Increasing research efforts at Calcium Products

In autumn of 2012, Craig Dick and I began discussing a Calcium Products research agronomist and manager of research & development (R&D). I was thrilled at the idea and gladly accepted the position a few months ago. I completed my Ph.D. at Iowa State University in May 2012 in horticulture, with a research specialization in turfgrass science. I know that may not equate into corn and soybean agronomy at first glance, but one of the purposes of obtaining a Ph.D. is to show you have learned how to subjectively think about problems and use the scientific method via research to answer them. Although my concentration was in the turf world, I have a well-rounded education that can be applied to any area of plant science. I started part-time with CPI in October while finishing my post-doc work at ISU and started full-time January 1. We have been busy exploring new…

Update from Iowa Soybean Association On-Farm Network on Sulfur

A few weeks ago, we had the pleasure of attending the Iowa Soybean Association’s On-Farm Network (OFN) conference in Ames. One of the highlights of the conference for me was the presentation by Dr. Tracy Blackmer about sulfur. Sulfur application over the past 30 years was generally considered non-essential due to the high levels found in our atmosphere from power plant emissions high in sulfur, thereby satisfying plant needs. Times and emission standards have changed and, as a result, sulfur levels are much lower in atmosphere and soil than they were in 80s and 90s. Dr. Blackmer observed sulfur deficient corn in recent years and even dug out some old photos during his time at the University of Nebraska that showed sulfur deficiencies—at the time unnoticed, which was very surprising to him. Perhaps we have negated the benefits of sulfur application for far too long! Gypsum (calcium sulfate) is a great source of sulfur…

Soil acidity

Within any given soil, there are two states of acidity that need to be accounted for before liming recommendations can be made. First is the active acidity, which indicates the current pH status of the soil. Active acidity accounts for the H+ ions in the soil/water solution that the laboratory measures. What active acidity doesn’t account for, however, is the reserve, or potential acidity. Think of a swimming pool that has a few people in it, those people represent the active acidity. Now, imagine that there are more people outside the pool, just waiting to jump in after some of the others leave. Those folks represent the potential acidity. When we determine how much lime we need to neutralize the acidity in the soil, it is really the potential acidity that needs to be accounted for. To neutralize the active acidity is easy and requires little lime, but the potential…

It has what plants crave...

Winter is a busy time for the sales staff at Calcium Products. We attend lots of meetings, conferences and events. Many times we get to share the stage with other manufacturers. Many of these companies will tell you the secret to why their product is so great is, “it's powered by (insert any nebulous word, scientific sounding description or acronym here)." They'll follow it with a strong pitch of "our results speak for themselves," and "trust us, it really works great, we know you’ll love it!" This is all well and good but if the sales person doesn’t understand the mode of action, physics and/or chemistry and biology behind their product, how do you, the agronomist or farmer, actually know it is a fit for your agronomic needs? Many of these pitches remind me of the 2006 movie “Idocracy.” The premise is an 'average Joe,' is frozen for 500 years and…
