Well-balanced crops require well-balanced soil. While carbon may be the most essential element for organic life, the right ratio of nitrogen and sulfur in the soil along with the carbon can really influence the speed and strength of plant development and growth. With a macro combustion carbon, nitrogen, and sulfur determinator such as LECO's CNS928, those ratios can be discovered easily through fast and precise analysis.
Working with grains meant a lot of thermogravimetric analyses, but standard oven drying methods were incredibly time-consuming. Depending on the flour matrix, oven times could range from 1 hour to 17. Whole grains could take a full 72 hours. LECO Africa reached out to Jolanda Nortjé, Laboratory Manager of The Southern African Grain Laboratory (SAGL), with a suggestion of a better way, and Nortjé was happy to give it a try. She agreed to participate in a comparison of a primary moisture loss-on-drying determination using the TGM800 and standard oven drying methods.
