Pig farming has provided an important source of income for farmers. However, alongside its many benefits, animal husbandry also brings significant problems such as diseases and environmental pollution. Notably, the failure to safely treat livestock waste has serious impacts on both the environment and people. Integrated livestock models have been successful in minimizing pig herd pollution and increasing farmers' incomes. Reusing waste from pig farms to produce fertilizer for crops is essential in reducing environmental pollution. Livestock waste is a recyclable resource for crop fertilization, which can benefit family farms both economically and environmentally. Research and production of fulvic bio-organic fertilizer – amino acids from pig farm emissions – aim to protect the environment and promote sustainable development. An experimental model on the effect of foliar fertilizer on leafy vegetable crops was conducted in vegetable gardens in Hoc Mon district.
