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

Abstract

There are increasing demands to increase the productivity of crops grown in unfavourable soil conditions. The objective 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 (mineral fertilizer activator, Olmix Group) on soil in terms of the yields of spring and winter wheat and winter rape. Numerous soil characteristics 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 structural coefficient. The biostimulants had a positive effect on the yields of crops.
