the stuff I use all the time is this

Hi-Yield (brand)
horticultural hydrated lime

minimum guaranteed analysis
Calcium (CA)...................51%
Calcium Oxide (CaO).........72.5%
Mag Oxide (MgO).............0.45%
Cal Carb Equiv (CaCO3).....131.%
CalciumHydroxide (Ca(OH)2)...95.79%
E.N.P.............................130.35
E.N.V.............................130.35%

I dont get the percentages listed but this is what the bag says
I use about a cup in a big ass rubbermaid of compost and about 2 tablespoons in a simmering pot of wheat that makes about 10 qts

stuff works great
