Aplikace superabsorbentů do půdy a její vliv na růst rostlin / Application of superabsorbents in soil and its influence on plant growth

This thesis is focused on description of superabsorbents with controlled released of nutrients, specifically macronutrients nitrogen, phosphorus and kalium. Superabsorbents are polymers, mostly acrylic acid polymers, that can absorb huge amount of water without dissolving in it. In its structure they can hold water and thanks to this they are very perspective materials for agricultural usage. Experimental part was focused on growing corn with use of superabsorbents and control samples without use of superabsorbents. Plants were growth for 3 time periods, specifically 46, 60 and 74 days. During the experiments, plats were growth without water stress and in controlled conditions in growing box under UV lamp that simulated day and night by turning on and off after 12 hours. At the end, an image analysis was performed in HARFA program, from which we got information about branching of the roots. Results were supplemented by soil and plants analysis.
