchangeable Ca (8.40Y10.18 cmol (+) kg j1 ) and Mg (1.39Y1.71 cmol (+) kg j1 ) and the highest effective cation exchange capacity (11.2Y13.7 cmol (+) kg j1 ). In contrast, plots treated with the coarsest limestone had values similar to control plots.The highest production of total dry matter and, especially, the highest yield of sown species were found in the plots receiving the finest limestone (0.75Y1.10 t ha j1 dry matter in summer harvest versus 0.30Y0.75 t ha j1 in control plots). Available P, exchangeable cations (K and Ca), and pH explain a high percentage of the variance of these parameters. The Mg concentrations and the total contents of Ca and Mg in plant tissues were significantly higher in the plots treated with the finest limestone.

“…CaCO 3 had the finest particle size, followed by NLS and Oldcastle, and increasing particle size is known to decrease lime reactivity (Argo and Biernbaum 1996;Barber 1984;Haby and Leonard, 2002;Love and Whittaker 1954). The NLS and Oldcastle had similar percentages of Ca and Mg, and CaCO 3 tends to be more chemically reactive than dolomite (Argo and Biernbaum 1996).…”

“…The quantity of lime required (incorporation rate), as well as the time needed to reach a stable pH, depends not only on the materials used to produce the substrate but also on the lime's chemical composition (Argo and Fisher 2002), particle size (Argo and Biernbaum 1996;Chapin 1980;Gibaly and Axley 1955;Sheldrake 1980;Williams, Peterson, and Utzinger 1988), surface area (Barber 1984;Haby and Leonard 2002;Love and Whittaker 1954;Parfitt and Ellis 1966), crystal structure (Rippy 2005), and chemical contaminates (B. Ellis, personal communications).…”

The current method for comparing the reactivity of different limestones used to correct pH in horticultural substrates is based on batch trials, where the limestones are incorporated into the substrate and the pH is measured over time (typically up to 28 days). The objective was to test a laboratory approach to provide a rapid analytical test on reactivity of various limestone sources. To a lime sample, 4M hydrochloric acid (HCl) was added, and the volume of carbon dioxide (CO 2 ) released into a burette was measured over time. Reagent-grade calcium carbonate (CaCO 3 ) and two commercially available pulverized dolomitic limestones were tested. In addition, six particlesize fractions derived from each of the limestone samples were also evaluated for reaction rate and the corresponding pH responses. In less than 1 min after acid addition, 100% of CaCO 3 reacted, whereas it took 3.9 and 11.5 min, respectively, for 50% of the limestone samples to react, and 14 and 52 min, respectively, for 90% neutralization. Reaction rate increased as the particle size decreased; however, a similar reaction rate was observed for the particle sizes larger than 150 mm 719 establish a lime reactivity index, for example based on the time required for 50% or 90% reaction, and thereby provide a rapid screening of different limestone sources.

“…Limestone was subsequently surface applied to pastures on nine different occasions from 1968 to 2002. The need for limestone was based on maintaining a pH > 6.0 in the 0‐ to 15‐cm soil depth for cool‐season annual forage production and improved nutrient‐use efficiency (Cripps et al, 1988; Haby and Leonard, 2002). The 37‐yr average annual precipitation for the experimental area was 1160 mm, with approximately 65% occurring during the February to September grazing period (Texas A&M AgriLife Research Center at Overton, 2004).…”

Impacts of Thirty‐Seven Years of Stocking on Soil Phosphorus Distribution in Bermudagrass Pastures

Pasture management aff ects soil properties, but information concerning the eff ects of long-term stocking and fertility regimens on soil P in pastures is limited. Th is study investigated changes in extractable soil P concentrations from Coastal and common bermudagrass [Cynodon dactylon (L) Pers.] pastures stocked for 37 yr at diff erent intensities on an Ultisol. From 1969 through 2004, pastures were continuously stocked during February to September to achieve high, medium, and low herbage mass. Annual fall-applied P averaged 44 kg ha -1 from 1969 to1984 and 51 kg ha -1 from 1998 to 2004. Extractable soil P concentrations in the 0-to 15-cm depth increased (P ≤ 0.0001) from 5 mg kg -1 (very low) in 1975 to 43 mg kg -1 in 2004 (high), and deeper depths showed 14 to 36% increased P levels. Elimination of P fertilizer for 13 yr, 1985 to 1997, decreased (P ≤ 0.0001) extractable soil P in the 0-to 15-cm depth by 30 and 47% in common and Coastal bermudagrass pastures, respectively. An interaction between year and stocking rate was evident as extractable P levels increased aft er 20 yr at high stocking rates. Aft er 37 yr, extractable P levels at the 0-to 120-cm soil depth followed the order high > medium ≥ low stocking rate. Despite the eff ect of stocking rate on soil P, 37 yr of continuous stocking showed no evidence of excessive P accumulation at levels that may pose an environmental threat. Phosphorus recycled through the soil-forage-animal system sustained adequate forage and animal productivity.
