HI Jim, Is all urine the same. Seems like human is more alkaline - at least it seems that salts (& calcium?) deposit or settle out of human urine.

Jerry asked, "Does horse urine really make soil acid, as several have
said?"

Fresh urine tends to be acidic and is 95% water and 2.5% urea. The
average pH of urea is 8.8. Urea in soil is converted to ammonium (NH4)
and/or ammonia (NH3) which is rapidly converted to nitrate (NO3) which is in
the form taken up by plants. Its effect on soil pH is fleeting and almost
momentary.
