Agricultural Analysis Webinar Series

From fertilizer to wastewater, what goes on your soil is just as important as what grows out of it. Join our group of experts as they discuss how LECO's innovative solutions streamline your lab, saving you time and resources. Whether you're looking at plant tissue or animal feeds, farm soil or wastewater treatments, LECO has a wide variety of instruments to meet your growing needs. Sign up today for any or all of these webinars to learn about carbon, nitrogen, and sulfur determination, moisture, ash, and volatile matter analysis, and two-dimensional gas chromatography mass spectrometry (GCxGC) in agricultural applications.

Thermogravimetric Determination of Moisture and Ash in Soils and Plant Tissue Materials

Presented by Jeffrey Gast | Watch recorded webinar

Water content in soil and plant tissue is an important parameter that can influence crop growth, yield, and quality. In addition, moisture plays an important role in commerce and storage of food products. Determination of ash in soil can be used to approximate the organic content of the soil. This webinar will review the Thermogravimetric determination of moisture and ash in soil and plant tissue.

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

Presented by Lloyd Allen | Watch recorded webinar

Sulfur is one of the essential macronutrients required for plant growth, aiding the formation of amino acids and proteins, as well as chlorophyll formation. Initiatives to reduce sulfur emissions have led to less sulfur being deposited in soil, causing an increased use of sulfur-containing fertilizers; resulting in an increased demand for sulfur determination in fertilizers, soils and plant tissue. This webinar will outline several combustion based approaches for sulfur determination in these materials.

Total Organic Carbon (TOC) Determination in Soil Using Acid Treatment and Temperature Differentiation

Presented by Jeffery Gast | Watch recorded webinar

The presentation will outline TOC determination in soil using two different approaches. First, we will explore the use of acid treatment of the soil to remove carbonates followed by analysis using conventional combustion techniques. Next, we will explore using a ramped furnace temperature approach to differentiate organic and inorganic carbon species. TOC results from both approaches will be presented.

| Presented by Fred Schultz | Watch recorded webinar

Carbon and nitrogen are two of the primary nutrients of vital importance to the physiology of plants. Carbon content in soil plays in important role in the growth and development of plants. Plant foods or fertilizers with blends of multiple plant nutrients often including nitrogen. The amount of nitrogen in the fertilizer is optimized for the plant type that is being grown. The LECO 828 and 928 series of determinators can quantify the amount of carbon and nitrogen in soils, fertilizers, and plants. This webinar will focus on quantifying both carbon and nitrogen in these matrices.

Environmental Forensic Investigation of Wastewater Applied to Agricultural Fields - What Do We Not Know, and How Do We Find It?

| Presented by Frank L. Dorman, Penn State University Dept of Biochemistry and Molecular Biology & Dartmouth College Dept of Chemistry |

How do we find what we don't specifically look for? This presentation will look at non-target GCxGC for environmental forensics, or exposomic analysis, of wastewater, specifically the semivolatile organic fraction, and what can be done when discovered non-targets may present health impacts.
