Most green-manure crops need at least four to six weeks in the ground after incorporation before the following crop can be sown without risk of nitrogen immobilisation.
Fast-establishing species like phacelia or white mustard can be sown as late as early October in central Poland and still produce useful biomass before the first hard frost.
Legume covers such as common vetch or crimson clover fix atmospheric nitrogen through root nodule bacteria, reducing dependence on external nitrogen inputs in the following season.
