Enhanced efficiency fertilizers (EEFs) have gained ground in the fertilizer trade. However, most of the EEFs marketed are not biodegradable. Therefore, it is necessary to produce EEFs that biodegrade in the soil. In this work, we developed EEFs based on chitosan, carboxymethyl cellulose, and zeolite as support for macro and micronutrients. Zeolite enriched with fertilizer was added to the carboxymethyl cellulose to obtain mono and multielement casting films. Sequentially, for the first time reported in the literature, EEFs were produced from multilayer films by overlapping and hot-pressing. The release of ions, in water and soil, and the biodegradation of the prepared materials and the Basacote were evaluated. The developed EEFs showed similar macro and micronutrient release in water and soil compared with the Basacote, but the developed EEFs showed higher biodegradation. Therefore, we propose a new EEF with efficient results of release in soil, biodegradability, low cost, and easy preparation. (AU)
