Vegetables can resist to a point ...
I wonder if a vegetable that can resist (for example) -2 will resist
several -2 in a row?
Ah hard soil has a hard life: repeat over and over again that plants make their life there just as in loose soil, as you say what matters is that the soil is alive.
And anyway the more he lives and the more he becomes relaxed without you being able to do anything about it and especially without you doing anything.
The fada "trépigne" (historical expression) I love: it's going to talk
We can see what we like to see: excellent
And to make ends meet with the hard / soft soil: we produce the environment that suits us more than crops
In these cold weather and outdoors, could tarpaulin not allow the continuation of bacterial activity on the surface or at least bring this bacterial activity “up” as close as possible to the surface?
And if I trust the potatoes kept on the ground but under the hay and which do not freeze by -10 ... except for a tarpaulin, can't the hay constitute this covering and allow the continuation of this activity of surface even in cold weather?
By always relying on the potatoes that, once again this year we keep on site under the hay, would it not (disregarding predators) be possible to do the same with raves?
I intervene because these are notions that I often handle, but in climbing / mountaineering
It must be a minimum transposable in agriculture! We are talking about surface gel and deep gel.
Surface freeze = only the first mm are frozen
Deep frost = the frost is long and strong enough for the temperature to drop below 0 for several cm (of rock!)
Clearly, when it freezes at -2 ° C overnight, it's just surface freezing. Especially since the biological activity will regulate the temperature. I have already noticed, at altitude, that my breathing was steaming in the "open air" but no longer under a small piece of forest. I deduced that in the forest, it was hotter, yet in the same place and at the same altitude.
I would tend to say that if the soil can warm up during the day, most plants will get out of it because the soil will never actually drop below 0. On the other hand, if the temperature does not take off again during the day, there, the ground itself ends up freezing, and suddenly the entire regulation system falls flat.
The tarpaulin helps if there is sunlight, enough regardless of the temperature (it feels like a squeeze).
Hay adds a layer of insulation, of thermal buffer: it will smooth the temperature variations (in both directions).
Voilou, some thoughts.
