Carbon Credits in Soil: A Path to Sustainability with the PRIMACS™ SNC-100 Analyzer


As the global concern over climate change intensifies, the quest for sustainable solutions to combat rising greenhouse gas emissions has become paramount. Among the innovative approaches gaining traction is the concept of carbon credits, which promotes carbon dioxide (CO2) reduction and removal from the atmosphere. This financial instrument plays a vital role in the carbon offset market and encourages activities that lead to a cleaner and more sustainable environment. Of particular interest is the application of carbon credits to soil management where soils possess the remarkable ability to act as carbon sinks. Through natural processes like photosynthesis, plants absorb CO2 and store it as organic matter in the soil, offering a means to mitigate climate change by reducing atmospheric CO2 concentrations. This article explores the world of carbon credits in soil, highlighting their significance, the quantification of the amount of carbon, and the instrumental role of Skalar's PRIMACS™ SNC-100 analyzer in accurately determining carbon types as well as the total amount of carbon in the soil.

Carbon Credits in Soil

To combat climate change effectively, it is crucial to encourage and reward activities that reduce greenhouse gas emissions. Carbon credits provide a real, market-driven incentive for sustainable land management practices that promote carbon sequestration in soil. Soil can store a lot of carbon and help reduce climate change. This storage capacity is crucial in the global effort to achieve carbon neutrality and limit the rise in global temperatures. To know how much carbon soil can store, it's important to study different land practices like planting trees, using crops as covers, and regenerative agriculture. By measuring and rewarding the carbon stored in soil, carbon credits encourage sustainable practices, resulting in improved soil health, enhanced biodiversity, and reduced greenhouse gas emissions. This synergy between soil and carbon credits offers a promising path to a more sustainable and climate-resistant future.

PRIMACS™ SNC-100 TOC TN analyzers

Skalar, a leading innovator in environmental analysis solutions, developed the PRIMACS™ SNC-100 analyzer to accurately determine the various carbon types in soil. This state-of-the-art instrument is specifically designed to quantify the concentrations of different carbon species: Total Carbon (TC), Total Elemental Carbon (TEC), Total Inorganic Carbon (TIC), and Total Organic Carbon (TOC). The instrument provides values for all three of these soil carbon species from a single soil sample, enabling researchers, scientists, and environmental professionals to gain valuable insights into overall soil carbon composition.

The PRIMACS™ SNC-100 uses high-temperature combustion to ensure all carbon is oxidized to CO2. In full accordance with DIN 19539, Its unique vertical sample introduction and precisely temperature-calibrated oven ensure that at a certain oven height, you have a certain temperature and therefore a certain type of carbon will combust. Those combustion products can be immediately quantified by Non Dispersive Infrared detection (NDIR). The temperature settings are user-definable in order to get optimum combustion conditions for different soil types.

This vertical injection mechanism has a second advantage as sample ash and residue remains in the crucible for easy removal post-analysis, thereby reducing maintenance needs. The PRIMACS™ SNC-100 integrated, 100-position sample rack and reusable ceramic crucibles facilitate large daily sample loads in a single batch, enhancing laboratory productivity. TIC can be separately analyzed through an automatic acidification and purging process and calculation of TOC as TC – IC = TOC becomes possible.

The PRIMACS™ SNC-100 comes with a flexible software package, including pre-installed method files, user-definable sample table setups and integrated QC features which further enhancing its usability and versatility for analytical laboratories.
