Labeled Organic Agriculture, Château Léoube has obtained the High Environmental Value certification, the highest in this field, for its 1,384 acres (560 ha) estate. Terre & Humanisme also carried out a study of the soils, water, flora, and fauna of the estate in order to implement a long-term agroecological strategy plan. It notably aims at reducing the pressures on the environment by limiting the use of inputs (fertilizers) and waters resources, as well as promoting crops diversification and rotation for autonomous agriculture respectful of the soils, groundwater tables, and air.
