Ok so lime is going down but I have been wondering about using limestone sand for some time. Our soil has a considerable amount of shale. I had 40 acres of timber cut 10 years ago on another parcel I own. The logger used 3/4 (#57s) limestone gravel. Grass and clover grows well in these areas.

What if I was to spread limestone sand instead of normal lime. Would it tend to stay longer and make for more availble soil ammendment.

I assume that by Limestone sand you mean fine ground limestone. If that is the case it will break down slower but last longer. I think it is a matter of grain size.

the ENM would be alot lower and you wouldn't get the results from it as you do the lime as it won't all disolve it may over several yrs but I really doubt it
the ENM is based on how fine the lime is ground and the finer it is ground the higher the enm and the better results you have

if you have lime that is a 400 ENM then you will have to use 1 1/2 times more of it than you do lime that tests at 600 ENM
