A Comprehensive Look at Agricultural Analysis

From fertilizer to wastewater, what goes into soil is just as important as what grows out of it. In this webinar series, a group of experts from LECO will be discussing how LECO's state-of-the-art solutions can streamline your laboratory, leading to savings of both time and resources.

Whether considering changes to plant tissue or animal feeds, farm soil or wastewater treatments, LECO offers a diverse range of instruments to meet any growing need.

Each of the webinars outlined below offer insights into carbon, nitrogen, and sulfur determination, moisture, ash, and volatile matter analysis, and two-dimensional gas chromatography mass spectrometry (GCxGC) in various agricultural applications.

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

Presented by Jeffery Gast

Water content in soil and plant tissue is a key parameter that has an influence on crop yield and quality.

Key topics include:

  • How moisture plays a key role in the commerce and storage of food products.
  • Determination of ash content in soil to estimate the overall organic matter contained in the soil.
  • Review of 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

Sulfur is one of the most important macronutrients needed for plant growth, supporting the formation of amino acids and proteins, as well as chlorophyll formation.

Initiatives to limit sulfur emissions mean less sulfur is being deposited in soil, leading to an increase in the use of sulfur-containing fertilizers, which in turn increases the demand for sulfur determination in fertilizers, soils, and plant tissue.

This webinar covers a number of combustion-based approaches for sulfur determination.

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

Presented by Jeffery Gast

This presentation outlines TOC determination in soil via two different methods.

Gast will first explore the use of acid treatment of the soil to eliminate carbonates, followed by analysis using traditional combustion techniques.

Secondly, he will outline an investigation into the use of a ramped furnace temperature approach to distinguish organic and inorganic carbon species from one another.

TOC results from both methods will be presented.

Carbon and Nitrogen Determination in Soils, Plant Tissue, and Fertilizers by Combustion Analysis

Presented by Fred Schultz

Carbon and nitrogen are two main nutrients that are important to plant physiology. Carbon content in soil has a crucial role in plant growth and development.

Plant foods or fertilizers with that combine several plant nutrients often include nitrogen. The amount of nitrogen contained in fertilizer is usually optimized for the type of plant type being grown. The LECO 828 and 928 series of determinators can calculate the amount of carbon and nitrogen found in soils, fertilizers, and plants.

This webinar focuses on how to quantify 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

This presentation covers non-targeted GCxGC for environmental forensics, or exposomic analysis, of wastewater, specifically the semivolatile organic fraction, and what action to take if any non-targets identified could present health impacts.
