Abstract: The present invention relates to a composition for fertilizing desert land and making it agricultural, characterized in that it comprises animal excrement, plant waste, bentonite in an amount greater than 10%, essential macronutrients, essential micronutrients, agricultural sulphur, algae and effective microorganisms. The invention will be of use in agriculture, in particular for increasing the yields of soils that are not very fertile, such as deserts which form most of the countries of North Africa and the Middle East. Deserts are among the only lands which are not polluted because of overgrazing and the exhaustive use of chemical fertilizers. It is therefore essential to respect these lands and to limit the pollution thereof. The composition according to the invention comprises animal and plant waste. The recycling of this agricultural waste contributes to improving atmospheric and soil pollution by limiting the burning of waste that is harmful to the environment and to human health.

Abstract: The present invention concerns device for producing green coal for agricultural use from organic agricultural materials comprising: a container (5) suitable for receiving the organic materials, an enclosure (1) enclosing the container (5) and delimiting an intermediate space around the container (5), a system for heating the intermediate space and a rotary stirring system configured to stir the organic materials placed in the container (5), characterised by the fact that the rotary stirring system comprises a plurality of blades (15) that are fixed relative to the container (5) and a plurality of blades (14a, 14b) that are mobile in rotation relative to the container (5), the plurality of fixed blades (15) being distributed between at least two stages of fixed blades (15) along the axis (13) of rotation, the plurality of mobile blades (14a, 14b) being distributed between at least two stages of mobile blades along the axis (13) of rotation, the stages of fixed blades and the stages of mobile blades alternating
