Biomass to Markets: Determining Value

January 20, 2023

As global industrialization has increased, so too has global waste. Over 2.6 trillion pounds of waste are generated worldwide each year. Energy demands continue to grow year over year, and the Earth's population is looking toward greener solutions. Those 2.6 trillion pounds of trash may be waste now, but some of it may be suitable as biomass.

Old Traditions for a New Year

December 30, 2022

There is something satisfying about watching all of the numbers on the clock and the calendar roll over to a fresh start in a new year, and that sense of a fresh start and a chance to begin anew is celebrated the entire world over. Many of these celebrations include hopes and wishes for luck, fortune, and longevity and are underlined by offerings of food and drink. After all, you should always start a new year in the way you hope it to continue!

Dairy Determination with the FP928

December 9, 2022

Got milk? The infamous advertising campaign started in 1993 for the California Milk Processor Board and was an instant success. The strength of the advertisements stays true even today, with 90% of all Americans aware of the slogan. Though the campaign has been retired in all but California these days, the dairy industry is continuing to grow around the world. A huge part of this forecasted growth comes from the growing interest in dairy protein.

Fields of Fortune: Analyzing Crops with the 828 and 928 Series

November 18, 2022

Farmers are fortune tellers. In so many ways, they must predict what will happen in the future. What seed do they plant? How many? Will there be a drought? What will their yields be? What will the market be like? Everything science can do to give farmers an edge in their predictions can help make their futures more secure. One such advantage arises from carbon and nitrogen determination in soil, fertilizer, and plant tissue.

Total Organic Carbon with Two Methods

October 21, 2022

Carbon is an essential building block of life on our planet. The amount of carbon present is an important factor in soils and agriculture. Carbon levels can help determine the quality of soil or the location of natural hydrocarbon fossil fuel deposits that may affect the quality of raw building materials. These levels can be determined by a Total Organic Carbon (TOC) determination. LECO's line of instruments includes several that can determine TOC in different ways.

Hope for the Future: A Measured Science Podcast

September 23, 2022

Where does hope come from? For 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.

Sulfur in the Fields: S832 and CNS928

August 26, 2022

Sulfur is an essential nutrient in crop production. It is vital for the production of chlorophyll and several amino acids that form protein, among other functions in plants. In recent years, the world has been paying more attention to sulfur emissions, trying to minimize SO2 in the air, which in turn minimizes the sulfur deposited naturally in the fields. When combined with the trend toward high-yield crop production in many areas of the world, knowing the actual level of sulfur in your fields has become even more important. Sulfur can also be measured in plant tissues, and then, of course, knowing the sulfur content of fertilizer is also necessary to correct any sulfur deficiencies or excess in your fields. All of these sulfur determinations can be handled with a single combustion instrument from LECO.

Scorched Soils: Determining Moisture Content with the TGM800 and TGA801

August 5, 2022

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.

Kjeldahl vs Dumas: Modern Protein Analysis

June 3, 2022

Since the 1800s, there have been two major methods of protein determination, the Kjeldahl and the Dumas methods. Both methods measure the nitrogen in a sample and use mathematics to convert that into the protein content. Though the Dumas method was older, the Kjeldahl method quickly took off in popularity due to its relative ease of performance. However, as new technologies developed, the Dumas method began gaining in popularity.

We Don't Know What We Don't Know (But GCxGC Can Find It)

May 27, 2022

LECO recently concluded a webinar series on agricultural applications of our instruments with a presentation by Dr Frank Dorman of Dartmouth College, Department of Chemistry, formerly of Penn State University, Department of Biochemistry and Molecular Biology. While at Penn State, Frank worked on an environmental forensic investigation of wastewater applied to agricultural fields.
