Hello,
These are the famous cuckoo sputum, caused by leafhoppers.

It is always more ethical than advising people not to take B12.

2) There are other products providing Mg: magnesia, magnesian lime, etc ... => blah (pH 7.8!) It would be necessary to know if the S is also low. => suspicion (alliates in small form) Or if the pH is alkaline ??? There, the sulphate would have its utility to lower the pH !!!! => yes (pH 7.8!) 3) I do not see ...

I asked for confirmation, but I think that there is a slip in the commentary at the end: I do not think that it is necessary to be careful not to lower the Mg content, well on the contrary; it is out of the ordinary from above; the K is also out of the ordinary from above, but proportionally less; therefore ...

it seems to me all the same very unlikely that with an OM content close to 5% you will suffer from a sulfur deficiency. : lol: Sure. But putting sulfur at the heart (sorry ...) of the problem has the advantage of being easy to verify and of not presenting any risk. The leeks start to grow, bingo; ...

Ah, thank you very much, so we can suffer from suffering in peace.

I come back to the story of sulfur which: 1 / is a necessary element and often insufficiently present since our rains no longer bring any. 2 / is a fungicide Problem: if we add it to the plants, don't we run the risk of harming the fungi that we want to promote elsewhere? J ...

Vegetables - those that want to grow well - are tasty. I would only remember that. As a result you regularly bring compost, balance all your kitchen waste, you try to keep it all moist all the time, even when it's not cultivated and in my opinion basta: Absolumen ...

No, I don't have the grain size. They actually do their calculations as follows: Fine earth base: 3000 T / ha or 20 cm deep If I put 3T on 100m², it's as if I put 300g (or 3 handfuls of wet sand) on a 10x10cm square. The question is therefore whether these 300g once ...
