The determination of plant nutrition content and comparison of ingredient benefits in liquid organic fertilizers and liquid organic fertilizers with amino acid

The most important process to maximize the efficiency of agricultural production is the use of correct fertilizers. It is known that chemical fertilizers used unconsciously and in an unbalanced manner cause an increase in production costs, as well as the use of such fertilizers poses a threat to plant and animal health. It is not possible to obtain the desired yield and quality product with chemical fertilization or chemical fertilization in addition to insufficient organic fertilization. In recent years, the usage rates of organic, organomineral, soil regulators and microbial fertilizers have increased in addition to chemical and farm fertilizers in order to increase productivity in plant production. When the results of the literature are evaluated, it is predicted that the liquid organic fertilizer consumption of the producers has increased and may increase in the future. Although organic fertilizers play an important role in improving the biological, physical and chemical structure of the soil, the use of these fertilizers is below the desired level. Turkey imports of fertilizer and manure is dependent on foreign countries for the supply of raw materials. In this thesis study, the characterization of imported liquid organic fertilizers of different types was carried out according to the methods specified in the Regulation on Organic, Mineral and Microbial Originated Fertilizers Used in Agriculture dated 23 February 2018 and numbered 30341. It is aimed to create possible formulation and product prescription information for possible domestic and national production in reducing foreign dependency in fertilizer use.
