Abstract: 
Grassland re-seeding or land-use change requires ploughing, which may enhance carbon dioxide (CO(2)) emissions from soil. This study observed the short to intermediate-term (37 days) effects of ploughing on CO(2) emissions from poorly drained grassland using automated soil respiration chambers. Immediately after ploughing, a brief peak in CO(2) emissions from soil occurred with a maximum observed flux of 6.91 g CO(2) m(-2) h(-1). Contradictory to other reported results, ecosystem respiration after ploughing was lower on the ploughed than on the grass site. After including estimates of photosynthesis in the analysis, ploughing led to significantly higher net CO(2) emissions than from grassland. The main mechanism of C loss during ploughing was most likely due to a reduction in gross primary production rather than enhanced soil respiration. (C) 2011 Elsevier B.V. All rights reserved.
