Sodyum karboksimetil selüloz (NaCMC) hidrojelleri, buğday çimi bitkisinin (Triticum Aestivum) büyümesinde potansiyel kullanım için hazırlandı. Su absorpsiyon ve jel içeriği (yüzdesi) özellikleri test edildi. Jel içeriği sonuçlarının aksine çapraz bağlayıcı içeriğinin arttırılmasıyla su absorpsiyonu azaltılmıştır. Hidrojellerin toprak uygulaması, toprağın su tutma kapasitesini arttırdı. Su ve toprakta hidrojellerin mangan salım davranışı incelendi ve salım değerleri çapraz bağlanma yoğunluğu ile azaldı. Mangan yüklü hidrojelin buğday çimi bitkisinin performansı üzerindeki etkisi de saksı deneyleri yapılarak incelenmiştir. Buğday çimi büyümesi, mangan yüklü hidrojellerin kullanılmasıyla belirgin olarak artmıştır. Hidrojellerin kullanılmasıyla bitki performansındaki artış, hazırlanan hidrojellerin tarım alanlarında kontrollü bir gübre sistemi olarak kullanılabileceğini göstermektedir.

Preparation of Sodium Carboxymethly Cellulose Hydrogel for Controlled Release of Manganese Micronutrient

Öz

In order to use potential in the development of wheatgrass plant (Triticum Aestivum), carboxymethyl cellulose sodium salt (NaCMC) hydrogels were prepared. The characterization of synthesized hydrogels was examined. Water absorbency and gel content properties were influenced the amount of crosslinker in hydrogels. The water absorbency was negatively affected with crosslinker on the contrary gel content. The application of hydrogels improved the water retention capacity of soil. The manganese release was examined in water and soil and the release slowed down with crosslinker. Manganese-loaded hydrogels were used for growing the wheatgrass plant. The growing of plant was positively affected with using manganese-loaded hydrogels. These results suggest that manganese-loaded hydrogels could be utilized as a controlled fertilizer system in agriculture areas.
