BACKGROUND: From year 2005, landfill for food waste has been prohibited. Also, according to London agreement in year 2013, ocean discharge for livestock manure, sewage sludge, and food waste has been regulated. Alternative way for food waste disposal is incineration. However, due to high moisture content, additional input for energy is needed. Therefore, effective way for food waste disposal such as application of food waste compost is needed.
METHODS AND RESULTS: Seven different treatments (Livestock compost, Food waste compost, Food waste + Livestock compost, Livestock compost + chemical fertilizer, Food waste compost + chemical fertilizer, Food waste + Livestock compost + chemical fertilizer and control) were applied to tomato crop. All treatments replicated with completely randomized design. Tomato growth treated with LC+NPK showed highest values for all parameters such as leaf length, leaf width and chlorophyll (O.D) compared to other treatments. Subsequently FWC+LC+NPK is followed. EC, OM contents, and CEC in soil treated with composts significantly increased.
CONCLUSION: To evaluate the effect of food waste compost application on tomato growth and soil chemical properties, we carried out field experiment treated with 7 treatments with 3 replicates. LC+NPK showed highest values for all parameters. Some parameters such as shoot length and total length for tomato was not significantly different between LC+NPK and FWC+LC+NPK.
