Here's my advice,.. do what you can afford to do. If you have a soil test and it calls for 3 ton of lime per acre,.. you need 3 ton of ag lime or pellet lime. Pellet lime is much more costly,.. but the only way some of us can get it in to our plots. SO,.. do what you can!! What i do is buy by the pallet. 60 bags on a pallet at 40 lbs each,.. 2400 lbs. If your soil test called for 3 ton,.. your applying around 1/3 the recommendation. If the ph value of your soil was 5.5 ,.. then 3 ton will get you at neutral,..7.0. By applying 1/3 the lime recommendation you raise the ph value up by 1/3,.. which would be around 6.0. You now know what ever seed you put in the ground should work in soil with a oph value of 6.0 give or take .20. At 6.0,.. you can produce a nice plot if you use the correct seed with the right amount of fertilizer,..BUT,.. your goal should be to get the soil at 7.0 as time and money allows.
Hope that helped!!
