Sludge discharged from seafood processing factories directly into the environment can lead to environmental pollution. Research on the use of seafood processing sludge as compost for agriculture in the Mekong Delta is encouraged. The objectives of this study were (1) to evaluate the chemical composition of seafood processing sludge after composting for 60 days and (2) to evaluate the growth of Tagetes patula L when planted with composted sludge. |
