αThe article presents the results of research on the effectiveness of the use of crops of Silphium Perfoliatum L. for phytoremediation of soils in oil-contaminated areas. Silphium Perfoliatum L. is characterized by unique opportunities for productivity and longevity, can be cultivated in one...

The research was conducted on the territory of Nadvirna oil and gas district of South-Hvizdetsky oil field of Ivano-Frankivsk region during 2016-2020. The production activity at the research site was stopped 45 years ago. Energy crops the Miscanthus (Miscanthus giganteus) and switchgrass (Panicum...

The article shows the possibility of using modern methods of artificial intelligence to calculate the yield of biomass of crops according to the given set input data (fertilizer doses, agrochemical parameters of the soil, productivity). The study reflects the results of testing a model of a...

Much of Ukraine’s soil has been and is still being degraded by military operations. Its revival will need a lot of organic matter, much of which can be provided by municipal sewage sludge. Any associated environmental risks may be minimised by applying the sludge to energy crops, in particular, Miscanthus x giganteus. The introduction of municipal sewage sludge at the rate of 20-40t/ha, or composted with straw, increases the content of total and mobile forms of heavy metals in the soil. But, the resulting concentrations of heavy metals remain well within permissible limits. The integral indicator of soil cover pollution for applications of various kinds of fertiliser applied at a rate equivalent to N₉₀P₉₀K₉₀ fluctuates within insignificant limits (20–23) with a tendency to increase in treatments with the highest rate of application of sewage sludge.

α The application of fertilizers based on sewage sludge significantly affects the formation of the nitrogen fund of sod-podzolic soil, as well as changes in the content of mobile compounds of phosphorus and potassium exchange. The application of such fertilizer under Jerusalem artichoke has a...
