The definition of the concept of «communicative personality» is substantiated. It means the subject of speech, who is able to express his thoughts freely and competently, who knows the language norms, expressive means and stylistic resources of the literary language, who is able to create oral and written texts of different genres, to receive and analyze information from different sources, possessing communication technologies and the ability to use them effectively in professional and other communication situations. The definition of the concept of «professional ideal» is formulated. It implies the image of a highly qualified professional, which has developed in the mind of a student of a higher educational institution. The necessity of creating psychological and pedagogical conditions for the formation of professional and communicative competence of students of an agricultural university in the disciplines of the speech cycle has been proved. Among them are the following: the formation of the professional ideal of students as a personal, internal motivation for learning; a communicative-cognitive approach to the formation of a student's communicative personality; gradual formation of a communicative personality in the learning process.

The regularities of the accumulation and distribution of metals (Zn and Cd) in various parts of wild herbaceous plants and the agricultural crop of the impact zone in Rostov region (Russia) was considered. A large accumulation of elements in wild herbaceous plants of the Asteraceae family was noted compared with Triticum aestivum. The pollution of Triticum aestivum by Cd was observed. Wild herbaceous plants of the Asteraceae family were contaminated mostly with Zn. It was found that Artemisia austriaca and Ambrosia artemisiifolia accumulated Zn and Cd in the aboveground part. Achillea nobilis accumulated Cd mainly in the root system. Closer location monitoring plots to the source of anthropogenic load and the location of the northwest winds prevailing in the region were main influencing factors leading to higher pollution.

The effect of various doses of diatomite introduced into soil artificially contaminated by benzo[a]pyrene was analyzed. The negative effect of benzo[a]pyrene on the growth of barley (Hordeum sativum distichum) seedlings and reduction of toxic effect of polyarene on plants after implementation of diatomite as a sorbent into contaminated soil are shown. A significant increase (by 2–3 times) of the plant growth in contaminated soil with the addition of diatomite has been revealed. The introduction of 2.5% diatomite into contaminated soil had the significant positive effect on barley seedlings.

The legitimacy of identifying linguomental categories as a set of concepts and their verbalizing signs (linguistic units), which are characterized by homogeneity based on the commonality of a certain feature, fixing the results of human cognitive activity, has been proven. The identification of the linguomental category of relevance is substantiated, accumulating concepts (mental signs) that are socially significant at a particular historical stage, which are represented by linguistic units that form an active vocabulary of native speakers. The definition of actualema – a mental sign that objectifies the category of relevance is formulated, its features are characterized, including chronological determinism, sociocultural marking, semantic versatility, dynamism. The composition of the actual vocabulary of the modern Russian language is considered. It includes: lexical and semantic neologisms of the last decades, external borrowings, internal borrowing, updated vocabulary, nominally reoriented vocabulary. On the example of the study of the actual concept of charity and the linguistic units verbalizing it, the effectiveness of the linguo-conceptual analysis of the actualeme is shown, which revealed an obvious connection between actual concepts, language and the realities of the outside world, which is relevant both for the scientific sphere and for educational activities.
