Morocco produced more than 50000 tons of the chicken droppings of which its majority of 95% are used as source of amendment for agricultures without preliminary pre-treatment.

A higher content nitrogen (4,48%) which can be lost by leaching or streaming then is found partly in the ground water and surface waters thus causing a specific nitrogenised pollution and diffuse. The content of COT is of the order (16,5%) which can cause an organic pollution. The heavy ions and metals present a very high contents (Pb: 2,37 ; Zn: 196,35 ; Cu: 70,90 and K: 32,86 mg/kg), consequently presence of risk potential of dissolution of these elements in rain water and being to export towards the sources of water. The chicken droppings are charged in pathogenic bacteria mainly the staphilococca and enterobacteries which present contents very high with (114.108 and 154. 106 UFC/g).

Abstract: (french)
Le Maroc a produit plus de 50000 tonnes des fientes de poulets de chair dont plus de 95 % sont utilisées comme source d'amendement pour les agricultures sans prétraitement préalable. Lors de la recherche des caractéristiques physiques, chimiques et microbiologiques de ce type de déchet, on a remarqué qu'il présente des risques potentiels de contamination des eaux souterraines et superficielles. Une teneur élevé en azote (4,48 %) qui peut être perdue par lixiviation ou ruissellement puis se retrouve en partie dans les nappes phréatiques et les eaux superficielles provoquant ainsi une pollution azotée ponctuelle et diffuse. La teneur en COT est de l'ordre (16,5 %) qui peut provoquer une pollution organique. Les ions et métaux lourds présentent des teneurs très élevées (Pb : 2,37 ; Zn : 196,35 ; Cu : 70,90 et k : 32,86 mg/kg), par conséquent présence de risque potentiel de dissolution de ces éléments dans les eaux pluviales et être exporter vers les sources d'eaux. Les fientes de poulets sont chargées en bactéries pathogènes principalement les staphylocoques et entérobactéries qui présentent des teneurs très élevées avec (114.108 et 154. 106 UFC/g). Par conséquent une menace réelle pour les eaux. Ce travail ouvre de nouveaux horizons pour la recherche de traitement de ce déchet avant qu'il arrive à la source d'eau.
