You can restore the soil after harvesting root crops using green manure.
Experienced gardeners recommend paying attention to legumes.
For example, peas, lentils or beans. They are ideal for sowing in August-September.
Thanks to them, the soil becomes nutritious, loose and airy, saturated with nitrogen.
You can also choose other green manures . Mustard and phacelia will enrich the soil perfectly. You can make a mixture of these plants.
They can be mown down before flowering or left until spring. In the latter case, you can save the soil from erosion and protect the area from deep soil freezing.
It is worth mentioning rapeseed separately, which usually has a powerful green mass, but at the same time grows poorly on highly moist soils.
It is better to sow such green manure after potatoes before mid-September. This crop, thanks to its developed roots, loosens the soil well and saves from soil erosion.
