МЕТОД ИЗМЕНЯЮЩЕГОСЯ ГЕОМЕТРИЧЕСКОГО КОЭФФИЦИЕНТА ДЛЯ ОПРЕДЕЛЕНИЯ ЭЛЕКТРОПРОВОДНОСТИ/ЭЛЕКТРОСОПРОТИВЛЕНИЯ ПОЧВ

г. Витебск, Республика Беларусь

Представлен новый метод калибровки и обработки данных по электросопротивлению почв, полученных с использованием квадратной установки и неизолированных электродов. Метод основан на впервые выявленной линейной зависимости между глубиной погружения электродов в калибровочный раствор 0,001 М калия хлорида и геометрическим коэффициентом установки. Аппроксимация зависимости с помощью линейной регрессии позволяет оперативно рассчитывать актуальные значения геометрического коэффициента для различных субстратов, включая почву и водные экстракты. Разработано устройство для контролируемого заглубления электродов, обеспечивающее воспроизводимость измерений и снижение экспериментальных погрешностей. Предложенный подход открывает новые перспективы для стандартизации методики в почвенных и агрохимических исследованиях.

Такие измерения электросопротивления могут служить индикатором специфических условий местообитаний, способствующих формированию уникальных фитохимических профилей и адаптивных стратегий лекарственных растений.

SUMMARY

METHOD OF VARIABLE GEOMETRY FACTOR IN SOIL ELECTRICAL CONDUCTIVITY/RESISTIVITY DETERMINATION

A novel method for calibrating and processing soil electrical resistivity data has been developed using a square electrode configuration with non-insulated (bare) electrodes. The method is based on a newly identified linear relationship between electrode immersion depth in a 0.001 M potassium chloride (KCl) calibration solution and the geometric factor of the configuration. This dependence approximation using linear regression allows to calculate topical data of the geometric factor for various substrates including soils and aqueous extracts. A device for controlled electrode immersion providing measurements reproducibility and reduction of experimental errors has been designed. The proposed approach opens up new prospects for standardizing the methodology in soil and agrochemical research.

Such measurements of electrical resistivity can serve as an indicator of specific habitat conditions contributing to the formation of unique phytochemical profiles and adaptive strategies of medicinal plants.

Keywords: soil electrical resistivity, geometric factor, square electrode configuration, bare electrodes, linear regression, calibration solution, potassium chloride (KCl), controlled immersion, soil extract, measurement methodology.
