1. Summarizing, handling internal and external information regarding land survey, assessment of quality and potential of land in Vietnam

According to Article 13 of Circular 11/2024/TT-BTNMT stipulating the summarization, handling of internal and external information regarding land survey, assessment of quality and potential of land in Vietnam as follows:

Summarizing and handling survey results

- Reviewing, comparing, modifying, and supplementing information to ensure accuracy and consistency of survey results between the field survey map with the profile description, survey image, soil specimen, and survey data table;

- Creating a statistical table of the profile survey list and soil samples; arranging soil specimens, soil samples, and profiles according to the list; selecting soil samples for analysis; handing over soil samples to the analysis unit.

Soil sample analysis

- Analysis criteria include: total microorganisms; mechanical composition (sand, silt, clay); bulk density; specific gravity; soil acidity (pHKCl); total organic matter (OM%); total nitrogen (N%); total phosphorus (P2O5%); total potassium (K2O%), CEC. For coastal areas, additional total sulfur and total soluble salt criteria are analyzed.

- Soil sample analysis method according to the provisions in Section III Part A of Appendix II issued with Circular 11/2024/TT-BTNMT.

Summarizing, handling information for soil quality assessment

- Identifying and classifying soil quality assessment criteria as prescribed in Section I Part C of Appendix II issued with Circular 11/2024/TT-BTNMT;

- Summarizing geographical survey results including types of soils and soil thickness;

- Summarizing geographical survey results on terrain (slope or relative terrain);

- Summarizing analysis results on physical, chemical, and biological properties of soil according to types of soils and types of land;

- Summarizing climatic survey results (rainfall, total thermal accumulation, number of dry months).

Summarizing, handling information for assessing the land potential for current land types and land use orientation

- Identifying and classifying the land potential evaluation criteria as prescribed in Section II Part C of Appendix II issued with Circular 11/2024/TT-BTNMT;

- Identifying the area of each type of land in each survey plot;

- Summarizing water policies survey results by land type in each survey plot;

- Summarizing economic efficiency evaluation results for each plot and each area in the survey site;

- Summarizing social efficiency evaluation results for each plot and each area in the survey site;

- Summarizing environmental efficiency evaluation results for each plot and each area in the survey site;

- Summarizing, handling information to evaluate the land potential for different types of land to serve land use orientation.

Building a report on summarization and handling of internal and external information.

2. Summarizing, handling internal and external information on land degradation survey and evaluation

Summarizing and handling survey results

- Reviewing, comparing, modifying, and supplementing information to ensure accuracy and consistency of survey results between the field survey map with the degradation forms description, survey image, and survey data table;

- Selecting analysis results as prescribed at point d, clause 3, Article 13 of Circular 11/2024/TT-BTNMT for upper layer soil samples of profiles.

Summarizing and handling information for land degradation assessment

- Identifying and classifying land degradation assessment criteria as prescribed in Part C of Appendix III issued with Circular 11/2024/TT-BTNMT;

- Summarizing survey results as prescribed at points b, c, d, e clause 3 and point c clause 4, Article 13 of Circular 11/2024/TT-BTNMT;

- Summarizing survey results for degraded soil evaluation such as nutrient-depleted land; eroded land; drought, desertification, and sedimentation land; compacted and laterite land; saline land; acid sulfate soil according to the classification criteria prescribed at point a, clause 2, Article 21 of Circular 11/2024/TT-BTNMT.

Building a report on summarization and handling of internal and external information.

More details can be found in Circular 11/2024/TT-BTNMT effective from August 1, 2024.
