Description of the experimental groups of the long-term field experiment used for sampling to obtain the dataset.

Experimental group	Description of the experimental group
Control	Control group, soil to which nothing was applied
Background	Soil limed at the beginning of the first rotation of the crop rotation. Background for experimental groups with fertilizer application, which were also limed
PK	Phosphorus and potassium fertilizers were applied to the soil in one dose per rotation: double superphosphate (P2O5 single dose 340 kg/ha), potassium salt (KCl 360 kg/ha)
1NPK	Nitrogen, phosphorus and potassium fertilizers were applied to the soil in one dose per rotation: double superphosphate (P2O5 single dose 340 kg/ha per rotation), potassium salt (KCl 360 kg/ha)
2NPK	Nitrogen, phosphorus and potassium fertilizers were applied to the soil in double dose per rotation: ammonium nitrate (NH4NO3 680 kg/ha per rotation), double superphosphate (P2O5 680 kg/ha), potassium salt (KCl 720kg/ha)
Manure	Cattle manure was applied to the soil (60 t/ha, 6.2 kg N, 3.2 kg P2O5, 6.1 kg K2O in 1 t of manure)
Manure+PK	Cattle manure was applied to the soil (60 t/ha) in combination with phosphorus and potassium fertilizers in one dose per rotation
Manure+1NPK	Cattle manure was applied to the soil (60 t/ha) in combination with nitrogen (340 kg/ha), phosphorus (340 kg/ha) and potassium fertilizers in one dose per rotation
Manure+2NPK	Cattle manure was applied to the soil (60 t/ha) in combination with nitrogen, phosphorus and potassium fertilizers in double dose per rotation
