Short CommunicationSoil moisture controls on temperature sensitivity of soil organic carbon decomposition for a mesic grassland
Research highlights
► For soils collected from shallow, xeric uplands in a tallgrass prairie, temperature sensitivity was greatest at intermediate soil moisture. ► For soils collected from deeper, mesic lowlands, temperature sensitivity increased with increasing soil moisture. ► The magnitude of the soil moisture effect is large enough to alter soil C budgets and should be considered explicitly when predicting ecosystem responses to global change scenarios.

2023, Science of the Total EnvironmentCitation Excerpt :On the other hand, in PTR/CTW, the puddled soil conditions in previous rice crop creates a sub-surface hard pan which hinders root growth, restricts nutrient and water uptake and also causes lodging in next season wheat crop resulting in poor performance of growth and yield parameters and thereby lower crop yields (Jat et al., 2018a). Frequently applied irrigation water in mini-sprinkler and drip irrigation systems in residue mulched plots ensured better soil hydro-thermal regimes which might have beneficially influenced the organic matter decomposition and nutrients supply (Craine and Gelderman, 2011; Qi et al., 2016; Rathore et al., 2017). Furthermore, these improved micro-climatic conditions might have improved crop physiology like higher chlorophyll content of flag leaves which delayed plants senescence, accumulated more dry matter, and induced higher N uptake (Li et al., 2018).
