Straight out the cow fat free...right. There is no such thing as fat free "raw" milk. milk provides very little Ca...it is mostly water. I want the fat.
Right. I meant to say "grass fed" milk, which is also "raw" or "whole" milk, with the fat/cream on top , which could be skimmed off, but there would be no point in buying it for this purpose, as skim milk works for the purpose stated. However, you could use raw milk with the cream/fat skimmed off the top. Just don't spray fat on plants as it gets rancid.
You want the fat for your health, but you don't want it on your plants. Sorry for the misinformation.
