What you get with ag lime
March 11, 2008
Written By: Craig Dick

For many years pelletized lime has been cast off as too expensive, renter’s lime, or a quick fix. Ag lime has been regarded as long lasting, what land owners use to make long term fixes. There are a number of other things that I think of when I think of ag lime;

Drift

Unfortunately the best portion of lime is most likely to drift. Even if you’re the one farmer that gets his lime spread on a calm day, the floater is traveling 10-15 mph, and throwing the lime out at 70+ pounds per square inch. There is no other way to avoid drift than to pelletize the lime (click on photos for large view).

Poor Spreading

You paid for VRT/GPS spreading, not stripped fields

 
Slow ROI

In a University of Nebraska on Farm Research project they considered a 2-ton application of ag lime had a 7 year life span. It took 4 years to get a yield response and 7 years to get an adequate pH change. If I were spending $40 per acre I would expect that money to have a better return than 6 bushels in 4 years!

Application Problems

Large patches of compaction, piles of stalks, areas that are over limed. Do they do that for free…..

 
 

At equivalent rates SuperCal 98G is the same cost or less than ag lime.
Renters us it because it works, returning their investment the year it is applied.
You wouldn’t put on 7 years worth of phosphates of potassium, put on what you need, spend you money on something else.

Reduce the headaches, increase yields, quickly, spread only the lime you need for the next couple of years.
