Abstract
<p>Management strategies in agricultural landscape plays a vital role to regulate soil moisture-atmosphere interaction. How farmer manage the canopy shading of their crop is a key factor to participate the interaction. The components that can be affected include soil temperature, soil water content and evapotranspiration. Soil temperature and water content sensors had been set in two neighboring tea fields in northern Taiwan that have their own management strategies by farmers, and eddy-covariance equipment also measure the evapotranspiration. Long-term ensemble average result showed that soil water content decreasing rate in organic-certified tea field is -1.23% Day<sup>-1</sup>, and conventional field is -0.76% Day<sup>-1</sup>. Among the decreasing rate has an obvious turn in four to five days after rainfall event. In addition, Diurnal difference of soil temperature between two fields in summer can reach 1.86 °C. Although organic tea field has milder diurnal soil temperature difference, but the dynamics of soil water content is higher than conventional field.</p>
