Alena Yuryevna Ozheredova, senior lecturer of the Department of Agrochemistry and Plant Physiology, defended for the degree of Candidate of Agricultural Sciences in the specialty 01.01.04 - Agrochemistry. Theme of the dissertation A. A. Ozheredova - "Determination of doses of mineral fertilizers to achieve the planned yield of winter wheat varieties on leached chernozem of the Stavropol Upland." The head is Doctor of Agricultural Sciences, Professor of the Department of Agrochemistry and Plant Physiology, Professor of the Russian Academy of Sciences Alexander Nikolaevich Esaulko.

For four years Alena Yuryevna was engaged in research on the subject of work, during which a positive effect of calculated doses of mineral fertilizers on the agrochemical parameters of leached chernozem was established, the planned yield level is 5.0, 7.5 and 10.0 t / ha and the quality of grain of winter varieties wheat. The mathematical and normative substantiation of the planned crop yield is presented depending on the content of macro- and microelements in soil and plants.The experimental data obtained make it possible to recommend modern varieties and estimated doses of mineral fertilizers to agricultural producers of the Stavropol Territory that contribute to the planned yield of 7.5 and 9.2 t / ha.
