Objective

Intense growth of the population calls for non-stop increase of production of various agricultural crops, while arable lands are decreasing swiftly because of progressing urbanization and intensification of industry. Efficient way to resolve this problem, that is, provision of the population with foodstuff, is inculcation of intense advanced technologies in agriculture, such as application of nitrogen-containing chemical fertilizers in increased dose.

According to available data, annually more than 200 million ton nitrogenous fertilizers are introduced into soil in the whole world. Because of their very good water solubility, major part of fertilizers (up to 100 million ton) is lost, as a result of evaporation and washing off, which results tremendous economic losses. At the same time environment (water reservoirs, rivers, ground waters, ponds, lakes, seas, wells and others) is globally polluted. Part of nitrogenous fertilizers is evaporated and reaching high strata of atmosphere, destructs ozone layer, which results in many heavy diseases in the world.

Regular application of such fertilizers makes unfavorable impact on soil and environment. They, can result in imbalance in components assimilated by plants, while accumulation of nitrate in great quantity makes negative effect on human and animal health. Increase of costs for non-renewable energy sources resulted in increase of prices of fertilizers and food.

Among all type nitrogenous fertilizers used in practice, unconditional leaders are nitrates –salts of nitric acid, among which the most widely used and manufactured is ammonium nitre, but it is dissolved in water better than others and is easily washed off to soil.

Therefore, one of the main tasks of is synthesis of the polymer (polymeric) nitre which will release slowly nitrogen because of degradation effect of soil microorganisms. The present project are offering to use receptor - nitrogen-containing substance, possessing reactive centers, its structuring, for further obtaining of polymer nitre. In this way, nitrogen content in the system can be increased by 25 – 30 in polymer nitre.. Nitrogen concentration can be regulated by alteration of molar ratio of initial acceptor and nitrogen-containing other reactive component.

We expect that the offered polymer fertilizer of new generation – polymer nitre, that is degradable in soil, will be significantly improved compared to monomer nitrate, since at the impact of adapted microorganisms it will undergo slow, gradual degradation to water soluble nitrogen-containing fragments accessible for plants and will be more efficient, which will contribute to economy of 50% nitrogenous fertilizers, compared with the currently used quantity.
