Measuring And Reporting Soil Organic Carbon Agriculture And Food Soil carbon sequestration (soc) is the process of transferring co2 from the atmosphere into the soil in the form of organic carbon. this process begins with photosynthesis, where plants convert atmospheric carbon dioxide into organic compounds. these compounds are then incorporated into the soil through plant residues and root exudates. Typically, the organic carbon content of wa dryland agricultural soils is between 0.7% and 4% (figure 2), although soc can be as low as 0.3% for desert soils and as high as 14% for intensive dairy soils. most organic matter is located near the soil surface. in south west wa, about 60% of organic matter in the top 30 cm of soil is located in the.

How Organic Matter Creates Sustainable Carbon Friendly Agriculture Soil carbon is sampled by taking soil probe samples similar to those farmers already take to measure soil fertility, but to measure carbon for carbon credit programs, the probe is usually inserted a full foot, or about six inches deeper than for soil fertility tests. a bulk density test is also taken, to determine the amount (tonnage) of carbon. Soil tests for organic carbon normally report a % total soil organic carbon. using a measure of bulk density the amount of carbon per hectare in a given depth of soil can be calculated as shown. calculation. the amount of organic carbon to 10cm depth in soil with a carbon value of 1.5% and bulk density of 1.3g cm 3 is:. Form of carbon in soils. soil organic carbon (soc) refers specifically to the carbon component of soil organic matter, so laboratories measure and report on soc. soc is an indicator of healthy, productive soils and agricultural practices that retain and increase the amount of soc, also improve productivity and sequester atmospheric carbon. Organic matter (%) = total organic carbon (%) x 1.72. this conversion factor assumes organic matter contains 58 % organic carbon. however this can vary with the type of organic matter, soil type and soil depth. conversion factors can be as high as 2.50, especially for subsoils. total organic carbon can be further defined as fractions that vary.

The main component of som is carbon, also known as soil organic carbon (soc). this carbon constitutes the largest terrestrial carbon pool and makes soils integral to our planet's carbon cycling. on a global scale, the top 30 cm of soil contains more carbon than the atmosphere and vegetation combined. Loss of soc accelerates soil health problems such as soil erosion and decreases soil aggregation. this chapter explores those issues and discusses various soc measurement methods. soil organic carbon is an extremely important soil health indicator because it influences almost all soil biological, chemical, and physical properties and processes.
