Sulfur Determination in Plant Tissue, Soils, and Fertilizers by Combustion Analysis

This webinar focuses on the importance of accurately measuring sulfur in fertilizers, plant tissues, and soils, and explains how combustion-based analysis supports better agricultural decision-making. It outlines why sulfur content matters across these matrices—from verifying fertilizer composition and supporting manufacturing quality control to diagnosing plant health issues and guiding soil management practices. The presentation walks through approved AOAC and ISO methods and highlights best practices for sample preparation, calibration, and low-level detection to ensure reliable, repeatable results across a wide range of sulfur concentrations.

The session also compares LECO’s 832 and 928 series analyzers, explaining how each platform handles sulfur determination and where their strengths apply. Viewers gain practical insight into instrument selection, method flexibility, handling challenging matrices like chlorine-containing fertilizers, and achieving accurate results on a dry-mass basis. Supported by real analytical data and case studies, the webinar demonstrates how these techniques deliver high precision and confidence for routine sulfur analysis in agricultural laboratories.
