On Monday I attended a meeting put on by International Ag Labs titled Soybean Summit - Pushing the Yields on Soybeans, in Fairmont, Minnesota.
I number of experienced agronomists spoke on many items. Here are some of the notes I took;
- Drying soil when doing a lab analysis increases sulfur readings
- Greatest soil S loss when K and Na are high
- Stunted plants and uneven crop emergence can be caused by sulfur deficiency
- 2010 should be a bad white mold year for soybeans
- Sencor can worsen white mold
- If your roots are not bright white you do not have enough available calcium
- May take 3 years to improve soils
- P:K ratio of 1:1 for proper growth and to reduce weeds
To Control Insects:
- Control Nitrate levels in the plant
- Keep plant Sugar high
- Keep available calcium high
- Use the right form of phosphate for your soil
For Higher Yields on Beans
- Break Compaction
- Get oxygen into the soil
- Lime or Gypsum and apply manure
- Meet early needs of the plant
- Identify diseases and insect problems
- Foliar Feed
And what you been waiting for my notes from Kip's talk (In my words)
- Crops should ripen with a green stalk, if not your not fertilizing properly
- Accurate planting is key, drills do not do this
- All seed emerging within 48 hour of the first plant
- 2" tall weeds remove 10% of yield that cannot be recovered
There was much more discussed but my key take-away was fertilize properly first, get your soil balanced and working then move on to other things. This was a great meeting for any farmer looking to improve yields. I highly suggest trying to make it to one of International Ag labs next meetings.
