Use of a colloidal solution of metal and metal oxide-containing nanoparticles as fertilizer for increasing soybean productivity

Abstract

Since the availability of micronutrients in agricultural soil are strongly depended on changes in soil characteristics, microfertilizers are one of the most effective means of influencing crop productivity and product quality. The use of nanoparticles of metals compensates for the loss of microelements, increases the stress tolerance of plants, both of which improve the quality of the final product. The aim of the research was to study the characteristics of a colloidal solution of metal nanoparticles (Mn, Cu, Zn, Ag, Fe) using X-ray diffraction to estimate the prospects of using them in agrotechnology. The objectives of the study included optimizing the method for treating plants and determining effective concentrations of metal nanoparticles and their composition, combined with traditional fertilizers (NPK), for enhancing soybean productivity. The objects of the study were varieties of soybean recommended for the forest-steppe ecoregion of Ukraine: ultra-early and early maturing Annushka and Ustya, respectively. The results obtained indicate the feasibility of using of a colloidal solution of metal nanoparticles as fertilizer due to its properties (phase composition, size) in agricultural technologies for soybean, which improves the productivity of this crop.
