Improving Soil Quality and Crop Yields Using Enhancing Sustainable Rice Straw Management Through Microbial Enzyme...

Area of Science:

• Agricultural Science
• Environmental Science
• Microbiology

Background:

• Burning rice straw causes environmental pollution, soil degradation, and increased CO2 emissions.
• Current rice straw management practices often lead to negative environmental impacts.

Purpose of the Study:

• To develop and evaluate a microbial treatment for post-harvest rice straw decomposition.
• To assess the economic and yield benefits of using microbial products for rice straw management.

Main Methods:

• A field experiment was conducted in Dong Nai province, Vietnam, comparing four models: no treatment, Bio Decomposer, NTT-01, and NTT-02.
• Microbial products secreting cellulase enzymes were used to break down rice straw cellulose.
• Each experimental field measured 650 m².

Main Results:

• Microbial treatments significantly reduced straw decomposition time within 14 days, achieving up to 80% decomposition.
• Decomposition rates were nearly double compared to untreated rice straw.
• Cultivation costs were reduced by 60%, and crop yields increased by 20%.

Conclusions:

• Microbial treatment of rice straw is an effective method for sustainable agriculture.
• This approach reduces agricultural waste, improves soil health, and enhances farmer income.
• The findings support broader applications of microbial treatments in agricultural waste management.
