Saphon !
Trois principales choses que les plantes ont besoin : azote , phosphate et
potassium qu'on écrit par les lettres N , P, K . et oligoéléments .
Tous les engrais sont faits à partir de cette base . On recherche dans la
nature tout ce qui peut apporter ces 3 éléments N, P,K aux plantes et on
trouve
dans différents humus , antreang khèt , boues de vaches , etc....
Pour répondre à tes questions :
- Antreang khèt donnent de l'azote
- déchets de poissons donnent azote et phosphate
- Toeuk chroam sous les maisons : donnent N,P, K mais en petite quantité .
Mais mieux que rien du tout et permet d'améliorer l'écologie .
Amitiés
