Hey Mr. West,
Thanks for sending those pics. Especially the second. What Tractor Supply carries is obviously a different brand, but I haven't seen the actual ingredients on it yet. I was looking at the Soil Doctor in a powder form from Lowe's also. Both are Calcium/magnesium carbonate blends. Now I can compare labels to see which has the highest calcium content and hopefully lowest magnesium. I don't think the Mag level will hurt me any as my hardness has been immeasurable on a litmus stick. Biggest difference I can readily see is TS sells 50# sacks for $.50 less than the Lowe's Soil Doctor 40# sack. But if Soil Doctor has higher calcium content, it may still be a better buy. I think I'll only need about 500#. If I need more, I can add some later. I'll know later today.
