Composting of palm press fibre
AbstractThe effects of composting palm press fibre alone, palm press fibre supplemented with poultry layer deep-litter and urea, and palm press fibre supplemented with poultry broiler floor-litter and urea were studied. The initial C:N ratios of the three mixtures were 40:1, 33:1 and 26:1, respectively. After 8 weeks of composting the C:N ratios of the mixtures were 26:1, 17:1 and 16:1, respectively. The temperature in the heaps rose to 60–70°C in the first 3 weeks of composting but stabilized at between 30 and 40°C after 8 weeks. The ratio of thermophilic to mesophilic fungi increased during composting, and even after the compost had cooled the thermophilic fungal counts remained high. The mesophilic bacteria were not influenced by temperature fluctuation in the heaps and bacterial numbers remained high even during the peak heating phase. Decreases in cellulose and carbon corresponding with increases in nitrogen, lignin and ash were evident after composting. Preliminary studies indicate that the compost mixed in sand and loam may enhance crop production.
