text: Agriculture is a major contributor to nitrate groundwater contamination. Hence,
farmers are demanded to reduce the environmental impact but simultaneously must
provide sufficient food products. One important building block for this "sustainable
intensification" are appropriate cropping strategies. The potential of modified
crop rotations was evaluated in a high-yielding environment in Northern Germany.
Therefore, in five consecutive growing seasons (2016/2017 - 2020/2021) three crop
rotations were grown in a field trial and compared with respect to agronomic (cereal
unit), economic (gross margin) and environmental (N surplus) parameters. A standard
crop rotation, typical for the region of the study, was compared with rearranged
and augmented crop rotations. Therefore, crops with a high autumnal N uptake (winter
oilseed rape and catch crops) were grown after crops with typically high soil
mineral N (SMN) amounts after harvest (faba bean and winter oilseed rape). Due
to the change of preceding and subsequent crops, an increased N transfer was supposed
to prevent N from leaching and a lower N fertilizer demand of the subsequent crop
was expected. On average, the modified crop rotations achieved significantly higher
cereal units (9.3 and 10.8 t center dot ha -1) compared to the local crop rotation
(8.5 t center dot ha -1). The gross margin of the local crop rotation was 1474
euro center dot ha- 1 and the other crop rotations maintained (1443 euro center
dot ha -1) or significantly increased (1572 euro center dot ha -1) this value,
respectively. The local crop rotation had a N surplus of 47 kg N center dot ha
-1. In contrast, the N surplus of the modified crop rotations was significantly
lower (10 and 28 kg N center dot ha -1). In summary, the results showed that a
thoughtful rearrangement of crop rotations is an appropriate measure to simultaneously
improve yields and gross margins with less unfavorable environmental impacts.
