Pelletized lime will work quite well. You can get by using it a much lower rate than regular ag lime. About 200-300#/ac compared to 1 ton/ac. The reason for this is because the grind on the lime for pelleting is much, much finer than that of ag lime resulting in about a 10 fold increase in available surface area to react with the soil particles. This also allows pelletized lime to work much faster. About 30 days. The downside is that all neutralizing effect is gone in about 6-9 months. So it has to be applied every growing season. Whereas regular ag lime takes 6 months to begin working and will continue working for 2-4 years beacuse of the much larger particle size making it much harder to disolve into the soil. I remember a year back in the 90's when it got too wet after the harvest a lot of row crop farmers could not get on their fields until April. A lot of them mixed pelletized lime in with their pre-plant fertilizer which worked quite well for that year. They still came back and spread regular ag lime in the fall. It was too costly to use on yearly basis.
Actually there is no research that supports it acts any faster then Lime meeting most state lime laws. If the calcium equivilent of quarry or pelletized lime is 90% then putting on 300 lbs. of pelletized vs. 2000 lbs. of ag lime in whatever form it is scientifically impossible to get more buffering capacity from the smaller amount of pelletized lime.
