Addressing incomplete soil sample data in soil enrichment protocol projects

A system comprising:

• a soil attribute database;
• a soil sample location database;
• a regional soil data database;
• a computing node comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor of the computing node to cause the processor to perform a method comprising:
• receiving a plurality of soil sample locations within a land area from the soil sample location database, soil attributes for at least some of the plurality of soil sample locations from the soil attribute database, and regional soil data of the land area from the regional soil data database;
• estimating soil organic carbon (SOC) emissions reduction of the land area;
• determining a plurality of pre-strata based on the plurality of soil sample locations and the regional soil data, wherein each pre-stratum of the plurality of pre-strata comprises a plurality of soil sample points across the land area;
• for each pre-stratum of the plurality of pre-strata:
• determining a potential for bias for the pre-stratum;
• and
• when the potential for bias is above a predetermined threshold,
• determining a plurality of post-strata based on the pre-stratum, wherein the plurality of post-strata are disjoint subsets of the pre-stratum;
• determining a total estimated emissions reduction of the land area based on the plurality of post-strata and the estimated SOC emissions reduction of the land area.

A computer program product for estimating greenhouse gas emissions comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• estimating soil organic carbon (SOC) emissions reduction of the land area;
• determining a plurality of pre-strata based on the plurality of soil sample locations and the regional soil data, wherein each pre-stratum of the plurality of pre-strata comprises a plurality of soil sample points across the land area;
• for each pre-stratum of the plurality of pre-strata:
• determining a potential for bias for the pre-stratum;
• and
• when the potential for bias is above a predetermined threshold, determining a plurality of post-strata based on the pre-stratum, wherein the plurality of post-strata are disjoint subsets of the pre-stratum;
• determining a total estimated emissions reduction of the land area based on the plurality of post-strata and the estimated SOC emissions reduction of the land area.
