This has two consequences:
a) there won't be much left for the next season - and that can upset you; in return, the life of the soil will already be improved and a start of deterioration may occur ...
b) mineralization will begin, with nitrification; risk of leaching of these nitrates during the winter, therefore pollution; So yes, it is then necessary to install "CIPAN" (nitrate trap crops), such as mustard or buckwheat (non-legumes).
If you only put out at winter, you must indeed protect, otherwise it will break down into a heap - in short, compost! Much of the energy will be gone in the spring. You will have the minerals that have not been leached and prehumic or humic substances ...
OK, thank you Didier.
Indeed, this is what I understood.
If I sow a green manure in the hay, can I sow it directly (on the fly), or in a row like we would for any vegetable? Or else, do I sow first and then spread the hay?
