Abstract
Aims: The objective of this study was to investigate changes in soil total organic C (TOC), total nitrogen (TN), phosphorus (P) fractions, and microbial communitystructure during secondary succession after abandonmentof vineyards on calcareous soils.
Methods: Two chronosequences covering 200 years and differing in aspect and slope were established in Hungary, and the upper 10 cm of the mineral soils were studied.
Results: We found strong increases in TOC concentrations after land-use abandonment, especially at the south-exposed sites. The TOC/TN ratio increased by afactor of 1.3 in the south-west exposed chronosequence and by a factor of 1.6 in south exposed chronosequence. The concentration of labile P (NaHCO3-extractable P) diminished during the first 50 years after land-use abandonment,leading to low P availability at the later stages of the succession. The total organic P (TOP) concentration increased during the first 40 years after abandonment. At the later stages of succession, TOP concentrationsdecreased again, while the ratio of TOC/TOP increased continuously over 200 years. The ratio ofarbuscular-mycorrhizal-fungi-to-bacteria (AMF/bacteria)increased strongly during the first decade after abandonment of the vineyards.
Conclusions: Our study indicates that impacts of former cultivation on secondary ecosystems persisted for more than a century, and that especially P concentrations showed long lasting legacy effects.
