Agricultural product (1) comprises: an agricultural liquid composition (11)； and a casing (10) containing the liquid composition, where the casing is constituted of a water-insoluble oxo-biodegradable polymeric material. An independent claim is included for preparing the agricultural product comprising a substantially agricultural liquid composition (11) and the casing, where the casing is constituted of a non polymeric material and substantially spherical form, comprising: supplying two films of similar material polymer； preparing the substantially liquid composition； laying films in an encapsulating unit comprising two molding drums, each comprises a cylinder in which many hemispherical cavities are formed, where the drums are arranged so that their axes are parallel and cylinders are adjacent, and the films are continuously rolling in encapsulation unit tangentially on the cylinders； transforming films into parts of capsule to form substantially hemispherical capsule by counterrotary movement of the cylinders of molding drums and simultaneously introducing the composition for agricultural use in the parts of capsule； and closing the capsule to form the casing filled with the agriculture composition, where films of water-insoluble and oxo-biodegradable polymer material is provided and the films are heated at 90-140[deg] C, prior to providing films on cylinders of drums.
