The Total Nutrient Digest (TND) analysis accounts for all minerals from sand, silt, clay and organic minerals in the soil. This total represents the plant available and non-available mineral nutrients. The textbook definition of a soil is that there is about 45% mineral content. Therefore, about 750 tons of all different minerals. The TND analysis […]
Recently, I had a horse owner question the quality of their hay because some bales appeared greener than others and some appeared to be less ‘stemmy’ than others. They submitted three samples from three different bales to run hay analysis for horses. The samples were identified as brown, green and fine. It was interesting to […]
Over the past year, our soil experts have added the Soil Health Assessment test. Soil health is the overlapping areas of the chemical, physical and biological properties of the soil. Previously, the chemical or nutrient status of the soil has been the main focus of soil testing laboratories. Recent addition of biological properties have become […]
Winter Fertilizer Application During my winter travels with Ward Laboratories, I frequently observe dry fertilizer application on frozen ground. This is generally an ill-advised practice. In Nebraska, the “Bomb Cyclone” event of March 2019 is a well-documented example of why we advise to avoid amendment application on frozen or snow-covered ground. In this event, large […]
As a consultant in central Nebraska, one of the most common questions I receive is: “Have DDGS changed?” Of course, there is lots of antidotal evidence that ethanol plants are getting more efficient. Plants have improved utilizing all the starch from the corn and removing more of the corn oil. Let’s review the ethanol production […]
Ward Laboratories has been performing stalk nitrate testing since 1990. This test can be utilized to evaluate the efficiency of your in-season nitrogen program for corn and sorghum. A stalk nitrate analysis is to be used only for agronomic management. When evaluating nitrogen use efficiency, we specifically check a lower portion of the stalk for […]
For successful soil sampling, you must submit a quality sample into the lab. Below are some points to consider before heading out to soil sample. Choosing a Soil Probe Soil probes are available with 12-inch or 18-inch buckets. If you will be sampling in heavy clay soil, a 12-inch probe is recommended as sampling in […]
It was just a little over a year ago that Chuck Powell, a goatpacker from California called our lab regarding his packgoats and urinary calculi. He was reaching out in a last-ditch effort to determine what was going on with his goats. To determine why they were developing urinary calculi. Mr. Powell had already lost […]
As a consultant at a commercial testing laboratory, “Why is my RFV and RFQ different?” is one of the most common questions I receive from producers looking at their forage report. Most often, the question is posed when there is a major difference between the relative feed value (RFV) and relative forage quality (RFQ). The […]
We often get the chance to listen to hear Dr. Ray Ward speak about soils, we seldom get to hear Dr. Ray Ward’s Business Advice. However, Dr. Ward was invited to speak on a panel, Big Businesses Start Out Small, at the 2022 MarkeTech conference here in Kearney. The moderator stumbled over Dr. Ward’s bio […]
We have added industry-leading soil microbiome testing to our robust agricultural testing product offerings! Ward Laboratories, Inc. already offers soil health assays including: Soil Health Assessment Phospholipid Fatty Acid (PLFA) analysis Water holding capacity Enzymes Wet Aggregate Stability Similarly, through our partnership with Trace Genomics we offer soil microbiome analysis. This analysis allows our customers […]
Irrigation water analysis might not be top of mind when thinking about crop fertility, but it is a critical piece. Consider that the minerals in the water end up on the field. This can mean less fertilizer is needed. Conversely, it can mean there is a need for additional applications on dry land. So, let’s […]
Often, we struggle to find forage in a drought. In Nebraska, the effects of the drought are prevalent. We have seen no April showers, instead wind and grass fires. These conditions are forecast to persist. So we are going to need to start making our forage plans early. Additionally, we will have to rely more […]
Being aware of the potential risks of heavy metals in soils is important. In Omaha, 125 years of lead smelting at the American Smelting and Refining Company (ASARCO) resulted in elevated soil lead concentrations (around 400 ppm) near residential housing. Furthermore, a study conducted on an urban garden soil near a railroad station in Lincoln […]
In 2017, in an effort to support my own continuing education, I attended the first mineral nutrition for beef cows program. The very first program was an all day meeting hosted by Adele Harty of SDSU Extension at the Cottonwood Range and Livestock Field Station. The day was packed with an abundance of information. Subsequently, […]
The ultimate question of why Ward Laboratories, INC. has a feed department: Why test feeds? Approximately 2 years ago, in 2020 I tried to answer this question in blog post: Value in feed testing: feed analysis pays off in profits. Here we are 2 years later with drought conditions persisting across western United States. These […]
For many cattle producers, it is a relief to put the cows to pasture. We have just overcome winter feeding obstacles, and many of us are ready to turn the cows out and focus on other tasks. However, are you certain they are receiving the nutrients required to support their calf? Lactation is a demanding […]
When we make fertilizer recommendations for upcoming crops, it’s good to consider nitrogen credits from past crops. Leguminous species like soybean, alfalfa, and clover may provide a nitrogen credit for the next season’s crop. However, there are a few misconceptions about where the nitrogen credit comes from. Soybean Nitrogen Credits For this example, we’ll talk […]
Recently, I have consulted with packgoat hobbyist and livestock producers to interpret their livestock water suitability report. Because water is a vital nutrient, understanding these reports is very important to make good decisions. Water plays an important role and many biological functions including transportation of essential nutrients to body tissues and cells, lubricant for the […]
Ward Laboratories uses soil test methods developed and calibrated by land grant universities. Standard methods are published in several manuals. We prefer to use standard methods that have performed well for many years. Soil pH & EC: We use a 1:1 water pH. This means we measure 10 grams of soil and 10 mL of […]
