Urinal: is it really economical?

[izentrop]

Otherwise the urine at my house ends like this:

Uh what is this system?

I have dry separating toilets and since I did not want to send the urine to my septic tank,
I collect it in 20 liter cans which I store in the garden where I water my compost with it. It makes me less material to transport and the overflow we still go to the pit in case of no time.

The simplest solution, piss in a plastic milk bottle.
Well, obviously it doesn't work for women.

Then when it is full direction the garden.

Normally not in winter so as not to pollute.

Approximately every 15 days, when the 3 cans are full> wheelbarrow> garden shed. These salvaged stove oil cans have the advantage of being stackable. I find it hard to imagine storing 60 bottles for the same quantity.

What is the difference with summer?

In winter, nitrogen leaches into the aquifer through leaching and the inactive vegetation does not act as a nitrate trap ...
Conclusion: only piss in summer!

OK, thanks for the explanation.

Bizarre all the same, the sites which speak of using urine as fertilizer do not say to avoid in winter.

[Ahmed]

Perhaps they are content with general considerations, without a somewhat detailed understanding of agronomic mechanisms ...

Note: my previous answer was a bit incomplete, in the sense that with low temperatures in winter (which is not always the case) the nitrifying bacteria are not very active: their action is basically stalled over the period active vegetation, which is great!

Autumn still seems more dangerous to me than winter ...

Because then the ground is still warm, and the bacteria are working well. Urea is transformed into ammonium by a first family of bacteria. Then ammonium nitrites by another, then nitrites into nitrates, leachable, by yet another ... It's crazy what it feeds, good piss!

In winter, the floor eventually cools down, and like in a fridge, it all lingers ...

In autumn, often the soil is bare (or covered with plants which hardly grow anymore) ...

But indeed, the majority of "green" sites do not take nitrates into account - since it is natural, it is well known, there is no danger. It's like the (bad) combustion of poorly seasoned wood in a bad draft-regulated stove. An ecological disaster next to which an Airbus A380 is almost an inhaler for babies! But it's green. And we brag about it ...

What is the difference with summer?

In summer the plants absorb everything, while in winter they are at rest.
If you have an area large enough to spread, that your soil is not sandy, that you are not in the catchment area, it will, otherwise, risk of leaching and loss of nitrogen.
And then after an airless storage of a few months the urine is hygienized. https://www.rae-intestinale.fr/app/down ... 1500751868

It is also recommended to recover the leachate from the compost of the dry toilets. https://www.rae-intestinale.fr/app/down ... 1535475257

Ps: I see that I am not alone in having answered you

I don't have waterproof compost yet but it will come and the experience of lactofermentationwith

I'm not in the catchment area, fortunately.
