In my country, many people are cultivators, I advise them to do a system called closing the loop.
Let me explain "Closing the loop" here: In Ecological Sanitation, when people talk about "closing the loop", they mean closing
the loop between sanitation and agriculture (chiefly with respect to returning nutrients and organic matter contained in excreta back to the soil). Make sure: The
idea is to fertiliser the soil, not the plant.The plant roots will get the nitrogen from the urine via the soil.
Urine is a complete fertiliser, if you urinate directly on a
plant, urine may have a detrimental
effect on the leaves and flowers of plants.
My thanks to all who want to know and to use "closing the loop".
