Estimation of Crop Coefficients of a High-Density Hazelnut Orchard Using Traditional Methods vs. UAV-Derived Thermal and Spectral Indices

Agriculture
Evapotranspiration and crop coefficients are key variables for designing efficient irrigation strategies in tree crops, yet standard tabulated coefficients derived for mature, fully covering orchards often fail to represent the water use of young, high ...

Determination Of Crop Coefficients Of Maize For The Estimation Of Crop Water Use

, 2018
The crop coefficients (kc) of maize were determined for the growing season of month June to mid September. A hydraulic weighing lysimeter in National Centre for Agricultural Mechanization (NCAM) was used to determine the crop evapotranspiration (ETcrop) for maize while meteorological data from the weather station at NCAM was used to compute reference ...

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Using weighing lysimeters to develop evapotranspiration crop coefficients [PDF]

, 1991
Weighing lysimeters provide an accurate means of measuring evapotranspiration (ET), the evaporative loss of water from growing crops. Two weighing lysimeters were installed at a research site near Kimberly, ID, and have been used during the past 20 years
