Étude bioclimatique d'un verger-maraîcher : quelles influences du contexte paysager et de la gestion du sol sur le microclimat pour la fertilité du sol ?

Abstract : Soil microclimate, particularly temperature and humidity, greatly influence market gardening’s production. Spatial measures conducted from 8 of april to 7 of july were used to describe the microclimate of an agroforestry system combining vegetables and fruits production. Distance, orientation to the trees and trees density was also characterised. With a statistical approach, we showed that measured mean temperatures were inferior in the agroforestry system compared to those observed in a system with less trees. Soil temperature range is buffered by trees’ presence, and high soil temperature extremes are lowered. These effects diminish while distance to the trees increase. Mulching and no-tillage buffer temperature daily variations and lower mean surface temperatures. Conditions offered by agroforestry and mulched systems also are favorable to pedofauna development, allowing the soil to become functional again.
