As part of its commitment to environmental protection, expanding green spaces, and ensuring clean air, Tashkent State Agrarian University has carried out another ecological initiative. On the university campus, small cavities were created in the trunks of ornamental trees at a 45° angle and a depth of 3–5 cm. Through these cavities, biological fertilizers containing N P K as well as macro- and micronutrients were administered using specialized tools. This innovative method promotes the healthy growth of trees and positively contributes to the ecological sustainability of the green area.
