Determination of the influence of biostimulants on soil properties and field crop yields

. There are increasing demands to increase the pro-ductivity of crops grown in unfavourable soil conditions. The ob-jective of this study was to evaluate the potential of biostimulants to improve soil properties and crop yields. A field experiment was conducted to assess the impact of Neosol (a soil activator), biostimulant Explorer (a rhizosphere activator) and AKEO (min - eral fertilizer activator, Olmix Group) on soil in terms of the yields of spring and winter wheat and winter rape. Numerous soil char - acteristics related to soil structure were evaluated at the 0-20 and 20-40 cm depth ranges e.g. bulk density, soil porosity, structural coefficient. The results show that the application of biostimulants has a positive effect on soil bulk density, porosity and the struc - tural coefficient. The biostimulants had a positive effect on the yields of crops.
