Soil biostimulant comparison to NPK fertilization in relationship to improvement of rhizosphere function

Original language description

Unequal distribution of annual precipitation is negative trend of last year’s influencing primary agricultural field production. One of the natural possibility for elimination of this gesture is to increase patience to the actual conditions and functionality of root system of the plants. Among possible abilities of field crops protection to abiotic stresses during vegetation period belongs strengthening of their natural tolerance. Present situation of soil degradation does not allow to plants sufficiently deploy rooting system so they are not able naturally tolerate to these abiotic stresses, as well as it decreases the efficiency and utilization of mineral nutrients applied in mineral fertilizers. The study is aimed to analyze the advancement possibilities of biological soil systems due to biostimulation of plant root system by soil biostimulants in comparison to common fertilization by NPK type mineral fertilizer. There were prepared 5 variants in experiment: control (without fertilization), NPK fertilization and three variants with soil biostimulant - rhizosfere activator Explorer 20, which sustain microbiological activity close to root system and mineralization processes in the soil. There were observed the changes of oxidable carbon (Cox) content, soil organic matter (SOM) content, C/N ratio and nutrient content, especially N-forms. There was an increase in plant biomass production (on average more than 15% compared to control variant) and an increase in SOM content (on average more than 10% compared to control variant and NPK variant). Due to the improved rooting system increased the content of soil organic matter. Increasing content of SOM had a positive effect on Cox values and also on the release of accessible nutrients into the soil solution. This result was obtained primary due to increased soil biological activity and improved deployment of roots and their symbiotic rhizosphere function. The study confirms that there is an alternative to conventional plant nutrition that positively affects plant growth and soil quality.
