I guess nightshade doesn't get frost bite

The sight of nightshade's purplish/black berries in a "food grade" soybean crop is every producer's worst nightmare. They stain the seed and dramatically reduce the value of the crop. In theory, you would kill uncontrolled nightshade prior to harvest with either a herbicide (i.e. Reglone, glyphosate) or mother nature (i.e. a frost), the berries would drop to the ground, never go through the combine and the seed would be left unstained. Unfortunately this is a theory, and reality shows us… Continue

Field Bindweed Control in the Fall

Field bindweed is an aggressive perennial weed that reduces crop yield and slows harvesting speed especially in soybeans and cereals. Eradication is impossible, but minimizing its impact in field crops is possible with a management strategy that includes a fall application of glyphosate at 1.5 L/ac (360 g/L concentration). The photo below was taken in late May of 2004 and compares field bindweed populations in the untreated… Continue

I’m switching my wheat variety; do I need to change my seeding rate?

The short answer is yes; you will most likely need to change your seeding rate, but this is not just because you are planting a different wheat variety. Rather, seeding rates should be adjusted annually to reflect seed source characteristics (germination, thousand kernel weight [TKW]) and the environment the seed is being planted into, to ensure you can achieve your target plant population.   Let’s dig into why this is. For spring wheat, provincial target plant population recommendations are between 23-28 pl/ft2, with many producers targeting the upper end of this recommendation. Achieving your target plant stands sets your crops up for success, as crop uniformity is improved, weed pressure is combatted and resources are optimized.  Seeding rates should be calculated to achieve your target plant stand, which means accounting for germination percentage, expected mortality and, importantly, your TKW. TKW changes year-to-year and from variety to variety. Let’s consider an example to ill

How much 10-34-0 can be applied with my corn seed?

Oddly, I have had this conversation more this winter/spring than ever before. On paper, there is a finite answer. Anecdotally, there are a few different options and it is all dependent on soil type and soil conditions, moisture, etc. First of all, side-banding any type of fertilizer is much safer than placing it with the seed. Some fertilizers are safe in certain quantities with the seed, but very few. Side-banding is much safer and provides quick access to the roots. Midrow banding is the safest method, but roots take that much longer to access the fertilizer row, which negates the “starter” effect. The other factor that indicates the level of safety is soil moisture; the drier the soil, the more risky it is to place any fertilizer with or near the seed. I’m guilty of thinking that fertilizer toxicity to the seed is mainly due to the nitrogen content and a result of ammonia burn. Salt injury is actually more common and affects germination and early season growth, so applying fertili

Is Your Bull Ready? A Year-Round Approach to Bull Management

Every cow-calf producer has either lived it or knows someone who has. Breeding season wraps up and everything looks fine, until fall preg-checks tell a different story: open cows, late calvers and a breeding window that slipped wider than planned. While cow nutrition, body condition and management are frequently evaluated, one critical factor is often underestimated—the bull. Most frustrating is that there are often no obvious warning signs during breeding. The bull was turned out, was covering cows and looked the part. On the surface, everything appeared normal. That’s exactly why a bull breeding soundness evaluation (BBSE) matters more than many producers realize. It is one of the few opportunities to take some guesswork out of bull performance. On a cow-calf operation, bulls get a lot of attention for a couple of months out of the year and very little once breeding season wraps up. The reality is that a bull’s value doesn’t start on turnout day, and it definitely doesn’t end when
