Corn Crop 2011

There is a lot of apprehension in the upper Midwest about the condition & size of the 2011 corn crop.  Many dealers & farmers have shared concerns that the yields will not match up with what we have come to expect, or with the market demands.

Why not?  Many factors, including:

  • Delays in getting the crop planted in many areas
  • Slow growth & development due to cool growing conditions
  • Significant flooding along the Mississippi & Missouri river corridors, and their tributaries
  • Very warm conditions during the critical month of July.  Pollination & grain fill typically happens in July
  • Drought in Texas, Oklahoma, Kansas & the southern Plains.  This has moved east & north into Illinois, Indiana & Ohio recently
  • Summer storms with high wind & hail.  I have heard of at least several hundred acres in IA & NE that were destroyed by a storm last night.

The beef industry is already preparing itself for smaller corn supplies.  Will cattle feeders use less corn in the future?  Here's 1 opinion:

SuperCal Helps Pay the Bills In Canada

Last week I went to Stettler, Alberta in Canada to tour some test trials of SuperCal products.
Our newest dealer McRae Holdings, put out lots of trials on wheat, barley, and canola. While it's still too early for yield results, there were some definate visual advantantages.
The soils near Stettler are 4-8% organic matter and mostly 20% calcium. Application of only 100 lbs of SuperCal SO4 have increased root penetration by 1 inch. In these low calcium heavy tight soils you normaly can only sink a shovel a couple of inches into the soil. So adding 200 lbs on SuperCal SO4 effecitvely doubles the rooting depth! In additions to the big gains they are seeing from SuperCal 98G and SuperCal SO4, Boron and Copper have show a big response as well.
If your looking to increase yields in western Canada, we highly recommend McRae Holdings.

Differences Between Lime & Gypsum

Lime & gypsum-Aren’t they the same?
Educating farmers about pH, sulfur, calcium, lime & gypsum is a big part of what I do.  There exists a considerable amount of people who believe that lime & gypsum can be interchanged for each other.  Occasionally, this even occurs at the dealer level.  A quick overview of each:
Lime, or calcium carbonate (CaCO3), is the naturally occurring mineral used to improve an acid soil.  When the soil pH is less than 7, acidity exists as an accumulation of hydrogen (H), and aluminum (Al).  Aluminum, which is toxic to plant growth, is soluble when the soil pH is less 5.5.  When hydrogen accumulates on the outside of a soil particle, or exchange site, their presence is measured by a pH test.
When lime is applied to an acid soil, the carbonate molecule (from lime) & hydrogen combine.  The end products from this reaction are H2O (water) & CO2 (carbon dioxide).  Calcium is now attached to the exchange site.  Because the carbonate liberates the hydrogen, the soil pH will improve (become less acidic).
Gypsum, or calcium sulfate (CaSO4), is a naturally occurring mineral.  It provides calcium & sulfur, both essential nutrients, but does not affect soil pH. It is a neutral salt (pH is ~6.7) & has a salt index, or osmotic potential, of 8.  It typically has 20-22% calcium, & 16-18% sulfur.  The sulfur is in a plant available, or sulfate (SO4) form.  In addition to providing needed nutrients, the calcium in gypsum is soluble, even at a pH that is >7.  This can be very helpful in improving soil tilth, reducing soil compaction, & improving aeration.
Do you need lime, gypsum or both?  We will continue this discussion in a future blog.
