Holm Voigt, Asia Khamzina, Bernd Diekkrüger, Inken Rabbel.  2017.  Quantifying stand water use through sapflux and groundwater measurements at a multi-species afforestation site in Uzbekistan, Central Asia.  Irrigated agriculture is the main economic activity in the lower Amudarya Basin of Uzbekistan characterized by arid, continental climate. The sector is threatened by precarious irrigation water supply and increasing soil salinity. Afforestation trials on degraded cropland with a shallow water table showed the potential to provide alternative agro-ecosystem services and rural income from the degraded land while requiring only little irrigation. To assist in afforestation planning, we assessed the stand water-use of three tree species, Elaeagnus angustifolia, Populus euphratica, and Ulmus pumila, using heat dissipation sensors during the growing season (March-October), 9 and 10 years after planting (2012 and 2013). Furthermore, the stand water use was quantified from observations of diurnal groundwater observations (for more details please see the respective poster submission). Previous dryland studies on tree stand water use suggest that stand water use ranges from 0.2 to 4.0 times the reference crop evapotranspiration (ETref) according to Penman-Monteith. The seasonal ETref was 868 and 854 mm in 2012 and 2013, respectively. Water use values derived from measurements of the field-calibrated heat dissipation sensors ranged from 0.01 to 0.37 of ETref (or 10-170 mm). Applying the original Granier function resulted in higher seasonal stand water use ranging from 0.02 to 0.66* ETref (or 15-552 mm). Analysis of the groundwater oscillations resulted in seasonal stand water use of 1.12‒4.9* ETref (or 942-4279 mm). Peak water use recorded with the sapflux probes occurred during the early and late season, whereas the groundwater measurements suggested peak water-use in the mid-season. Populus euphratica showed the highest water use among the species with either method. While estimates derived by sapflux measurements tend to underestimate stand water use, results calculated from groundwater oscillations might be overestimations. However, due to its generally high water use P. euphratica should be recommended cautiously for the dryland afforestation efforts. Further Information
Holm Voigt, Bernd Diekkrüger, Asia Khamzina, Inken Rabbel.  2017.  Stand water use assessed by diurnal groundwater oscillations – an alternative approach to sapflux quantification.  Tree water use is a major component of hydrological balances in forested watersheds. The frequently used heat-based sapflow measuring techniques is challenged by the necessity of upscaling the sapwood area based measurements to whole tree and stand levels. In agro-ecological systems with a shallow groundwater table, water uptake of trees leads to distinct diurnal fluctuations of the groundwater table. We developed a method to directly evaluate stand-level water use based on these fluctuations. The measurements were conducted at a mixed-species (Elaeagnus angustifolia, Populus euphratica, and Ulmus pumila) afforestation site in irrigated croplands of the lower Amu Darya Basin. Groundwater depth was monitored during the growing season (March-October) of 2012 and 2013 in the 9-10-year-old plantation of about 2.5ha. The soil water retention curve was derived from soil properties using the description of van Genuchten (1980). Assuming equilibrium soil moisture characteristics, the water uptake by trees per day was computed as the integral over the water retention curve from completely saturation to the soil suction equivalent of the difference between daily minimum and maximum groundwater depth. To account for lateral groundwater fluxes, the daily trend of the groundwater table (〖tGW〗_d) was assumed to be reflected by the difference between the daily minimum, average and maximum groundwater depth compared to the day before. To reflect the assumption that tree water uptake is primarily active during daytime, 〖tGW〗_d was related to the actual duration of sunshine. During the measurement period, the groundwater table fluctuated between 0.3 and 2.8 m below the soil surface with small daily magnitude during early and late season and high daily magnitudes during summer months. The average daily oscillation was 10.2 cm. The estimated seasonal water use ranged between 1618 and 4279 mm in 2012 and between 942 and 2502 mm for 2013, peaking in plots of P. euphratica.

Holm Voigt, Maximilian Weigand, Andreas Kemna, Bernd Diekkrüger.  2017.  Sensing sap flow by electrical self-potential measurements.  Sapflow represents a key process for understanding transpiration rates and water relations of plants. It is widely investigated by employing thermometric methods, which have been developed during the 1980’s and since then have undergone various improvements. However, these methods comprise several theoretic pitfalls and practical issues which lead to a huge variability in resulting sapflow estimates, especially when quantification is needed. We propose electrical self-potential (SP) measurements as a possible addition, or alternative, to established methods to gain information on sapflow in trees. To that end we performed two experiments to investigate the feasibility of the SP measurement approach: on freshly cut stem segments (experiment I), and on a living specimen of Picea abies at the Wüstebach field site (experiment II). For experiment I, freshly cut tree segments were subjected to a pressure head of ca. 0.45 bar to emulate water flow through the xylem. “Flow” and “non-flow” conditions periodically alternated in approx. 60 minute intervals. SP measurements were conducted using two non-polarizable electrodes located at the top and the bottom of the stem segment. The measurements show consistent behaviour during the three relevant phases: initiation of water flow, water flow, termination of water flow. For experiment II, we installed five non-polarizing electrodes along a vertical transect and additional four electrodes in a circumferential transect at approx. 2 m above the ground. The tree under investigation was also equipped with thermal sapflux sensors. Electric potentials were measured with reference to an electrode located 4 m northwest of the tree in the soil. The recorded signals followed the climatic patterns. Our results suggest that electrical self-potential measurements can be used to non-, or minimally, invasively infer information on sapflow in trees. Future work will address the optimization of the measurement methodology as well as the quantitative interpretation of the results. Further Information
