• In Volume 3, Chapter 3, page 3.39, Corrected to: "... reaction will result in 0.379 tonnes of N₂O per tonne of glyoxal."
• In Volume 4, Chapter 1, page 1.16, Figure1.4, Categories 3D1 and 3D2 correctly reported under 3D
• In Volume 4, Chapter 2, page 2.36, Box 2.2, Replaced calculations in Box 2.2 with calculations in Box 2.2 from the 2019 Refinement
• In Volume 4, Chapter 3, page 3.39, Replaced Figure 3A.5.2 with Figure 3A.5.2 from the 2019 Refinement
• In Volume 4, Chapter 4, page 4.15, Corrected to: "The default values are given in Tables 4.7 and 4.8"

• In Volume 4, Chapter 11, page 11.16, Equation 11.8,
  
  Corrected to: “(Note: for Approach 1, ΔC_{mineral, LU} will have a single value for all land-uses and management systems. Using Approaches 2 or 3 the value for ΔC_{mineral, LU} will be disaggregated by individual land-use and/or management systems.)”
  
  Corrected to: “Step 3: For Approach 1, the value for FSOM is calculated in a single step. For Approaches 2 or 3, FSOM is calculated by summing across all land-uses and/or management system types (LU)”
• In Volume 4, Chapter 11, page 11.27, Equation 11.11, Removed the sentence: "Note: If a country is able to estimate the quantity of N mineralised from drainage/management of organic soils then include this as one of the N inputs into the Tier 2 modification of Equation 11.10" is just a repetititon of the same sentece provided for equation 11.10; however, it does not apply to equation 11.11"
