Abstract / Excerpt:

The study consisted of a series of chemical analyses to determine the suitability of urea-formaldehyde sediments for fertilizer use. The sampling point is the depository area of sediments in Borden International, Philippines, Toril, Davao City. The period of experimentation was from October, 1989 to January, 1990. The results of the determination revealed that the sludge material shows homogeneity of variance within the limits of three months. The period of sampling has little orn o effect on the activity index and the nitrogen content of the sample. However, the nitrogen content of the sediment is significantly less than the standard value set for ureaform types of fertilizers. The data further indicated that the activity index of the sediment falls below the standard level set by the Association of American Fertilizer Control Officials. Based on the findings of the present study, it is concluded that the Borden urea-formladehyde sediment is a poor source of fertilizer material.
