Calibration of stem heat balance sensors upon a study of water balance of the hop plantation
Original language description
Evapotranspiration of the Czech hop cultivar Agnus plantation was investigated during three consecutive growing seasons. We measured two components of the water balance: total eva-potranspiration and transpiration of the bines (using the stem heat balance sensors type EMS SF62). Actual evapotranspiration peaked when the crop was fully developed, at 80-90 % of the potential evapotranspiration. To ensure the correctness of the sap flow measurements, calibration of the sap flow sensors was performed. Justbefore the harvest, total of 18 bines were removed from the plants and their water uptake was measures volumetrically. Acuracy of the sap flow measurement was ?3 % when compared against potometry.
