En septembre, des mesures d\u2019activ\u00e9s biologique des sols d\u2019OPTMix ont \u00e9t\u00e9 r\u00e9alis\u00e9es par l\u2019\u00e9quipe d\u2019ESE de Paris-Sud Orsay avec le soutien d\u2019agents INRAE Nogent-sur-Vernisson.<\/p>\n

Dans le cadre de l\u2019\u00e9tude de la d\u00e9finition du stock de carbone des sols et de sa stabilit\u00e9, nous \u00e9tudions l\u2019effet de la sylviculture sur les sorties de CO2 des sols. Pour cela, nous r\u00e9alisons des mesures de respiration du sol dans les parcelles (sans cl\u00f4ture) aux trois densit\u00e9s (faible, moyenne, forte) dans tous les peuplements. Cette campagne s\u2019ajoute \u00e0 celles r\u00e9alis\u00e9es en 2018 et 2019. Elle sera de plus compl\u00e9t\u00e9e par des mesures de laboratoire sur des \u00e9chantillons de sol pour d\u00e9terminer la sensibilit\u00e9 de la respiration du sol \u00e0 l\u2019augmentation des temp\u00e9ratures (incubations en conditions contr\u00f4l\u00e9es \u00e0 diff\u00e9rentes temp\u00e9ratures pour simuler le climat futur, avec mesure du CO2 \u00e9mis).<\/p>\n
