Synthesis of controlled release hydrogels from dimethylacrylamide/maleic acid/starch and its application in lettuce cultivation

Nahit AKTAŞ

Over or under the application of fertilizers raises concerns about soil and environmental degradation, and the recently developed controlled application of fertilizers is the focus of addressing these concerns. In this study, we aimed to synthesize a new N,N-Dimethylacrylamide (DMAAm)-Maleic Acid (MA) - Starch (St)-based superabsorbent (p(DMAAm-co-MA-co-St) (DMSt(1))) and to evaluate the suitability of controlled release fertilizers in lettuce cultivation. HCl/NaOH were used to create negative and positive surface modifications of DMSt(1) and respectively, were named to be p(DMAAm-co-MA-co-Sta ...Более
