Integrating degraded or contaminated lands into food production chains poses significant challenges and expenses. This study explores a novel technology for cultivating vegetables on degraded lands employing vegetal substrates in the form of bales. These multi-layered vegetal structures are strategically designed to offer essential support, nutrients, water, warmth, and protection against pests for the cultivated plants. The fertile layer within these structures was produced through composting vegetable waste produced from horticulture. The protective surface of the bale was made from a mixture of agricultural wastes, ensuring both a resilient structure and permeability. The structure was enhanced with two layers made of recycled cotton, aimed at retaining moisture efficiently. The research showed that the adopted technological solution can yield a 30-40% improvement in production of tomato and eggplant. Moreover, it demonstrates high adaptability, being easily applicable for crops establishing in contaminated, degraded environments, or even on concrete surfaces.
