Understanding Ag Lime

Liming materials are typically carbonates of calcium or magnesium.

CARBONATE is what helps to neutralize acid in the soil.

Chloride, especially calcium chloride does not!

How does granular Ag lime work?

The most widely used Ag lime is primarily in the form of calcium carbonate.

Once the granular lime is applied, the acid in the soil attacks the lime and slowly dissolves it

particle allowing it to release the carbonate and calcium into the soil.

The carbonate then binds with hydrogen which in turn neutralizes the acid and then buffers the soil pH. 

 The Calcium from lime is a nutrient, It does not have a role in the neutralizing process.

How quickly the lime particles break down depends on the type of soil and the amount of acid in the soil. If the soil is only slightly acidic, very little if any calcium will be delivered to the plant.

 

This means we sometimes see little to no substantial return on investment.

Did you know?

Once acid in the soil has been neutralized,

the lime stops working  until more acid is formed

THE PROCESS STOPS

With the lack of acid needed for the particle breakdown process to happen, the lime will not deliver any more calcium.

 

Calcium is needed throughout the growing season for nutrient mobility.

 

Calcium helps to bring other nutrients into the plant as well. If not enough calcium has been released, it eventually will get depleted or locked up again.

 

Lack of  ORGANIC MATTER  is the number one reason our soil loses it's balance.
