title: Neural network assessment of the effectiveness of using fulvic acids in combination with mineral fertilizers on the productivity and quality of Aficion leaf lettuce grown in vertical hydroponics
abstract: Growing demand for environmentally friendly plant products stimulates the development of closed-type urban city farms. As an innovative business model, they effectively use the limited space of megacities, providing direct access to the market. Plants are grown vertically on hydroponics with automatic environment control. To improve product quality and reduce dependence on mineral fertilizers, their partial replacement with humic stimulants was studied. An experiment was conducted with lettuce o
