Jun 01, 2009The finer the particle size of the limestone powder, the faster acting the lime will be. In general, the soils in Western North Carolina are naturally high in magnesium, so in most cases dolomitic limestone would not be the preferred lime for this area.
получить ценуDec 01, 1991Boxwood liners, Buxus sempervirens ''Suffruticosa'', were containergrown for two years in a pine bark/peat moss medium amended with various particle sizes of dolomitic limestone. Adjustment of pH was more effectively accomplished with the finer particles. All treatments resulted in greater plant growth than the untreated control.

получить ценуThe specific surface area of the cement (area per unit mass) can be calculated from the particle size distribution parameters. The greater the slope, the narrower is the distribution. For equal specific surface area, cements with a narrower distribution have a smaller position parameter x'' and thus a higher proportion of the fine particles.
получить ценуThe LA960 Laser Particle Size Analyzer quickly and easily measures dry powders such as trona or wet materials such as a lime slurry. Any sample with particle size between 10 nanometers and 5 millimeters may be measured in less than 60 seconds with the LA960. Dry powders are measured using the PowderJet accessory.

получить ценуThe recommended rates and the effect on soil pH of any agriculture lime product is related to the neutralizing value of the lime, which is a combination of the purity (calcium carbonate equivalent) and the fineness of grind (particle size). As these two properties of lime change, so does the recommended rate of lime and its effect on soil pH.
