Abstract

This study was carried out in Bauchi state northern guinea savanna agro-ecological zone of Nigeria to determine the chemical and microbiological characteristics composts. The composts materials consisted of three plant residues and two animal manures. The treatments were factorially combined to give four treatments. The method of composting adopted was the pit methods using 1.5 m × 1.5 m × 1 m length, breadth and depth, respectively. Total microbial count was determined by serial dilution of the sample using nutrient agar. The colony counted and data collected were subjected to statistical analysis using genstat statistical package. The result showed variations among the treatments in all the parameters tested. Treatment one (T1) presented the highest microbial counts (11cfu/g for bacteria) and (59 cfu/g for fungi), while the treatment T2 produced the lowest counts (4 cfu/g for bacteria) and (11 cfu for) fungi). Treatment T had the highest organic carbon (26.63 mg/kg and available P (33.66%), while Treatment T3 had the highest pH (8.21) but it was similar to that of T1.The highest water holding capacity (WHC) (51%) was observed in T1.Total N was highest in T3 (1.25 gkg-1).


Key words: Compost, plant residues, animal manure, bacterial counts and fungal counts.
