I truly apologize for getting testy, sorry.
I merely thought that having carried so many organic products the store might have known a little more about them.
And I do agree with everything you say, Dchall...wholeheartedly. I do have access to horse stables and cow pastures for that matter but wouldn't both horses and cows have medicines, etc. in their system as well? I am not a rancher, of any sort, but it seems to me that chemicals might be in their system as well. I am sure you know more about this than me so I will leave it up to you for information on if these chemicals would make it into their excrement as well.
By the way, I have beautiful grass that does not have chemicals used on it in any way. The vast majority of the time I leave it on the lawn after cutting it. But, after the most recent rain it has really taken off so much that I have to cut it about every five days just to be able to keep it in control. So, I used some of it to kick start my compost piles. My 3 compost piles are so hot now that they that they look like they are smoking and about to catch on fire.
I know it is steam but to the neighbors, it is very deceiving. It just took some moist greens to get them going good.
