Here's another one to add to the pile (so to speak)
www.ecosanres.org/PDF%20files/Fact_sheets/ESR6lowres.pdf

"Urine is a high quality, low-cost alternative to commercial fertilizers.
It is especially rich in nitrogen and also contains substantial amounts of

phosphorus and potassium. The fertilizing effect is rapid and the
nutrients are best utilized if the urine is applied prior to sowing and up

until two-thirds of the period between sowing and harvest. It can be
applied pure or diluted. To avoid odour, foliar burns and the loss of
ammonia, the urine should be applied close to the soil and incorporated
into the soil as soon as possible."

"If no local recommendations can be obtained, a general rule of thumb is to

apply the urine produced by one person during one day (24 hours) to one
square metre of land per growing season (crop). The urine from one person
will thus be enough to fertilize 300-400 m2 of crop per year and even up
to 600 m2, if dosed to replace the phosphorus removed by the crop. For
most crops, the maximum application rate before risking toxic effects is
at least four times the dose above."


Here's another point

"Human food contains considerable amounts of nutrients originating from
plants. Only minute amounts of the plant nutrients are absorbed by and
retained in the growing human body – the remainder leaving the body as
excreta."

Question:
If that's the case, then isn't recycling human waste a critical key to
sustainable growing? What is the cost in time and money to replace soil
nutrients lost because of human waste that's not returned to the soil?
