abstract = {Crop production often leads to soil organic carbon (SOC)
losses. However, under good management practice it is
possible to maintain and even re-accumulate SOC. We
evaluated how different cropland management techniques
affected SOC stocks in the topsoil (0–30 cm depth) of 10
long-term experiments (LTE) in Germany. We found that SOC
stocks were particularly enhanced by mineral fertilization
and organic amendments like straw incorporation and to a
smaller degree by irrigation, but only slightly affected by
the choice of preceding crops. In agreement with global
meta-analyses, liming and reduced tillage had little or even
negative effects on SOC storage, but effects also depended
on fertilization. Management effects on SOC stocks were
dependent on soil texture: sandy soils showed the lowest SOC
stocks of 20.9 ± 2.3 (standard error of the mean) Mg ha−
1, but exhibited the largest relative response to different
management options. Annual changes in SOC stocks ranged from
− 3.0 ‰ with no mineral N fertilization, to + 6.1 ‰
with farmyard manure application, using the
mineral-fertilized and limed treatment as reference. Even
higher rates of up to + 10.6 ‰ yr− 1 were reached with
the combination of irrigation and straw incorporation. Note
that the contribution of organic amendments to SOC accrual
and thus to climate change mitigation must be adjusted for
reduction in SOC at sites from which straw was removed.
Overall, the potential of agricultural management to
influence and enhance SOC stocks is significant. This
potential is controlled by soil type and land-use duration,
is largest for sandy soils with overall lowest SOC stocks,
and is characterized by antagonistic and synergistic effects
of different management practices.},
