  • Food waste compost with high salt content produced by aerobic digestion, but concerns about application of cropland. To address this issue, food waste is being composted by mixing it with livestock manure, which has a lower salt content. Therefore, this study aimed to evaluate the growth characteristics of red pepper and soil chemical properties for continuous application with different amounts of food waste compost with manure (FWC). Treatments were consisted of no fertilizer (NF), inorganic fertilizer (N-N-P2O5-K2O, 19.0-11.2-14.9 kg 10a-1), and inorganic fertilizer + food waste compost with manure (NPKFWC). FWC treatment was applied at three treatment rates based on soil organic matter content: 900 kg 10a-1, 1,800 kg 10a-1, and 2,700 kg 10a-1 ( referred to a s FWC 1, 2, 3 , respectively). As a r esult of the red pepper yield was about 1.8 times higher in NPKFWC 1 and NPKFWC 2 than that in the NF, but decreased in the NPKFWC 3, 300% of the recommended FWC application rate. Yield decreased in all FWC treatments with continuous application for three year and also decreased about 40% from 3,265 kg 10a-1 in the first year to 1,948 kg 10a-1 in the third year. For the soil chemical properties, the content of soil organic matter, available P2O5, and exchangeable cations increased in the FWC treatments, and were higher than the NF. Exchangeable sodium in all treatments was increased slightly compared to the soil before used, and no significant salinization was observed in the FWC. This study confirmed that excessive use of FWC not only reduced nutrient use efficiency, but also decreased the red pepper yield. Therefore, it is concluded that optimum usage of FWC is effective for agroecological impacts.

  • This study was conducted to evaluate the properties of mixtures of mixed organic fertilizer (MOF) and various organic sources such as livestock manure compost (LMC), dried compost of poultry manure (CPM), dried food waste powder (FWP) and amino acid by-product fertilizer (ABF) and their influences on growth of lettuce and Chinese cabbage. The content of N, P2O5 and K2O of mixture of MOF, LMC and FWP (MLF) was 3.6~3.9%, 2.1~2.2% and 1.3~1.4%, respectively. Lettuce dry weight of MLF3 treatment blending with MOF (60%), LMC (10%) and FWP (30%) was increased by about 29% than that of MOF. The content of N, P2O5 and K2O of mixture of MOF, CPM, FWP and ABF (MCFA) was 4.5~4.7%, 1.7~1.9% and 1.3~1.4%, respectively. Compared to MOF, growth factors of lettuce and Chinese cabbage in the MCFA treatments were not significantly deferent. These results indicated that MLFs and MCFAs, the mixtures of respectively organic sources and MOF, could be applied as orgnic fertilizer in the cultivation of lettuce and Chinese cabbage, and were expected that LMC and ABF might be used as another sources of organic fertilizer.
