ABSTRACT Global climate change and agricultural practices have increased atmospheric nitrogen (N) deposition, significantly affecting the cycling process in grasslands. The impact of different N forms on key soil enzyme activities involved nitrification, particularly saline‐alkali grasslands Hexi Corridor, using natural grassland as a control (CK) adding three treatments: inorganic (IN), organic (ON) mixed treatment (MN, with 4:6 ratio to N). Our study assessed effects these properties crucial for cycling. findings indicate that enhance mineral content, ON leading highest increases nitrate ammonium content 92.44% 35.6%, respectively, compared CK. Both IN treatments boosted reductase urease ( p < 0.05), while MN decreased activity, showing greatest sensitivity activity changes. Soil pH slightly addition, but nitrite remained relatively unchanged (0.372–0.385 mg g −1 ). Correlation analysis revealed are regulators saline‐alkaline These results suggest should be considered nutrient models, addition potentially enhancing conversion mitigating limitations ecosystems.

Abstract Global agriculture is the largest anthropogenic source for nitrous oxide (N 2 O) emissions. During crop rotations, periods with arable soils without crops, thereafter called “bare soils” are often impossible to avoid after harvested, prior sowing of next crop. However, such underrepresented in studies focussing on N O Here, we present continuous, high-temporal-resolution fluxes during bare soil four major using eddy-covariance technique at two sites Switzerland. Overall, were net sources as well carbon dioxide (CO ) and methane (CH 4 ). Daily average sums emissions varied between 10 ± 38 5 g O-N ha −1 d respective rapeseed, winter wheat, pea, maize harvests. While CO contributed 86–96% total GHG budgets, accounted 2% but 10–12% maize. In contrast, CH negligible (< 2%). increased all cropland increasing water-filled pore space, particularly high temperatures. Thus, our study emphasizes significance avoiding mitigate from croplands.
