Make a bone grinder for the garden

In all this, the evocation of the "link" between this enormous stock, but inaccessible to plants, and plants is therefore missing: these are the mycorrhizae!

How then to explain the increasing deficiency in phosphorus from forests. http://www.onf.fr/renecofor/sommaire/re ... index.html

Like another lazy gardener who writes just the opposite ??

Ground bone is not your friend!

be careful, he is speaking here not of whole bone only mechanically ground, but of an industrial by-product obtained after chemical treatment of the bones with the main aim of making gelatin: the name ground bone is completely misleading ... can be a very soluble product

"Ground bone" is the name in Quebec of what we call here "bone powder" http://www.canac.ca/fr/product/saisonni ... 49820.aspx

my chemistry knowledge is not precise enough to be sure but i see a story of acid rain coming

a phosphorus salt like calcium phosphate is not very soluble ... if you mix with sulfuric acid it makes calcium sulfate (plaster) and releases phosphoric acid, very soluble which will settle other rock in the basement so will be lost for the surface

same story with N02 which turns into nitric acid in the atmosphere and does the same kind of reaction on phosphate

spreading the ash in the forest is a double good idea: it puts the phosphorus in a place where it is useful ... 2nd effect it brings lime which is basic so neutralizes the acids fallen from the sky before it does bad effect

there are some who criticize the spreading of ash because there are lots of toxic things ... but it is only a concentric effect: all the mineral products of a tree are found concentrated in one low volume, so toxic natural product in low concentration in nature are found concentrated in the ash ... it will be diluted again if dispersed properly

I find it strange in the last link to talk about the effect of nitrogen as if it were an acid ... nitrogen is everywhere in the air and it is neither acid nor basic

there are 2 completely different chemicals based on nitrogen: nitric acid, becoming nitrate when it dissolves in rock ... and ammonia becoming ammonia when it dissolves in water: it is basic! the reverse of nitric acid

we can even make a salt with nitric acid and ammonia: ammonium nitrate for chemists ... amonitrate for farmers ... it looks like it was done on purpose to use different words in agriculture for prevent understanding

This is an excellent article, and I have repeatedly pointed out the danger of the practice of reducing wooden menus to heating pads. It will be difficult in the long term to prevent this untimely form of exploitation, since it has many advantages from the point of view of implementation: very significant reduction in work (no delimbing), slight increase in the volume harvested (depending on the nature of the stands) and reduction of drying time (evaporation by the leaves).

[izentrop]

Yeah, well, we're bad! It is not due to over-exploitation of wood.

If I understand correctly, as with eutrophication in water, it is the excess of nitrogen in the atmosphere in the form of nitrous oxide (N2O) http://www.planetoscope.com/atmosphere/ ... phere.html which causes the phosphorus to monopolize the soil. It's not just the use of phosphates in detergents, since eutrophication continues.

The exploitation of wood represents the most direct form of export and therefore of phosphorus loss for the ecosystem, but other forms exist and are linked to the acidification and eutrophication of the environment. Eutrophication corresponds to excessive inputs of nitrogen into the environment. This contribution contributes to the stimulation of growth (with the increase in atmospheric CO2 and the increase in the annual average temperature) and simultaneously increases the needs of all the nutritive elements which can then become limiting according to their availability in the soil.

Another link that confirms that excess nitrogen is the problem:

... a good majority of the excess nitrogen present in our ecosystems is triggered by an increase of around 800% of nitrogen fertilizer during the period 1960-2000.

The improper use of nitrogen fertilizers worldwide is also responsible for this excess. Some 60% of the nitrogen contained in fertilizers never gets incorporated into plants and is eliminated from the roots and then contaminates rivers, lakes, aquifers and coastal regions through the process of eutrophication (process triggered by an excess of nutrients responsible for the depletion of oxygen in rivers, thus leading to the death of all animal life).

In terms of atmospheric events, the researchers explain that nitrogen oxide is a greenhouse gas whose warming potential is 300 times greater (per molecule) than that of carbon dioxide. In addition, nitrogen oxide simply removes stratospheric ozone, which protects our planet from ultraviolet radiation.

Lots of things that should be "synthesized", put into perspective and not just added.

Eutrophication is a very particular phenomenon of "suffocation" of a body of water by the mechanisms described: too much nitrogen, devouring growth of plants (algae, etc.), excessive absorption of others. elements ...

But the leaching of excess nitrogen is much more general, without resulting in eutrophication. The proof: nitrates in drinking water (therefore tablecloths ...).

In this case, the P does not "dissipate" from the ecosystems in question: it is "re-organized" = incorporated into the organic matter. And will be released again when it breaks down. So it's just a "sequestration" ...

[...] who confirmed that excess nitrogen is the problem

Serious? It's nothing personal but just an observation: it's been a while since I wanted to say what Did67 just specified. For someone who is a fan of chemistry and biology (we can't know everything), you "confirms"always a lot of things but I think it is dangerous to listen to you, because not being able to distinguish the true from the false (do you lack experience?), you often bring it back inappropriately.

It's not just the use of phosphates in detergents, since eutrophication continues.

Uh, but what a report for allotment gardens. Chatelot rightly said that phosphates are salts. You still haven't understood what a salt is in chemistry. It's super stable! We may repeat it to you. It just has nothing to do with it. The problem is not there, we need things globally, fine interactions, coughed, coughed ... to be able to "synthesize" as Did67 rightly said

It is for example funny that you are concerned here with phosphorus whereas in the case of Chernobyl when it becomes radioactive, you persist in saying that "finally it would not be so dangerous for the animal kingdom since it would adapt". And when it is in salt form then? Do you know at least all the damage that radioactivity does as biochemical (and not just radiological) damage?

Finally for this thread, you bring back your pseudo- "science" but you who struggle to always come back to the load with the "doses", for once they are insignificant (more than organic garden with permaculture) you add more endlessly with questions of pollution and a whole mess which is out of proportion I find.

PS: On the (bio) chemical level, how can you explain / demonstrate / justify: all your / these contradictions?
