This article investigates the impact of using wild-grown licorice (sweet licorice) plant waste in the soil on plant growth in the Saatlı region. Licorice waste naturally possesses many beneficial properties and can be reused in various fields, including agriculture. In this study, the growth processes of plant seedlings were observed concerning the application of untreated licorice waste and biochar in the soil. Three different experiments were conducted: the first involved 2g and 4g of untreated licorice waste, the second involved soil enriched with biochar, which is obtained from licorice waste, and the third involved soil without any fertilizers. In each experiment, plants were sown under the same conditions, and irrigation was carried out for seven days. The results for days 7 and 14 were also calculated. The study results indicated that the development of wheat grown with licorice waste varied at different levels. The results of the research show that biochar made from licorice waste and the application of licorice waste in the soil have a positive effect on seedling germination and growth. Plants grown in biochar-enriched soils exhibited better health and growth, while some challenges were observed in soils treated with untreated licorice waste. In conclusion, the reuse of licorice waste in agriculture can enhance soil fertility and may be beneficial for obtaining sustainable yields in farming.
