RE: Lime - Pellett vs. Powder
To spread pulverized lime you will need a specialized spreader (with and auger to keep lime from packing in. Pelletalized lime is can be spread with an ATV or other type of broadcast seeders. Usually, if you are getting bulk lime, they will drop a spreader with it (at least where I am). If you get a speader, go with the pulverized.
As far as a ton of lime being equal to a ton of lime - that is not necessarily the case. Yes a ton is a ton, but there is a thing called %ENV, which simply is how "strong" the lime is. So if you get a ton of 50% ENV lime and a ton of 100% ENV lime, the 100% has twice as much effectiveness. To put it another way, if your soil result says you need a ton of lime/ac. and you get the 50% ENV variety, you will need to apply 2 ton/ac.
