Abstract: The subject of this study was the analysis of the soil organic matter (SOM) management in Polish agriculture in 2017-2019. The comparative analysis in spatial arrangement was carried out at the level of polish voivodeships. SOM balance was prepared in a simplified way, using it is degradation and reproduction coefficients proposed by Eich and Kundler. During 2017-2019, the balance of SOM was at level of 0.07 t DM/ha arable land (ArL). Positive balance of SOM was found in most voivodeships of Poland, and by far the highest in two voivodeships: Podlaskie and Warmińsko-Mazurskie, where manure and slurry resources were the largest. The negative SOM balance ranged from -0.02 t DM/ha ArL in Lubuskie to -0.14 t DM/ha ArL in Dolnośląskie, and the main reason for this was low natural fertilizer supply. In those voivodships the amount of ploughed-in plant material was insufficient to cover the losses of SOM caused by plant cultivation. The analysis of SOM management confirmed high polarisation between individual voivodships, together with the processes of extensification of production organisation (specialisation), with a simultaneous increase in it is intensity and scale of concentration.
