The basic research I have discovered.........9:1 ratio depending on diet is the scientific rate for diluting human urine. If the urine contains nitrogen, phosphorus and or potassium.......minus medications, is this a accurate hypothesis. Does urine change the pH since urine is acidic. Salinic compounds effects the pH, so is human urine safer to use at diluted rates. I am curious if we can start a discussion based on the facts and uses in Agriculture, growing, lawns etc. We are all in ability to contain these wastes as long as we can harbor and use the correct ratio's. I am in learning mode, so please understand that common inorganic fertilizer's is all I know. I am willing to learn more from real people rather than staged information for the masses.
