is there any scientific data on animal dung and urine being used in organic farming? any quantification crop wise?

Yes, we can anlyze the dung and find out how much nutrients are available in it quantity vise. It has to be decomposed up to 80% before application and we can add all type of Bacteria into it before application, which will reduce the need of Chemical Fertilizer considerably.

We have developed a technic to develop these bacterias and can grow any crops without loosing productivity and financial loss.

THanks and regards
