The article presents data on the shift in the accumulation amount of the total of chlorophyll a+b, flavonoids and the nitrogen status of plants with different doses of organic, organomineral and mineral fertiliser in a five-field grain-coupled crop rotation. The revealed patterns of changes in plant nitrogen nutrition levels allow us to conclude that only soft winter wheat and maize in the Belgorod region have a positive impact on the after-effects of organic fertilisers. Only in the case of wheat is the difference between the doses of the mineral and organic fertilisers important. Increased mineral fertiliser doses contribute to accumulated soil nitrogen accumulation and as a consequence, to a decrease in plant nitrogen status.
