Stages of professional formation and scientific researches of Professor Oleg Nagursky - higher education, scientific degrees and professional experience are described in the article. The main results of scientific researches and possibilities of their practical application are presented.
One of the major problems of pollution of soil environment, namely by components of mineral fertilizers due to their massive and continuous use in agriculture was analysed in the article. Possible ways of penetration of not absorbed mineral fertilizers deep into the soil as the main reason for getting fertilizers in the lower layers of the soil environment were investigated. A comparison of the impact of soil and climatic conditions on the rate of penetration of fertilizers deep into the soil was done.
Physico-chemical properties of specially modified forms of natural biopolymers – carboxymethyl cellulose and xanthan gum – were studied. The effectiveness and ability to film formation of water soluble polymeric compositions of these biopolymers, their influence on the growth and productivity of agricultural crops were examined. The effect of the biopolymers, mineral fertilizers and micronutrients content in the solution on its viscosity, as well as the dependence of the formed films thickness on the content of modified biopolymers and fertilizers were investigated.
