Abstract | Long-term soil organic matter (SOM) and nutrient dynamics following different crop residue management were studied in two field experiments in Austria: in Marchfeld since 1982 and in Alpenvorland since 1986. The turnover of SOM was modeled with the CCB (CANDY carbon balance) model. SOM parameters such as soil organic carbon (SOC), active C (KMnO4), total nitrogen (Nt), and the N-mineralization potential increased significantly following crop residue incorporation. C/N ratios, however, did not differ significantly. Plant-available potassium (K) increased by 40% (Alpenvorland) and 50% (Marchfeld), magnesium (Mg) only in Marchfeld (+ 9.7%), and no effect was evident for phosphorus at either site. Our results showed a strong agreement between measured and simulated SOC values. SOC can be maintained in the long term with the incorporation of crop residues, but it will decrease with annual removal. |
