摘要

Poly(methylene-co-cyanoguanidine), PMCG, is an oligomeric polycation that has found its application in the waste-water treatment as well as in preparation of polyelectrolyte complex microcapsules for biomedical purposes. Considering the nitrogen-rich composition of repeating unit, PMCG may be a valuable polycation utilized as a novel slow-release fertilizer. The aim of this study was to evaluate the potential of PMCG as a nitrogen fertilizer during its 6-month incubation in the soil. Monocotyledonous oat (Avena sativa) and dicotyledonous radish (Raphanus sativus L.) were selected as representative model plants for plant growth test. The effect of PMCG on plant growth and development was dependent on both the PMCG concentration and time of incubation. An increase in the nitrogen amount in green parts of plants demonstrated the uptake of the plant-available form of nitrogen released from PMCG incubated in the soil. This resulted in an increased percentage of fresh matter and shoot height of the tested plants during their exposure to PMCG. Ecotoxicological impact of PMCG in the soil during incubation period against bacteria Allivibrio fischeri and crustacean Heterocypris incongruens was also assessed. PMCG was found as the potential polymer fertilizer that does not require special treatment and can be used as it is for the prolonged release of nitrogen in agriculture.
