More Crops, Lower
Costs - Agricultural
Lime May be the Key
AGRICULTURAL LIME, OR AGLIME, is
a soil conditioner most commonly produced from finely crushed limestone.
It provides a source of calcium and
magnesium for plants, increases the
pH of acidic soil, enhances water penetration, and improves the uptake of
nitrogen, phosphorus and potassium

Most U.S. states have unique
specifications for Aglime.

The following states don't list sieve sizes: Arizona, Hawaii, New Mexico, North Dakota, Rhode Island, South Dakota,
Texas, Utah and Wyoming. Colorado and Nevada have alkaline soil that requires the addition of acids to adjust soil pH.

or NPK. For farmers, this means lower
crop production costs, but for quarries with the proper chemistry for
Aglime production, it equals another
product to sell.
Reducing soil acidity reduces unfavorable conditions caused by iron,
aluminum and manganese. It also
increases the availability of critical
plant nutrients (nitrogen, phosphorus, and potassium) by providing
an environment that allows microorganisms to break down organic
matter, and it increases the effectiveness of herbicides. The Michigan
State University's Extension Bulletin
E-1566 states, "Aglime can return $5
to $10 for each dollar invested in
lime. Raising soil pH from 5.7 to 6.5
in mineral soils may improve corn
or soybean yields by 20 percent or
more, and alfalfa yield by 35 percent
or more."
When Aglime comes in contact
with the acids in the soil, calcium
(Ca) moves to the surface of soil
particles, replacing the acidity. The
acidic H+ ions react with the carbonate (CO3) to form carbon dioxide (CO2)
and water (H2O). The result is a soil
that is less acidic (has a higher pH).
Why does size matter for Aglime?
The smaller the particle size, the
higher the percentage is absorbed
in the soil within the first year of
application. Particles smaller than
50 mesh - 100 mesh are completely
absorbed within the first year of
application - 100-percent effective.
