At 3 g·L −1, the intermediate limestone particle size fractions of 250 to 850 μm and 150 to 250 (20 to 60 or 60 to 100 US mesh) provided the greatest pH-buffering with impatiens. Particle fractions finer than 150 μm reacted quickly over time, whereas buffering by particles coarser than 850 μm was limited because of the excessively slow reaction rate during the experimental periods.

Mosher Limestone Company Limited

Granular limestone is generally more useful on a mature and well maintained soil. This is because of the much larger particle size; it takes about three years to break down completely into the soil. If your pH levels are consistent, spreading granular limestone annually will ensure your soil quality remains high.
