Tóm tắt

Soil classification is essential in mapping soils, land evaluation, and sustainable soil usage. Nowadays, along with the Industrial Revolution 4.0, there is an interest in the development and promotion of information technology in classifying soils. This paper aims to introduce the software supporting soil classification of Vietnam (ICSM) according to the semi-quantitative soil classification system of Vietnam and to apply it to classify the BTGD-06 soil profile as a pilot example. It consists of three main components: (1) Menu and toolbars, (2) Tabs to input data, and (3) suggesting and identifying blocks. It was also applied successfully to classify five soil profiles in Vietnam and illustrated by classifying the soil profile BTGD-06. The results of the trial classification are the same as those published in the Journal of Vietnam soil science about the diagnostic horizons, soil group, soil type, soil subtype, and soil variety. The algorithms used in developing the software can be used to write other quantitative soil classification software worldwide.
