Sorry for the delay on getting the summary of grower meeting up on blog, we finished corn harvest on the weekend. The grower meeting was great lots of great topics and discussions. I wanted to get summarize the meeting for those who were not able to attend and refresh for those who did.
We first heard from Marla Riekman Land Specialist with MAFRI, she discussed more than just vertical tillage. Soil structure, soil compaction, residue management and vertical tillage. Marla made it clear all these things are related. My take aways from here presentation were 1) 80% of compaction is caused by the first tillage pass made, soil that is moist not saturated are most prone to compaction so in other words probably when we think its perfect time to till is perfect time to compact. The number one defense for compaction is soil structure. 2) Soil compaction can lead to many problems such as causes nutrient deficiencies, reduces crop productivity, restricts root development, reduces soil aeration, decreases soil available water, reduces infiltration rate, nutrient losses and increases surface runoff. 3) Vertical tillage does help with some compaction but only top 2-6 inches, vertical tillage can be useful in sizing residue, especially where crop type or weather conditions lead to slow decomposition. 4) When deciding whether a vertical tillage tool or which tillage tool is right for you make sure it fits the needs or expectations you want to achieve. 5) Good soil structure, reducing compaction and residue management will not occur over night there will be a transition period.
John Heard was next up and talked about soybean fertility and specifically phosphate. Soybeans roots do not react the same as many crops. While crops like wheat, corn and canola will concentrate in banded applied phosphate, soybeans are similar to flax, they will scavenge the soil for phosphate and grow past the banded fertilizer. Soybeans perform best in fertile soils and it is very tough to visually identify a phosphate deficiency so it is key to maintain adequate phosphate levels. Maintaining these levels can be done many ways, choose which option is best for your operation.
- Fall or spring banding
- Fall or spring broadcasting
- Some phosphate can be applied with seed but reduced plant population is a big risk
- Preloading crops in non soybean years, cereals can handle more phosphate in seed furrow that crop requires
One bushel of soybean removes between 0.8 to 1.1 lbs of phosphate from soil. So maintaining phosphate levels is not just important for soybean crop but also the following crop, its important to remember that only about 30% of spring applied phosphate with seed will be available to that years crop thus applied phosphate the year following likely will not correct any very low levels following soybeans. Also unlike some crops soybeans require the majority of their phosphate requirements later in the season and the majority ends up in seed which gets hauled to the elevator therefore removing it completely from the field. Potassium requirements are also large for soybeans and while our clay soils are for the most part high in K it should not be completely ignored. Key to understanding your nutrient requirements is regular and properly done soil testing.
Darcy Catellier talked about Lumiderm which is a new canola insecticide seed treatment it will extend flea beetle control up 35 days and is the only seed treatment to control cutworms. I know in the past few years canola fields in the area have been regularly sprayed for flea beetle control and cutworm control. If you have concerns for the upcoming growing year choosing Lumiderm treated canola seed may be an option for you. It is only available on selected hybrids and must be ordered by January.
We wrapped the meeting up with announcing that Dwight Willoughby has joined Derek Erb Seeds and we are extremely excited to have him, our key products and programs. 46H75 canola is a game changing and is gaining momentum across our area as one of the top hybrids to grow. The combination of DuPont Pioneer canola genetics and BASF’s new Clearfield chemistry make 46H75 a logical choice for canola growers especially if RR soybeans or corn are a part of your rotation. October 31st marks the end of our first discount period of 10% off for cash and 6% off for deferred pay.
So that was meeting in a nutshell, thanks for all who came and participated in the meeting.
