  The present invention relates to agricultural articles which keep their properties during the use and degrade later on, until total disintegration and disappearance of the plastic. The invention further relates to a method for controlling the weathering resistance and the degradation of agricultural articles. The desired effect is obtained with specific combinations of degradant metal salts and stabilizers. The agricultural article of the present invention comprises an organic polymer, an organic salt of Fe, Ce, Co, Mn, Cu or Vd and one or more sterically hindered amine compounds.
