A pot experiment with tomatoes was carried out on Alluvial-Meadow soil. The influence of increasing concentrations of enriched nutrient vermiculite on biometric characteristics and content of nutrients in tomato plants were tested. It was found a positive impact from the application of the tested product on the growth and development of tomato. With increasing participation rates of vermiculite in the experiment and increase the value of the included parameters: plant height, number of leaves, stem diameter, number of blooms, stem mass, leaf mass, mass fruit. The measured content of total N, P, Mg, Fe, Cu, Zn, Mn in vegetative mass of tomatoes increased by increasing the percentage of vermiculite in the experiment.
