| description | The aim of this paper has been to determine the importance of the strip-till method for the content of carbon and the quality of organic matter as compared with plough and ploughless tillage. The question to answer has been to what extent strip-till can contribute to carbon sequestration and thus be part of the strategy of counteracting climate change. The research involved soil where conventional tillage (CT), strip-till (ST), and reduced tillage (RT) were applied. These systems differ completely in the way they affect the post-harvest residue, i.e., “plant residue management”. For air-dry soil samples, the following analyses were made: the content of total organic carbon (TOC) and total nitrogen (Nt), content of dissolved organic carbon (DOC) and dissolved nitrogen (DNt), and the fractional composition of humus. In the surface layer the content of TOC ranged from 11.96 (CT) to 13.88 g kg<sup>−1</sup> (RT) and DOC ranged from 209.9 (CT) to 230.5 mg kg<sup>−1</sup> (ST). The share of the fraction of fluvic acids (0–15 cm layer) changed from 15.51% (RT) to 18.81% (ST), the share of the fraction of humic acids was 9.36% (ST) to 11.60%, and humins were 68.90% (CT) to 72.6% (RT). These results demonstrated that the tillage system determines the properties of the organic matter of soil. In the surface layer (0–15 cm) and in the 30–50 cm layer the properties of the soil organic matter under strip-till had a greater similarity to the soil under ploughless tillage than under conventional tillage. Ploughless tillage and strip-till considerably limited the leaching of carbon and nitrogen from the surface layer to the 30–50 cm layer. Strip-till, similarly to ploughless tillage, is the tillage method which can be crucial for the process of carbon sequestration. |
