Well all the crops we eat have been urine on them.Brids fly over and land on them,wild animals run through the crops,deer,bears,dogs, cats,possum,ect.
The earth buffer the ph in the open.I dont want any pee pee pot.I"ll just use the store brought nitrogen.Your body is like a sponge,get it on you,you got it in you. Peace and Happy Turkey Day
