Alley-cropping agroforestry enhances carbon sequestration compared to open cropland and open grassland, and improves soil biological habitat and erosion resistance relative to open cropland, based on measured ecosystem functions at five sites in Germ

The O2:CO2 exchange ratio of plants is an only recently explored new plant trait and provides novel insights into the carbon cycle. Measurements of O2 fluxes at field sites are, however, scarce due to a number of technical challenges. This work prese

Agroforestry (AF) systems are recognized as a more sustainable agricultural practice compared to conventional agriculture due to its potential for increase carbon sequestration, among others. Short Rotation Alley Cropping (SRAC) is an AF practice in

In this study, we present the 23-years long dataset (2000-2022) provided by the flux tower site (DE-Hai) in the National Park Hainich, Thuringia, in Central Germany. Next to eddy-covariance flux measurements comprehensive datasets of meteorological a

While the eddy covariance (EC) technique is a well-established method for measuring water fluxes (i.e., evaporation or ’evapotranspiration’, ET), the measurement is susceptible to many uncertainties. One such issue is the potential underestimatio

Wind erosion is seen as one of the main risks for modern agriculture in dry and sandy regions. Shelterbelts and agroforestry systems are known for their ability to reduce wind speed and, consequently, wind erosion. The current study considers tempera

Measurements of the isotopic composition of water vapor (H2O v ) provide valuable insights into the hydrological cycle, whereas eddy covariance (EC) measurements are widely used to quantify biosphere-atmosphere exchange processes. Yet, the direct com
