Choosing the right rate of nitrogen for a corn crop can be tricky: the soil will mineralize some, the fertilizer will provide some, and biological sources, such as manure, will offer some N as well. What tools exist to help choose the right rate, and should an N addition be protected? On this episode of... Read More

We've made it to 200 episodes! On this special episode of The Agronomists, host Lyndsey Smith is joined by Deb Campbell of Agronomy Advantage and Pierre Migner of Agro 100 to discuss the difference between biotic and abiotic stress on plants, what does and doesn't help plants manage different stressors, and planning for direct support...

There are literally thousands of insects currently humming or crawling about in grain and hay fields, shelterbelts, and riparian areas. Yes, some are pests of crops and livestock, but many, many more of them are beneficial insects. Beneficial insects aren't just pollinators either: some are voracious eaters of weeds or weed seeds, some attack and... Read More

The easiest and most effective way that plants take up nutrients is through roots; however, nutrients in the soil can be positionally unavailable, deficient, or tied up. When that happens, foliar applications of some nutrients can be beneficial, but not all nutrients and not all the time. To delve further into foliar feeding, this episode... Read More

It can be rather tempting to throw in one or two extra things in the spray tank when it's time for a pass — time and fuel is precious, after all. But depending on several factors, adding another product or nutrient to the tank can end up costing way more time in sprayer clean-out if... Read More

An ideal canola stand starts with a dialled-in seeding rate, known seed survival rates, a steady seeding pass, and protection from pests. Putting all the pieces together requires making key decisions at each point in the process. For this episode of The Agronomists, host Lyndsey Smith is joined by Chris Manchur of the Canola Council...

A plant growth regulator (PGR) can strengthen and sometimes shorten cereal stems, reducing the lodging risk and increasing harvest efficiency, but not every field is a candidate for a PGR application. To navigate the why and when of PGR passes, this episode of The Agronomists features Sheri Strydhorst with RDAR and Marijke Vanderlaan of Syngenta.... Read More

From hoses and wiring, to metering and closing wheels, there's no shortage of system checks pre-seeding or planting. But there's more to do than just check for wear and tear, as leveling and dialing in seeding rates are critical for this most important pass. On this episode of The Agronomists, host Lyndsey Smith is joined... Read More

Cover crops can keep soil and nutrients in place, suppress weeds, and fix nitrogen, but they can also use too much water or create a mess of rotting plant material if not terminated properly. On this episode of The Agronomists, host Lyndsey Smith is joined by Kevin Elmy with Cover Crops Canada, Jim McComb with... Read More

When it comes to applying herbicides, is it better to do an imperfect job at the right time or a perfect job at the wrong time? This isn't a philosophical question, but it does require some discussion to fully understand what goes in to a spray pass to ensure that it's worth the cost of... Read More

Phosphorus plays a critical role in early seedling development and is needed throughout the growing season to achieve top yields. Phosphorus is also not mobile in the soil, as it gets held tightly to soil particles. Roots do their best to seek out and mineralize phosphorus, but managing P requires long-term planning. To dive in... Read More

More than just spell check and generating quirky images, artificial intelligence already plays a role in several aspects of our daily lives and agriculture platforms and technology. But what can AI do now and what role might it play going forward? To delve into the mash up of AI and agronomy, this episode of The... Read More

Much of the focus of soil conservation practices emphasize decreasing the movement of soil by wind and water erosion. These forms of soil movement are costly from a soil health, farm productivity, and environmental standpoint, however they are not the largest erosion risk to a field. That honour belongs to tillage erosion — the act... Read More

It's the very last episode of The Agronomists for the 2024 season and host Lyndsey Smith is joined by Peter "Wheat Pete" Johnson and Ray Dowbenko to discuss the top agronomy stories of the year! On this episode, the trio talk about: Current and future uses of spraying technology in farming production; The mysterious but... Read More

Pulses, such as peas, lentils, chickpeas, and faba beans, can be an excellent addition to a crop rotation as they fix their own nitrogen and even leave some for the next crop. The crops do have serious challenges, however, including aggressive root rots and diseases that can decimate yields, especially in wetter years. To unpack... Read More

Multi-herbicide resistant weeds have been found in several Canadian and U.S. regions and the amount of ground they cover expands every year. On the list of worst offenders: kochia, wild oats, waterhemp, and Canada fleabane. Herbicides will continue to play a dominant role in weed control, but which herbicides, what type, and when is a...

Being an agronomist means knowing about plants, diseases, soil, and insects, but it also requires the ability to navigate difficult conversations, earn trust, and drive change. The people part of the agronomy equation is the topic of this episode of The Agronomists. Here to talk about personality differences, clear communication, and patience with people is... Read More

One of the most powerful and inexpensive tools farmers have in the pest management toolbox is crop rotation. A well-planned rotation can add yield stability, more yield, decreased weed and insect pressure, and keep diseases in check. The question is, how do we know which crops should be in a rotation and what benefits we... Read More

Not all datasets are created equal. Without a check strip or variety to compare to, or if too complicated, or with too few replications, resulting trial numbers can be nearly meaningless when comparing one decision to another. Good data means that farmers and agronomists can choose a practice or change or hybrid with a level... Read More

There’s never a shortage of field work to be done in the fall, but fall conditions can sometimes be very unfavourable for tillage, manure, or fertilizer applications. To dig into considerations for fall field work, including compaction, nutrient losses, and cover crop success, host Lyndsey Smith is joined by Curtis Cavers of AAFC, Glen Arnold… Read More

You can’t manage what you don’t measure, and if you’re not measuring grain loss out the back of the combine, you could be losing two, four and even 10 bushels an acre on the harvest pass. Recognizing that both header loss and combine loss contribute to lower yield and volunteer issues for the next season,… Read More

Determining sulphur application rates ahead of the crop can be complicated by several factors, including how much sulphur the environment will provide, if elemental forms of sulphur have been applied in the past, and how much rainfall is expected. Sulphur is an important macronutrient that’s also prone to leaching losses and not mobile in the… Read More

Sure, yield matters, but there’s more to making yield than just genetic potential, including disease resistance and adaptation. Choosing a soybean variety or canola hybrid requires balancing several demands based on a geographic area, yield potential, management options, and disease pressure. To navigate the decision, this episode of the Agronomists features Allison Bishop with BASF,… Read More
