2026-08-05 Prolonged Dry Spells During the Reproductive Stage Significantly Suppress Ecosystem Carbon Fluxes in Maize Cropland doi:10.57760/sciencedb.44573 en Interannual variability in the NEE was primarily driven by prolonged dry spells during the reproductive stage. Maize cropland without straw return acted as a net C source when harvest removals were considered. We therefore recommend promoting straw return practices in the region to strengthen soil carbon sequestration capacity and enhance agroecosystem resilience to drought. And further research is needed to evaluate the role of straw return practices on the carbon budget in the area. drought; eddy covariance; karst ecosystem zhang lin luo weijun wang yanwei xing xuegang yang junming chen jia cheng anyun wang shijie PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset http://www.doi.org/10.3390/agriculture16151601 Science Data Bank
