This data report has been generated by a query to the table in which the Soil Carbon Challenge data is stored. To query the table, type the plot or project ID in the box below and click generate. The results will display below. We encourage you to print your report.
For baseline data, the data is self-referential. It does not mean that your management is good, bad, or indifferent. It is a starting point of repeatable monitoring. By repeating this monitoring in several years, change in soil carbon can be detected and measured.
Because soils may vary considerably over short distances, the data may not be applicable to an entire pasture, field, or farm.
The tops and bottoms of soil probe samples (depths) are reported in centimeters (0 cm = soil surface).
Percent total carbon is reported. Remember, soils may contain significant percentages of inorganic carbon (carbonates, CaCO3, caliche), particularly high pH soils and soils that have formed on limestone. It is common for the percentage of carbonates to increase with depth, and for the C/N ratio to increase. Where carbonates are present, the total carbon test does not translate to organic matter. However, the change in total carbon over time can usually be attributed to changes in organic matter, and that is what the Soil Carbon Challenge is designed to detect and measure.
For soils that do not contain carbonates, multiply by 1.7 to approximate the percentage of organic matter.
The date of each sample or observation, and the person reporting it or analyzing it, are noted for each data row. In general, data appear in boxes, and blank boxes indicate that the fields are blank. Care has been taken to ensure that these observations can be repeated with consistency in the future. For methods used, see soilcarboncoalition.org/files/MeasuringSoilCarbonChange.pdf.
