The article describes the main stages of life and formation of an outstanding scientist in the field of agro-chemical science professor Yuri I. Yermokhin. His development as a scientist and educational specialist took place at Omsk State Agrarian University. Yuri Ivanovich developed physiological and biochemical prospects in modern agricultural chemistry, which resulted in the creation of an integration system of soil-plant operative diagnosis of food crops («ISPROD»). Nowadays Yuri Ivanovich is focused on the study of ecological and varietal agrochemistry in the system «soil - plant - fertilize - bioclimatic potential». Graduates of the scientific school, the head of which has been the professor Yuri I. Yermokhin over 50 years, now successfully work in Russia and abroad and many of them are teachers at OmSAU named after P.A. Stolypin. Currently, graduates and doctoral students under the direction of Yuri Ivanovich make research and development of macro- and micro-elements in the soil and plants depending on the calculated doses and correlation of fertilizers for crops, fodder and medicinal crops.
