What do you mean?
I hope at least that our Alsatian gardener understands me.
I mean here that his garden produces the same same order of magnitude of vegetables as other cultivation method. for example 1kg of potato per m² and per year.
if it were 3 or 10 times less, it would be uninteresting: not to tire yourself out to have nothing, blah.
If it is, 3 times more, ah that would be nice. Nothing improbable or magical, photosynthesis converts less than 1% of light energy into biomass energy, there is room for improvement.
Is hay in great thickness every necessary necessary over time?
äie, I wrote incorrectly.
the question was: should we put back so much hay each year? A very thick layer?
Or a long-term improvement makes it possible to consider lowering the doses. For any poorly mastered process, we put too much at the beginning (such as treatment by amateur gardeners), and then we learn to do better.
Isn't the interest of hay that it is balanced in C / N?
To increase the carbon rate it would rather be boyat, no? And be patient ...
In the book "the vegetable garden of the sloth", the author if I remember correctly said measuring an increase in organic matter in the soil.
Other more carbonaceous materials also have this effect, perhaps faster, but with less nitrogen vegetables grow less well.
What would be the problem with this exploitation?
If we are wondering how to feed a population more widely with practices that improve the soil, the problem is to need a lot of surface. but this area of meadow does not appear to visitors or to anyone who wants to get started. So we can give the illusion of having found an abundant non-polluting and fatigue-free cultivation method, but by masking the fact that this requires a lot of surface area.
We often have this problem in terms of ecology, false solutions, such as agrofuels, well this has been known for a long time for this particular subject.
be careful, I am not saying that a vegetable patch with lots of hay is harmful like agrofuels.
You also speak of spontaneous grass which brings their energy - What do you mean?
to ask our author, he indicates that plants capture energy from the sun and give it back to the soil by decomposing, after which I do not want to modify his thinking.
Is it always related to the supply of hay or do you want to talk about something else?
Hay, or any plant that decomposes quickly so not too woody I can
In what way are the vegetable gardens not nourishing?
they are on a small scale. A good 500m² vegetable garden can feed one person with vegetables, maybe two, people who practice autarky might tell us, but this is rare. That is to say that they have no external contributions (purchase in the trade of cereals, bread, legumes from field crops and not from the garden) or negligible contributions
In short. A good small soup of 500m², ok but you need 1500 to 2500m² of meadow nearby to cover.
In France, there is 5000 m² cultivable per inhabitant, it is still happening.
The durability of what?
From an artificial food production system: garden, cultivated field.
And in the case shared by the book, that would be "organic", productive and not exhausting.
It being understood that a forest for hunting is obviously sustainable, but it feeds 10 to 100 times less people per km², anthropogenic food production systems exist for us to be so numerous on earth, in directing plant production as best we can towards what interests us, us humans who think and discuss, but who do not eat wood (everything would have been easier in this case).
I noticed from your book that what comes out of mines alter in the long run - What do you mean?
damn, I wrote wrong.
what comes out of the mines are metals, which are dispersed on the surface of the earth, either for agriculture voluntarily: copper as phytosanitary, involuntarily: cadmium bound to fertilizers, or by other processes such as lead which existed for gasoline, which is found in the air and then in the ground. it does not disappear, it does not fit all in the ocean, it accumulates in part in the earth, without much means of diminishing in the short term. And some metals can reach concentrations that inhibit biological processes.
