Short summary
Winter warming increases freeze-thaw cycles in grasslands, yet its consequences for N cycling remain unclear. Using a ¹⁵N tracer, we found that frequent freeze-thaw cycles release N, but limit its availability to most plants, thereby benefiting soil microbes. Some cold-adapted grasses were still able to obtain N. These findings suggest that winter climate change may reshape grassland community structure and productivity.
