Abstract
(EN)
The subject of the invention is a process for producing compost of high water absorbing and retaining capacity, particularly by using compost material produced from wood industrial waste material which improves the soil fertility. During the process of the invention process the compost of wood industry origin transformed to plant absorbable manure and decomposed under aerobic conditions known per se to a water content of 30 to 35 %, sieving and putting the dehydrated product in prism while adding 1.5 to 3.0 % by weight water absorbing and retaining adjuvant is added to the compost during the prism formation process, turning over the prism several times by power machine, homogenising the mixture and covering with a black foil, its water content controlled and maintained at 30 to 35 % and, if desired, adjusting the water content within the above level. The process of the invention is used in agriculture.

Procédé de production de compost à capacité élevée d'absorption et de rétention de l'eau, notamment à l'aide de matières compostées obtenues à partir de déchets de l'industrie du bois qui améliorent la fertilité des sols. Selon ce procédé, on transforme le compost provenant de l'industrie du bois en engrais pouvant être absorbés par les plantes, on provoque leur décomposition dans des conditions aérobies connues en soi jusqu'à obtention d'une teneur en eau comprise entre 30 et 35 %, on tamise le produit déshydraté et on lui donne la forme d'un prisme tout en y ajoutant de 1,5 à 3,0 % en poids d'un adjuvant absorbeur et rétenteur d'eau au cours du processus de formation du prisme, on retourne le prisme plusieurs fois à l'aide d'une machine motorisée, on effectue l'homogénéisation du mélange et on le recouvre d'une feuille noire, on règle sa teneur en eau de manière à la maintenir à une valeur comprise entre 30 et 35 %, et, le cas échéant, on modifie la teneur en eau afin qu'elle soit comprise entre ces limites. Ce procédé trouve application dans l'agriculture.
