Soils TOC: Analyzing Acid-Treated Samples is Now Easy as ABC

February 12, 2024

As the concern for global warming has increased over the years, ways to sequester carbon has been top-of-mind for many scientists and researchers. Capturing atmospheric carbon in the form of carbon dioxide, converting it, and storing it in soil would not only help the overall environment, but it could help farmers grow better crops as well.

Growing Hope: A Convoy of Hope Update

July 7, 2023

According to Dr. Jason Streubel, Senior Director of the Center for Agriculture & Food Security for the Convoy of Hope, hope comes from being able to feed yourself, your family, and your community. Hope comes from the security of knowing where your next meal is coming from and the ability to turn your focus to the future instead of the immediate present. Hope comes from agriculture.

Scorched Soils: Determining Moisture Content with the TGM800 and TGA801

June 16, 2023

Moisture levels in soil are important to know when growing plants. In addition to being a necessary component of photosynthesis, the moisture in soil acts as a carrier for a plant's essential nutrients, such as nitrogen and carbon. Knowing the moisture content of your soil enables you to properly balance the nutrient density and correct for moisture issues. Traditional manual drying methods have been lab-tried and -tested, but they can feel like relics of the past as today's lab is tasked to do more with less time.

Guaranteed Analysis: Moisture and Ash

May 26, 2023

Unlike the detailed list of nutritional requirements for human food, pet food in North America must only report on four main values in their Guaranteed Analysis on the label: protein, fat, fiber, and moisture. Additional nutrients must be included if they are called out specifically on the label, but manufacturers can also voluntarily add more nutrients to provide consumers with more information or further demonstrate the nutritional value of their products. Surprisingly, one such voluntary "nutrient" that frequently appears on labels is "ash."  However, the presence of ash in the Guaranteed Analysis does not indicate the presence of literal ash in the food; instead, it explains the process through which the mineral content is determined.

Kjeldahl vs Dumas: Determining Protein

May 5, 2023

Ever since its development in 1883, the Kjeldahl method of protein determination had been the standard in laboratories across the world. It wasn't until the 1990s that the Dumas method began acquiring a foothold. Though the Dumas method was technically older than the Kjeldahl, only recent technological developments have made it easily accessible to labs, and "easily accessible" is certainly one way to describe the modern Dumas method of protein determination, especially how LECO does it.

Spring has Sprung: Fatigue Fracture Surface Evaluation by Optical Microscopy

April 21, 2023

Most fasteners are essentially springs, and when these fasteners fail it is usually abrupt, "out of nowhere," and caused by fatigue. Fatigue failure is estimated to account for 80-90% of all fastener breaks. However, by its very definition, fatigue damage happens over time, due to repeated loading that stresses an already weakened location. ASTM E1823-10a, Terminology Relating to Fatigue and Fracture Testing, defines fatigue as: "The process of progressive localized permanent structural change occurring in a material subjected to conditions that produce fluctuating stresses and strains at some point or points and that may culminate in cracks or complete fracture after a sufficient number of fluctuations." Preventing fatigue failure is a critical part of engineering designs.

Plant-Based Protein for the People

April 14, 2023

While plant-based proteins have been part of humanity's diet for centuries, it wasn't until the advent of the original textured vegetable protein (TVP) in the 1960s that it started becoming a viable replacement for animal-based protein sources in more mainstream diets. The first commercially available plant-based proteins would not be mistaken for animal-based protein sources and were largely of interest only to vegans, vegetarians, and pescatarians. 

Things have changed dramatically in the plant-based protein sector, especially in the last ten years. Meat-substitutes that looked, smelled, felt, and tasted similar to meat swept the market, and in an age where consumers are becoming more and more informed and interested in sustainability and stewardship of the planet, plant-based protein has risen as a viable alternative for about one in four consumers, those who consider themselves flexitarians.

Soil Moisture Measurements with the TGM800

April 4, 2023

Soil moisture is a strong indicator of the health and potential of soils in a field, but there is no set value that means soil is "good." The makeup of soil is just as important as the types of plants attempting to grow in said soil to know what levels of soil moisture are optimal for any given situation. Furthermore, nature has a nasty tendency to throw a curveball, knocking carefully balanced irrigation plans out of whack.

Sports Development Starts in the Lab

March 31, 2023

When you think of a sports competition, you may picture several athletes at the tops of their game duking it out for supremacy, whether on a pitch, a track, a course, a pool, or wherever else their sport takes them. But sport competitions can transcend humans challenging each other. The competition in the sports equipment industry is just as fierce as that between players.

Determining the Strength of Coal

March 3, 2023

It remains impossible to predict the future accurately, no matter how much we try. While market forecasts and trends tend to illustrate the future of products, reality always has a chance to throw a curveball. Between the global COVID-19 lockdowns suppressing most markets and a trend toward renewable energy sources, coal was expected to start decreasing in market value. Instead, a war between Russia and Ukraine and the lifting of lockdowns has actually driven a higher demand.
