Different management strategies exert distinct influences on
microclimate of soil-atmosphere system in tea fields
Abstract
Agricultural management strategies are crucial in regulating the
soil-atmosphere interaction. The crop landscape is influenced by farmers
through different field practices, and further impacts the variations of
soil temperature, soil moisture, and field microclimate. To examine how
different management strategies affect the soil properties and the
aforementioned interaction, two observation systems were installed in an
organic-certified (ORG) tea field and a conventional (CONV) tea field in
northern Taiwan. The results show that the variation of canopy
temperature was more significant in CONV while the difference in soil
diurnal temperature range was minor. However, the daily loss rate of
soil water content in ORG was two times faster than that in CONV (0.93%
d−1 vs. 0.46% d−1). These findings suggest that the appropriate
management strategies could assist farmers in adapting to environmental
fluctuations and provide quantitative references for assessing soil
characteristics under different agricultural applications and climatic
conditions.
