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.

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.

How do you know what is in your food? If you're like most consumers, you take a look at the information on the back of your food packaging to know the ingredients and nutritional value. But how can you trust that information is correct? Where does that information come from? Someone like Jonathan Griffin, Public Analyst and Lead Analytical Services Manager at Kent Scientific Services in the UK, answers that question.

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 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.

In 2011, LECO's Cornerstone® brand software took the analytical world by storm. Intuitive screens. Adjustable charts. Diagnostics built into the software, with real-time monitoring and animated system diagrams. Designed by scientists, for scientists, Cornerstone blended industry-leading technology with practical functionality. Eleven years later, it's time for a facelift.

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.

Many LECO analytical instrument rely on consumables like pure chemical and high purity gases to function. When supply chain issues affect these consumables, laboratory operations can quickly increase in cost or in worst case scenarios can even be shut down. One current issue that is plaguing the scientific community is the supply of helium.

Alcohol is one of the oldest intentionally-crafted drinks in the world, with evidence of fermented drinks existing as early as 10,000 BC. It has remained an important cultural touchstone around the world, with most countries having some version of "going out for drinks" as a common social activity. While there are three main types of alcoholic beverages—wine, beer, and spirits—beer consistently remains the most popular alcoholic drink around the world and third most popular drink after water and tea. Recent Gallup polls find that 38% of Americans prefer beer to wine (30%) and spirits (29%).

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.
