Abstract:
Soil is both a support and a nutrient source for the development of living organisms. Composts
based on faecal sludge and vegetable wastes were tested on okra to see the proportion of organic
matter and nutrients in the soil after two seasons. Thus the control, non-composted faecal sludge
and chemical fertiliser were compared with the other treatments T0, T1 and T2. Physicochemical parameters such as pH, electrical conductivity, organic matter, nutrients Carbon,
Nitrogen, Potassium, Phosphorus and grain size were analysed. The results showed an increase
in organic matter content from the beginning (As = 0.52%) with 1.72%, 1.9% and 1.4% for the
soil samples that were amended with T0, T1 and T2 respectively. Thus the pH values are neutral
for treatments T0, T1 and T2. The electrical conductivities are between 33-47µs/cm. Mineral
elements such as A (0.08-0.1%), P (21.7-29.6%), K (0.02-0.03%), are satisfactory for T0, T1 and
T2. The C/N ratio is between 9.5-10.4 and below 12. |
