Laboratory Calibration Of The Spectrum Field Scout Tdr 300, W. Dyer, D. Bremer, P. Rossini, M. Stone, A. Patrignani

Kansas Agricultural Experiment Station Research Reports

Soil moisture sensors (SMSs) are a useful tool that aid in data-driven water management decisions. However, default factory calibrations can be inaccurate and soil-specific calibrations are often required to obtain higher accuracy in the determination of soil water storage and plant available water. In this study, we conducted a lab calibration for the Field Scout TDR 300, which is a popular SMS used in the turfgrass industry. Five soils of different soil textural classes were packed in containers with known soil moisture for the laboratory calibration. The logarithmic model best fit the data for the course- and fine-textured soils, with …

Calibration Of Boom Sprays, J R. Peirce

Journal of the Department of Agriculture, Western Australia, Series 4

Boom sprays have become increasingly common on Western Australian farms, allowing farmers to take advantage of modern herbicided.

Most boom sprays used on farms have 50 cm nozzle spacings and require calibrating regularily to ensure accurate herbicide application.

By following these steps, the boom will deliver accurate amounts of herbicide.
