Abstract
Temporary grasslands are recognized both for their ecological functions, such as nutrient cycling, soil quality, and also for their potential role within crop rotation frameworks. While many studies have shown the agronomic and environmental benefits of permanent grasslands, fewer have analysed the impact of temporary grassland phases as precursors, influencing coming crops in terms of system stability or yield. Results are often mixed or contradictory in the academic literature, due to methodological limitations or insufficient statistical power. The current long-term study (2008-2014) investigates the role of grassland as a precursor to suitable arable crops (potatoes, spring wheat, silage maize and forage turnips), on a rotation-based empiric design, focusing on temporal variability, yield fluctuations and the broader agronomical context in which these changes occur. Using multi-year data, we look at crop yield performance, and discuss results offering suggestions for future research. To account for structural yield differences among crops, yields were standardized within crop categories, allowing for a unified analytical framework. Results from factorial ANOVA models indicate that grassland phases contribute to yield stabilization rather than a uniform increase in production of other crops, with outcomes influenced by crop type and stationary area conditions. Our results suggest that grasslands have the potential to enhance system resilience and are valuable for sustainable crop production under increased environmental uncertainty.
