That prices for pellitized lime and the ag lime are really cheap. I am in upstate NY and spread that stuff with one of those big floater trucks. The truck holds around 10ton. We get around $260 a ton for pelletized lime picked up, $30 a ton for ag lime picked up, $40 a ton spread for ag lime from store. If you order 40 ton or more we can have it farm dumped and you load with your tractor and we spread for aroud $30-32 a ton. I can spread around 300-400 ton a day with the big truck if someone it loading me. Also where do you get your ag lime from and what is the (env), being that cheap I would think it is on the low side, which means you have to put more on per acre.
As for the pelletized lime there is a big difference between that and ag lime. Pelletized is 100% env. You get 100% becuase it goes through a process where it is crushed very fine and then baked in to a pellet. This makes it easier to put down because it is in a pellet form and spreads through a reagular spreader. It cost more for the convienence but is only good for 1 year. This is because it raises your ph quickly last for around 6 - 8 months and thats it.
The ag lime is anywhere from 30 - 70% env depending where you get it from and how fine it is crushed. Ag lime is good for around 3 or more years, but it takes around 4 - 6 months to raise your PH. This is why for a spring seeding you should spread in fall and for fall seeding you shoud spread in spring.
Great pics of the plowing, disking, and lime spreading. Looks like lots of fun.
