ENHANCING NUTRITION, FOOD AND ENERGY SECURITY THROUGH BIOGAS TECHNOLOGY.pdf

The project culminates from works on BioDigester Technology for providing clean energy, healthy sanitation (Decentralised Sanitation, DeWaT) and Enhanced Agriculture Production using Organic fertilizers. The need for sustainable and healthy food production systems has paved way for the growing use of organic fertilizers and manure. Biogas Technology through the BioDigester effluent/slurry has proved to be a good source of organic fertiliser or manure. The organic fertilizer from BioDigesters is a good soil conditioner improving the soils' water retention and plants' water absorption characteristics. Crops grown from biofertilizers are free from chemical pollution and provide a source of good nutrition for human consumption.The slurry was dried and applied on three different crops with 3 replications of application rates namely 0%, 25%, and 50%. Compared to the control (0%), performance effect on the crop of the of the 25% was instant yet short lived while the 50% was gradual and the plant vigor was sustained for the duration of the period of observation. This was 2 months. Crops planted were Rape, Chinese Cabbage and Spring Onion. A vertical garden setting was used in the experiment.
