No, not solved: my calculation takes a slice of soil 20 cm, basically the depth of plowing. Redefining the mulch only spreads the misery in the few cm involved. As soon as the MO decomposes, the copper is there, in the superficial horizon.

A few cm, it depends
a different distribution of copper according to the organs, ranging from a high concentration in the roots to a more modulated concentration in the aerial parts. https://prodinra.inra.fr/?locale=es#!Co ... ice:198044
Without tillage there is in fact a distribution also in depth, not to mention the work of burrowers.

Finally, as seen on the GIS map, a Bordeaux mixture in the Bordeaux region should not be a problem if soil analyzes and doses are well managed. : Wink:

I no longer have the references at hand, but I remember a serious study (INRA ???) which showed that 80 or 90% of the copper brought to high dose in viticulture it seems to me, was found in the 10 first cm.

For my calculation, I took 20 cm.

In the summary you put, it is not clear how copper is applied. Obviously, it seems to be potted trials on cuttings... Very peculiar. I guess this is the measure of foliar treatments (which can have a phytotoxic effect). The doses are in μM (micro-moles, but μM by what? Liter? Foot? Kg?) ... Unexploitable like that. I did not find the report in extenso to understand.

There is a lot of data in this thesis, with page 25, the soil contents (which interest me), depending on whether it is an uncontaminated soil, contaminated soil plowed (the front actually goes down but it is not more reassuring, even if it is a little less marked - dilution?) or contaminated soil not plowed. We see that we cross the toxic 150 ppm for worms, of course for mushrooms ... And that we are in an order of magnitude having nothing to do with the needs! No need to argue about it to defend copper!

index.php? mark_notification = 107168 & hash = c0528c91


PS: I answer, but you note that my intention was to underline the delicate slip of the marketing, which already acts that the copper is also toxic (and thus which dissimulates this in the eyes of the consumer not very curious, but which could have been alerted by the media!)

I wonder for some time already about the virtual absence of blackbirds in the kitchen garden behind me ... I see constantly magpies, crows, small passerines ... but no more merle!

and now the report is included in an article in my journal ... with the explanation https://www.republicain-lorrain.fr/edit ... merle-noir

I did not know that the blackbird was the
friend of the gardener, for his appetence for slugs
. Otherwise I always cross here and I hope that it will last despite this virus.

I had not been careful, but now that you say it!

I attend battles between magpies and woodpeckers, in the meadow in front of my window ...

In the garden, it's calm. But hey, I'm not planting right now, so I'm not paying attention!

I noticed too.

They used to return the mulch in search of worms, but I also have many more magpies than before ... I put it on the count of the greedy magpies of eggs of blackbirds, they must all likewise participate in the hecatomb.

Usually in January, I often attended male fights for a female ... Still not seen this year. :?:

please

and another for everyone, I have a little bit (2 m2) the lawn that I want to turn into a kitchen garden, the problem this little end is north, but then north, behind the garden shed, what can I put? I had thought of wild strawberries ...

1) Asparagus: there were losses by mole rats; they like the roots a fleshy stink (called "claws"). The rest is developing well, even very well. A problem of stability. They should be guarded. If they were all there, I would stretch one of the wire mesh we use for the concrete slabs horizontally. The first two years, we do not harvest, to leave the products of photosynthesis to the claws for them to develop. Finally, when they are not covered, the spears are very quickly "hard". They must therefore be harvested as and when. Basically, it works.

2) I had very few times the "roots" (damaged) that I had planted at the end of 2017. Some have rotted. The 2018 drought has decimated others. And this fall, nothing screwed up.

This is therefore drifting.

But with minimal attention, it would work.

The plants must be "implanted" in the spring, not in the fall. May it make beautiful and big dandelions during the year.

A "black" point however: the leaves "scatter" in the hay; by harvesting, we lose. And it's a boring to clean !!! When I get down to it seriously, I think I'll force them in the cellar or under a black tarpaulin. So cultivation in rows, in hay. Collect the roots in the fall, place a cellar to force it. Or cover on site with black tarpaulin.

please
so for asparagus the next season should be the first harvest?
for the dandelions you would force that like endive wholesale?

and if not for my corner in the northern shadow of ideas?
