According to researchers, the estimation of soil carbon discharge is critical for climate change

More carbon is stored in the soil of the Earth than there is carbon stored in the atmosphere, which is a significant difference. A major amount of the carbon in soil is in the form of organic carbon, which is referred to as soil carbon. Humans have an impact on how quickly organic carbon can be created or lost in soils, which is different from the impact of inorganic carbon on soils.

To be precise, since the beginning of agricultural production approximately 10,000 years ago, agriculture has been responsible for releasing a considerable amount of soil organic carbon into the atmosphere as carbon dioxide, which has contributed to global climate change.

As a result, it is critical to estimate the quantity of soil organic carbon present in agricultural fields in order to better understand the carbon cycle and design sustainable management strategies. This is done in order to reduce carbon emissions from agriculture and to sequester carbon from the atmosphere into the soil in order to mitigate or reverse the climate impact of agriculture.

In order to maximise soil organic carbon productivity, researchers at the University of Illinois at Urbana-Champaign believe that accurate and efficient assessment is important. Soil organic carbon estimates are required by governments in order to develop sustainable management practises, while soil organic carbon estimates are required by farmers to participate in the newly established carbon credit markets.

Soil sampling followed by laboratory evaluation is the most traditional and reliable method of determining soil organic carbon content. However, it is critical to understand which areas of the field need to be sampled before beginning. And the number of samples that must be collected in order to obtain an accurate estimate.

Meanwhile, each additional soil core represents a major investment in terms of money and manpower, and the uncertainties associated with optimising samples might result in significant additional expenses.

Researchers from the SMARTFARM Project of the U.S. Department of Energy assessed methodologies for estimating soil organic carbon in a new study published today.
