Walking Fields

It was a chilly field walking morning, but this is an important job for our farm!

This time of year as things start to really grow and plants start to set the crop for the upcoming summer harvest, we have to take time to walk all our fields and look for issues.

“Issues” right now in this growing stage usually means weeds. We are currently spraying our final (hopefully) application of weed spray. We use chemicals that are selective so they only target weeds that we see out in the field. It’s a great way to save money for us and save on putting more chemical where it’s not needed. For example we have a few fields that have a lot of groundsel, we will add an additional weed herbicide in to manage that so it doesn’t show up as a weed in our seed tests at the final stages of getting clean crops to sell. Also hoping that it doesn’t show up again next year as a continual problem.

Our weed spray is mixed with a carrier of fertilizer and water; which in turn saves us an application across the field to get our final amount of nitrogen to feed the crop. This efficiency increase saves us time, money, and fuel. But in order to makes this all happen we do have to walk around every single field to see what is out there.

This is a nice clean area of a tall fescue field.

Our farm works alongside field men who work for companies where we buy our fertilizer and chemicals. More boots on the ground means that we have a very good chance of not missing something. And if we do our jobs well; setting ourselves up to have clean seed fields that create a valuable product for us to sell.

Weed Spraying by Backpack – It’s Not Efficient, But It’s Important

A common theme on this blog has been that farmers always try to do more with less; which is just another way of saying that in most ways possible we try to be as efficient as possible. That can be quantified in time, labor, use of tools such as chemicals, water management, etc. All of it comes down to doing more with less. But sometimes there are jobs on the farm that are really inefficient by nature and…they are really annoying.

One in particular is one that we do almost every spring, spraying some of the very hard to kill weeds that we have around our farm, sometimes in the field and sometimes on the headland of our fields. Three that quickly come to mind and are on my radar today are blackberries, wild carrots and Canadian thistle.

Blackberries growing along one of our orchards and the roadway.

There seems to be a well accepted myth that pesticides including herbicides kill all living things, in truth that just isn’t the case. When managing weeds in and around our fields we have to take into account the growth stage of the weed, the timing of the year, the temperature of the air, and choice of herbicides, what is labeled, and rates on the label. Also will the herbicide kill it? Will it suppress it? Will it just hold us over until something better can be used at another time of year?

The timing windows on herbicides and weed control are very important. A good example of this is that until a few years ago we didn’t have good control of blackberries in the spring when they are actively growing and starting to take over. We were not able to spray crossbow because it can easily volatilize with the heat this time of year and hurt the surrounding plants, which is not a good thing. Now we have an herbicide that is safe to use even when it gets into warmer temperatures during the spring. Adding a completely new timing window to safely and effectively control blackberries. Unfortunately however, that tool doesn’t kill or control thistles or wild carrots.

Here is a prime example of an area on the edge of one of our fields that has all three weed issues.

And here is where we hit this whole efficiency problem. Today I’m out spraying with a backpack along our borders. I’m getting areas that have blackberries first with my backpack filled with a mix of PastureGard. I’ll come back later with another backpack mixed to control thistles. And then for third time, rinse and repeat, with a backpack to kill the wild carrots.

This job is annoying because it takes 1000 years to do. But it’s also very important to keep weeds suppressed before they become an issue in the actual crop land and can quickly become a much larger, and a much bigger efficiency problem than just me with a backpack. So one could argue that by doing this annoying job, I’m actually making things more efficient for the future….I mean it doesn’t feel like that to me, but one could argue.

Oregon Grass Seed Research Roundtable

I often think in the back of my head that as farmers we really are never doing things the way that we have always done them, mostly because I’m constantly reminded when I talk to non-farmers that is what they assume. I’ve written before about how farmers are always “Doing what we’ve always done – NOPE!”. Last week I had the privilege of attending a grass seed research roundtable at Oregon State University. This is the first year that one has been held here in Oregon specific to grass seed. The room was full with over 30 stakeholders and another dozen or so logged in through zoom. Another reminder to me about how forward thinking and solution oriented this industry here in Oregon continues to be; which I love!

If we’re honest I think we can agree that research isn’t the most riveting topic most time, but the set up of this roundtable allowed us all to hear a summary from the researchers, limited to 10 minutes; enough time to summarize but not get too deep in the weeds of research which can put even the most nerdy farmer asleep (no offense to those in research). Which was followed up by 5 minutes for questions from producers, seed dealers, field-men, and other researchers.

Topics included many of the pests that we are constantly battling in the field and other challenges that we face as producers and as an industry as a whole. Voles, billbugs, symphylans (research to help off set the gap in control that the Lorsban/chlorpyrifos ban left us with), DNA testing for seed, field residue and pre-emergent sprays, optical seed sorting, weed management and smart sprayers, crop stand longevity, straw management and what that means for our soil and carbon sequestration, nitrogen leaching potential, and on and on.

They say that the definition of insanity is doing the same thing over and over again and expecting a different result. It’s no different in the farming world. Sitting there last week was a continuous reminder that our industry is always changing, adapting and finding solutions. As a solution oriented person both in my personal life and in my farming life, this was all very exciting to me.

Now comes the tough part of ranking them all for funding; research doesn’t come free but the knowledge that we will gain from these trials will pay time and time again for this industry here in Oregon. Last week was just another reason I’m proud to be a grass seed producer here in Oregon.
