Panasenko E. Influence of agroameliorative measures on renewal of oil contaminated chernozem soil properties and fertility

Object - soils processes in oil polluted soils and influencing of agroameliorative measures for them. Purpose - acceleration of soils fertility renewal of polluted by an oil and products of its processing by simple, cheap and effective measures. Methods - field and laboratory research, methods of mathematical statistics. Theoretical results - it is shown that at the increase of soil structure density, the quantity of the adsorbed oil increases by the increase of moisture content influences on this process which diminishes maintenance of oil, but multiplies the depth of its penetration. The system of agroameliorative measures for acceleration of polluted by an oil chernozems fertility renewal, which consists in realization of simple and effective measures as top hoeing of soil , bringing of mineral fertilizers, straw, zeolite is developed and offered. Practical results - the optimum doses of soil improvers as for mineral fertilizers N1000P360K360, straw - 2 t/he, zeolite - 5 t/he are determined. A maximal harvest is got at the bringing of nitric fertilizers optimum dose 600 kg of active substance on a hectare in the first year after contamination and 400 kg of active substance on a hectare in the next year. This system of agroameliorative measures is recommended for enterprises, which are engaged in output of oil and gas and processing of oil, and also for the proprietors of lands, which related to oil and gas industry. Novelty - the complex studying of conduct and oil influencing on chernozems fertility as a result of which regularities of physical oil evaporation are set depending on a temperature condition, granulometric composition of soil and level of contamination are first conducted. Regularities are set in the dynamics of mobile Р2О5, К2О, nitrate and ammonium nitrogen maintenance changes under act of contamination by products of oil processing (petrol, kerosene, diesel fuel, and fuel oil). It is proved that speed of oil pollution soil fertility renewal depends on its maintenance. Degree of application - the researches results are represented in the standard of state Committee of natural resources of Ukraine 73.1-41-10.01:2004 "Environment protection. Estimation of soils contamination and determination of agricultural production losses as a result of worsening of lots lands quality during building of gases and oils wells", and also in technology of biological recultivation of oil polluted soils on state enterprises the "Neardnipers main oil pipelines". The field is an agricultural production, environment protection.
