Abstract: Nanotechnology products are able to ensure the cost-effective development of agricultural production, including obtaining high yields of good quality products. One of the products of nanotechnology is environmentally friendly metal nanoparticles. When using metal nanoparticles (NPs) in crop production and forestry, it is necessary to study the effect of these preparations on both the growth and development of plants and seedlings, and on the soil. Soil, unlike other components of the natural environment, not only accumulates substances entering it, but also acts as a natural buffer controlling the transport of chemical elements and compounds into the atmosphere, hydrosphere and living matter. Unlike plant seeds, pine seedlings at the planting stage have a monaxonic nonbranching shoot, juvenile needles, and a root-stem type root system. Therefore, the increased safety and growth of seedlings was due to additional energy in the form of iron nanoparticles, stimulating the activity of enzymes and phytohormones, and, consequently, the movement of nutrients and water. The use of iron nanoparticles contributed to an increase in needle packing of the Scots pine from the first years of observation and the length of the needles. Iron nanoparticles activate synthetic processes and the plant removes a greater amount of NPK from the soil, so there are better conditions for mineral nutrition, which may subsequently affect the quality of wood.
