DUMITRITA IOANA OPRICA, TRAIAN MIHAI CIOROIANU, MIHAELA LUNGU, IRINEL ADRIANA BADEA A NEW ECO - FRIENDLY FOLIAR FERTILIZER WITH BONE GLUE SUITABLE FOR CROPS OF MAIZE AND SUNFLOWER
The main objective of the present work was the preparation and characterization of a new foliar fertilizer which contains bone glue as an organic physiologically active source. The association of the bone glue with macro and micronutrients from the common foliar fertilizer ensures a synergic effect on the production and quality of maize and sunflower. The survey of the evolution of each crop together with the qualitative and quantitative analysis of the physical and chemical characteristics of the leaves and seeds showed that the new foliar fertilizer increased the nutrients uptaken by plants. Moreover, the analysis of soils involved in this experiment revealed that this new fertilizer acts as an eco-friendly one.
