Fuente: WIPO "organic farming" A system for providing nutrients to a plant may support the plant with the root system exposed and accessible in a controlled environment within a structure, effecting interaction between a carrier fluid and a soil-based medium to transport nutrients from the soil-based medium to targeted plants. The soilbased medium may comprise organic soil at or near grade level and/or other media at other elevations. In some embodiments, the system includes a structure that comprises a roof-mounted frame placed in a location that can expose portions of plants to natural sunlight and a lightweight, aerated, humiditycontrolled enclosure around the root system.
