Summary:The invention relates to a process for producing hybrid hydrogels to be used in agriculture. According to the invention, the process consists in the copolymerization of acrylic acid with N,N'- methylenebisacrylamide in the structure of the aqueous bacterial cellulose, while possibly adding urea aqueous solution with a concentration of 440...490 g/l or an aqueous solution of NPK liquid fertilizer wherefrom hybrid hydrogels having characteristics of water and fertilizer controlled release result. Invenţia se referă la un procedeu de obţinere a unor hidrogeluri hibride, utilizate în agricultură. Procedeul conform invenţiei constă în copolimerizarea acidului acrilic cu N, Nmetilenbisacrilamidă în structura celulozei bacteriene apoase, eventual se adaugă o soluţie apoasă de uree cu concentraţia de 440...490 g/l sau o soluţie apoasă de fertilizant lichid NPK, din care rezultă hidrogeluri hibride, având caracteristici de eliberare controlată a apei şi a fertilizantului.
