The land after harvesting potatoes always needs restoration and a special approach.
Therefore, one of the best options is planting green manure.
What options can be considered?
Legumes
This is a great option for soil restoration. You can choose any representatives of this group, but experienced gardeners really appreciate lupine.
It needs to be planted right now, as it takes about 60 days to complete its cycle.
Cereals
In this category, rye is an excellent choice, as it does not allow nematodes to remain in the soil. However, it is necessary to have time to dig it into the soil so as not to provoke the appearance of wireworms.
You can also pay attention to oats: you can safely sow it in September. The soil will be healthy. You can mix this green manure with legumes for a more pronounced effect.
Phacelia and buckwheat should be sown right now, otherwise it will be useless. After them, the soil will become incredibly nutritious. It will also reduce the number of weeds.
