Boosting nitrogen fertilization by a slow releasing nitrate-intercalated biocompatible layered double hydroxide-hydrogel composite loaded with Azospirillum brasilense.

ABSTRACT: Indiscriminate use of chemical fertilizers leads to soil environmental disbalance and therefore, preparation and application of environment-friendly slow-release multifunctional fertilizers are of paramount importance for sustainable crop production in the present scenario. In this study, we propose a slow-release multifunctional composite nitrogen (N) fertilizer, which possesses the ability to supply plant accessible N in the form of ammonium (NH₄ ⁺) and nitrate (NO₃ ^-) to improve nitrate assimilation coupled with zinc (Zn, a major micronutrient for plants in the soil) after its degradation. For this purpose, NO₃ ^--intercalated zinc-aluminum (Zn-Al) layered double hydroxide (LDH) was synthesized using a co-precipitation pro
