The objective of this study was to investigate and model seasonal variation of soil CO_2 emissions from an apple orchard field (Malus domestica L. 'Starkrimson'). Soil CO_2 emissions from an apple orchard managed with common practices were measured weekly over a 3-year period (May 2008 to May 2011) from both under the crowns of trees (CO_2-UC) and between rows (CO_2-BR) using a soda lime technique and were modeled using available environmental data. The study area is located …
