This contribution is focused on superabsorbent materials based on polymerization of partially neutralized acrylic acid. Several types of superabsorbents were prepared. They differed by content of inorganic (NPK fertilizer) and organic (lignohumate) nutrients for their release in soil systems. Superabsorbents were characterized from point of view of their swelling capacity in order to evaluate their ability to control water management soil. Gradual release of incorporated nutrient into water was monitored in time and complemented by measurements of pH and conductivity, UV-VIS, ICP-OES and Ion chromatography. It was found that the nutrients were released from superabsorbents for the duration of several days in the dependence on the type of prepared superabsorbent. In conclusion, simple pot experiments with corn were realized. Corn was grown in presence of each type of superabsorbent and even without it to get differences not only between samples but between samples and corn itself. It was confirmed that the application of superabsorbents can improve soil properties, water management, nutrient uptake, and growth of plants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
