Intensive agricultural production alters the natural cycle of nutrients in the soil, very often leading to a reduction in organic matter and soil degradation. The use of biоfertilizers would solve these problems and make the ecosystem healthier. The biofertilizers used in the study have a positive effect on Triticum spelta L. growth. The results of the treated variants with Litovit, Tryven, Baikal EM and Amalgerol, show a higher height of the plants in the stem elongation phase compared to the control, by 20%, 15%, 12% and 10.8%, respectively. At full ripeness, the general stimulating effect of the applied foliar biofertilizers on the height, better nutrition and growth of the plants is taken into account. Greater soil microbial activity in the studied biofertilizers was observed on the 14th day after treatment. Higher values are reported for all variants of combined fertilization (foliar fertilization on basic fertilization with Agriorgan pellet) compared to unfertilized control and self-fertilization with Agriorgan pellet, which is statistically proven.
