Aglime, barn lime, powdered lime, pulverized lime, garden lime, pellitized lime is all ground limestone mined out of a quarry and ground up. What matters is how fine it is ground up, and how much carbonates there are in the limestone. The carbonate is what nutralizes acid soil and may be 40% of limestone composition. Most the carbonate will be calcium carbonate, and 1 to 15% might be magnesium carbonate. Pure magnesium carbonate is "dolomite". When the limestone contains over 5% magnesium carbonate it may be called "dolomitic lime". Composition depends on where the limestone was quarried, and sometimes even what part of the quarry it came from.

Pellitized lime is just powdered lime with a binder addedto form tiny pellets, making it easy to spread in any conventional spreader. The question is how much weight is lime, and how much did the binder dilute the lime you want to spread? For all practical purposes, pelletized lime is powdered lime with a binder. The smaller the particle, the quicker it reacts with the soil. How long the effect lasts depends on the soil, organic content, buffering capacity, ect.

There is no standard for ground limestone where Aglime is this, and barn lime = that ....it varies all over the map. Particle size, and lime composition are the main criteria. There are websites out there that will expain the particle size and composition formulas for application rates.

The important thing is to spread lime, and spread what you have the ability to spread. If your plots are less than an acre, powdered bagged lime is often easier to spread by hand than through a spreader. Tear the bag open and fling it around .... yes it is dusty.

LIme leaches into the soil very, very, very slowly. You want to disk it in before planting when ever possible ... same with potassium and phosphorus.
