Right now!! If you are using pellet lime you need to get it on as soon as possible. If the soil is acidic you will need 2,000 lbs per acre. This is if you are using (powdered Agriculture Lime) Need a soil sample for sure!! If you are using pellet lime you can cut this in half. It all depends on you soil test!! After you apply you lime then you can come back before you plant and put down Rapid Lime. 2:1 ratio of powdered lime vs pellitized lime in most cases meaning it takes 2,000 pounds powder to equal 1,000 of pelletized.
The pelletized is a more concentrated version of powder that has a cementing agent that bonds it into a pellet. It is easy to put out, and works faster, but it doesn't last as long as powder, but it is at least 2-3 times more expensive comparing the 1:2 ratio, and to the unknowing consumer basing it on 1:1 it seems to be 4-6 times more expensive. For either it is best to put out on bare soil, and then till it into the ground 3-4 inches for it to work faster and have less runoff from rains.... It is best to put out at least 3-4 months prior to planting... I hope this helps....

Benj,
In this stituation your only option is pellet lime and a Rapid Lime combo for the best results on your spring plots. We've missed the boat on Ag lime (needs to be applied in the fall for spring plantings) for the desired results this spring. It usually takes 6 months for the Ag lime to start adjusting soil pH. Pellet lime will take approximately 3-4 weeks to start adjusting your soil pH, we can utilize Rapid Lime for a quick pH jump until the pellet lime takes over. You can apply Ag Lime this spring, it won't benefit your plots until mid fall. You can apply Rapid Lime again this fall on your plots to give you a pH spike until the Ag Lime begins neutralizing the acid in the soil. Depending on soil type you should only have to Ag Lime your plots every 3-5 years.
