Mesh or mesh size refers to to the number of open slots per linear inch in a grinding seive.

98-G is made from limestone that is 95% pure calcium carbonate, crushed to 100 mesh giving it an ECCE of 91%. The extremely fine, high quality lime is then granulated to ensure 100% reaches the soil to adjust pH!

The majority of AgLime is only 50% effective, due to poor quality and course grinding. The other 50% of the ton is composed of fine particles that are susceptible to drifting which can cut the effectiveness another 25%, leaving the grower with only 25% of what he paid for.

Another way of looking at it is; 1 ton of 100 mesh lime will equally cover 200,000 square feet, or 4.6 acres. 1 ton of 30 mesh lime will equally cover 51,000 square feet or 1.2 acres. Due to the finer grind of 98-G it will cover 1 acre as equally with only one-fifth (200,000/43,560) as much lime as a coarse ground lime.

Fine lime particles react more quickly in the soil. Notice that the 20-30 mesh sizes do not raise the pH very much and it takes 18 months to reach their maximum pH increase. AgLime typically only passes 30-40% of 1 ton through the 60 mesh sieve, while passing almost 100% through the 8 mesh.

Pelletizing is the best way to put fine particles on the ground.

Remember that finer particle sizes cover more square feet. Material passing the 100 mesh will cover 56 percent more area then the material passing the 60 mesh. So when we say 300 - 400 pounds per acre, you know you are getting 85 to 92 percent coverage on every acre you spread, with no fine particles drifting away, no extra water, and no coarse particles doing nothing for your soil.
