<![CDATA[The annual rice planting cycle produced 6.73 tons of dry straw per hectare. Rice straw had beneficialnutrients for plants, but farmers often burned or buried it to reduce waste and enhance soil fertility. Becausestraw was hard to decompose, additional decomposers like bacteria were needed. This study aimed toinvestigate the short-term impact of rice straw management on soil organic carbon (C-organic) and the C/Nratio. The experimental design used was Nested Design. The study involved three straw managementtreatments: burning (BR), straw incorporation without EM4 addition (S0), and straw incorporation withEM4 addition (S1). Laboratory analysis was conducted on the C-organic and C/N ratio parameters.Differences in soil parameters observed before and after straw management treatments were analyzed usingthe Wilcoxon Signed Rank Test. The analysis showed an increase in C-organic after treatment: 29.7% forburning, 10.9% for straw incorporation, and 10.2% for straw incorporation with EM4. The rise in C-organicafter straw management treatments is due to the mineralization of soil organic matter. This mineralizationis indicated by average C/N values below 20, although the C/N ratio after burning increased by 56% andafter straw incorporation with EM4 increased by 0.35%. The average C/N ratios from all treatments rangedfrom 9.1 to 16.8. In the short term, all three straw treatments can increase organic carbon and C/N ratiosbelow 20.]]>
