Hydrology and Water Resources
Agricultural production is based on responding issues related to climate change in the coming years. Frequent drought seasons lead to a decline in yield production, and negative hydrological balance is expected in the future, which will also affect water consumption for agriculture [1]. Based on sap flow measurements, it is possible to optimize irrigation. For our experiment was used the grape vines in Nitra region, on which we installed Dynagage Sap Flow Sensors with the Flow 32-1K Sap flow system, which measure the sap flow and thus water consumption of plants. These energy balance sensors measure the amount of heat carried by the sap, which is converted into real-time sap flow. The measurements were carried out during the summer months, when the drought stress can be shown. The measured values were compared with soil moisture and temperature. The results show the relationship between sap flow and soil moisture, which can optimize water supply in real time, but long-term measurements are needed.
