Goal. Study of peculiarities of growing pine stands and prospects of their use in agroforestry of Zhytomyr Polissia on the example of agricultural lands of Malyn Vocational College. Methods. Field, laboratory, analytical, statistical. Results. On sod-podzolic sandy soils of Zhytomyr Polissia pine seedlings after three years of cultivation were 55.7 ± 3.43 cm in height. The maximum increase in height was observed during the third year of cultivation of the plantation, when at the beginning of the growing season with herbicide Targon Plus the impact of cereal vegetation reduced to a minimum, resulting in improved seedling growth conditions. The high preservation of pine plants and their intensive growth allow us to make optimistic forecasts about the feasibility of growing them as a forest component of agricultural landscapes, especially given the presence of biotically stable 15-year-old pine plantations created by similar agricultural techniques. They were laid at an initial density of 7.1 thousand seedlings per 1 ha, and later thinned to 2982 and 1691 plants/ha, respectively. With almost the same productivity indicators, higher tree height (by 17.0%) and larger average diameter (by 23.8%) allow thinner plantations to have a more positive impact on adjacent agricultural lands, grow more intensively and have higher productivity in the future. This indicates the expediency of pine plantations in the region of research as a forestry component of agrolandscapes a density at the age of 15 years of about 1700 trees per 1 ha.

Black poplar (Populus nigra L.) is fast-growing species, demanding in terms of light and soil and very sensitive to weeds, especially in the first vegetation. Therefore, developing effective, environmentally friendly weed control measures is an urgent task for herbologists. There is an inverse relationship between the amount of weed mass and the productivity of black poplar; the lowest height, biomass yield and energy yield (87.1 cm, 0.41 t/ha and 8.06 GJ/ha, respectively) were found in the control treatment with the highest weed mass accumulation (3062 g/m 2). The practice of mechanical weed control influenced the accumulation of weed mass in the black poplar plantations. Three consecutive cultivations of interrow space and three consecutive harrowing sessions at an interval of 14 days reduced weed mass 2.7 times. Soil mulching with sawdust almost completely destroyed the weeds in the experimental plots.

The purpose. To determine the level of potential weediness of plowlands in the main soilclimatic zones of the country. Methods. Field and laboratory-sampling of soil on fields of Kyiv,
