METHOD FOR SPIKED CEREALS POSTHARVEST DISK STUBBLING DEPTH VARIABILITY ESTIMATION Russian patent published in 2016 - IPC G01N33/24 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly to methods of determining spiked cereals disk stubbling depth quality indicators. Spiked cereals postharvest disk stubbling depth variability estimation method provides for, what with help of cord marked along combined harvester trace axis of symmetry, laid from nontreated to treated slot and along parallel line, equidistant from combined harvester trace in adjacent passes, broken layer depth measurements are carried out. Then average depth values by measurements lines are calculated and average depth of dressing reduction degree are determined by them, then by dependence U=14.472 e^0.0167x stubbling depth variation factor across field is determined.

EFFECT: method enables increase in spiked cereals postharvest disk stubbling depth variability estimation accuracy.
