Estimating sap flux densities in date palm trees using the heat dissipation method and weighing lysimeters.
In a world of diminishing water reservoirs and a rising demand for food, the practice and development of water stress indicators and sensors are in rapid progress. The heat dissipation method, originally established by Granier, is herein applied and modified to enable sap flow measurements in date palm trees in the southern Arava desert of Israel. A long and tough sensor was constructed to with...
متن کاملMini-lysimeters to monitor transpiration and control drought stress: system design and unique applications
Methods for the precise control of drought stress have been a holy grail of plant biology research. Here we describe a five-container growth chamber system and a 16-container greenhouse system, each of which uses load cells to monitor and control the mass of a soil/plant system. The calibration and signal conditioning necessary to quantify transpiration over 10 minute intervals is described. Ev...
متن کاملA Data Acquisition System Based on Outlier Detection Method for Weighing Lysimeters
The weighing lysimeters provide scientist the basic information for research related to the evapotranspiration, high quality of the collected data from lysimeters is of great significance. However there are many factors that can affect the measurement accuracy of the weighing lysimeter. In this paper, a data acquisition system was developed to collect the data from 24 weighing lysimeters. The c...
متن کاملConstruction and Performance of Large Soil Core Lysimeters
This may cause an unrealistic soil moisture regime and may effect crop growth. A method was developed to obtain large undisturbed soil cores To more closely represent an uninterrupted soil coland instrument those cores to collect vadose zone leachate data under agricultural field conditions. Twenty undisturbed soil core lysimeters umn at the point of leachate collection, a vacuum extracwere con...
متن کاملThe use of high-resolution weighing lysimeters to improve estimates of soil evaporation in drip-irrigated olive orchards
Soil surface resistance increase quickly during the first three days after irrigation or rain event. By explicitly incorporating surface resistance in simple equations, daily total evaporation estimation of a drip-irrigated olive grove was significantly improved. This increase in soil surface resistance could explain why observed cumulative soil evaporation is higher in locations with lower irr...
