FIELD: agriculture.
SUBSTANCE: method involves taking cores of wood and separation part of it for the ultrasound measurements. The ultrasound measurements are carried out on the entire length of the working core by consecutive cutting of annual rings, starting from the end of the working core on the tree trunk periphery. Then the values of the ultrasound speed are ranged on the time scale beginning with the period of tree growth and further on year rings counting from the core to the periphery of the tree trunk. After that the ultrasound speed dynamic statistical regularities during tree growth and development are revealed that characterises the quality of wood and predict the dynamics of the ultrasound speed.
EFFECT: quality of integrated environmental testing of adult wood increases.
