One of the main issues that we are facing today is to provide our growing population with quality food products. This, in turn, requires the implementation of such important factors as the development of agriculture, the transition to an intensive farming system, increasing soil fertility and thus obtaining high and quality crops. One of the important factors in the efficient use of agricultural land and increasing soil fertility is the joint use of local and mineral fertilizers in scientifically based proportions. However, today there is a shortage of local and mineral fertilizers. In addition to solving these shortcomings, maintaining and increasing soil fertility, the use of non-conventional agro-ores, organic fertilizers and composts in addition to mineral fertilizers has been proven in many studies. In the process of using composts, good water and nutrient regimes in the soil are necessary factors for plant growth. Composting of various wastes (waste of licorice) increases the supply of organic fertilizers, while preventing environmental pollution.
