In this study, we evaluated the short-term impact of crop stover management and the interaction between crop stover and irrigation method on SOC change in a continuous maize (Zea mays L.) system in Spain. Four years after the beginning of the experiment, total SOC and C fractions (particulate organic matter carbon, POM-C; and mineral- associated organic matter carbon, Min-C) contents, SOC stocks and SOC stock changes were measured in four different soil layers (0− 5, 5− 10, 10− 25 and 25− 50 cm) in an experiment with two irrigation methods (sprinkler and flood) and three stover management systems (conventional tillage with all the stover incorporated, CT; no- tillage maintaining the stover, NTr; and no-tillage removing the stover, NT). Stover management resulted in significant differences in SOC and POM-C but not in Min-C. In particular, NT reduced SOC and POM-C contents compared with CT and NTr (about 10 and 60 %, respectively). After 4 years, SOC change was not affected by the interaction between stover management and irrigation. Concurrently, both CT and NT showed SOC losses, reaching 0.11 and 1.22 Mg ha− 1 yr− 1 in CT and NT, respectively. However, NTr showed SOC gains at a rate of 0.09 Mg ha− 1 yr− 1. Consequently, the removal of crop stover has been demonstrated as a detrimental strategy to store SOC in the short-term in irrigated continuous maize systems. info:eu-repo/grantAgreement/ES/AEI/AGL2017-84529-C3-1-R info:eu-repo/grantAgreement/ES/MINECO/AGL2013-49062-C4-4-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 7.366 2021 SOIL SCIENCE 5 / 39 = 0.128 2021 Q1 T1 1.806 2021 Earth-Surface Processes 2021 Q1 Agronomy and Crop Science 2021 Q1 10.0 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Franco-Luesma, Samuel Lafuente, Victoria Sen, Pablo Usón, Asun Universidad de Zaragoza (orcid)0000-0002-0139-0843 Cantero-Martínez, Carlos Arrúe, José Luis 5011 705 Universidad de Zaragoza Dpto.
