398 - Fine Tuning 2001 Plans
There is still time for shareholders to make last minute adjustments to crop management plans.
Thoroughly review each step of the beet production system. Timely implementation of every aspect of raising a crop is key to achieving maximum yield, quality, and revenue per acre.
Q. October rains prevented fall nitrogen fertilizer applications, what are my spring options?
A. Broadcast apply spring N at no more than 60-70 lbs./acre. Higher rates may reduce stand establishment. Sidedress with broadcast urea if additional N is needed when beets are in the 2-6-leaf stage.
Q. If planting is delayed can I reduce my nitrogen fertilizer application?
A. If planting after May 7th reduce nitrogen applied by 10 lbs./acre for each week planting is delayed to maintain crop quality.
Q. How much should N be reduced to take advantage of the prepile payment system?
A. Consider reducing available nitrogen on headlands to a total of no more than 70-80 lbs./acre of soil test N plus added fertilizer.
Q. What other headland management practices might help maximize revenue per acre during the prepile harvest period?
A. Several practices may be beneficial and should be evaluated:
- Plant a high sugar/ton variety
- Maintain plant populations at not less than 160 beet/100’ of row
- Plant headlands to another crop
- Manage a whole field just for the prepile lift
Q. Can I successfully produce sugarbeets following soybean in rotation?
A. Grower practice records from American Crystal, Southern Minnesota, and Minn-Dak indicate yields following soybean versus corn or small grains are almost always about 1,000 lb./acre lower in recoverable sugar. NDSU/U of Mn research trials show almost identical results.
Q. Is it to late to utilize satellite images of fields to save $10-15/acre in nitrogen fertilizer costs yet this spring?
A. No, contact your agriculturist for assistance with imagery interpretation, an economics analysis of cost savings, and getting variable rate spread maps. It only takes a couple of hours to do this.
Q. Will using only a starter fertilizer for crop phosphorus needs deplete soil P, lower soil test P levels, and effect yield and quality?
A. American Crystal, NDSU, and U of MN agronomists agree there should be little effect if any on P soil test levels or yield and quality for many years. Remember broadcast P applications will still be made on other crops in rotation.
Q. Which herbicides contribute to the resistant kochia problem in crop rotations?
A. The following ALS enzyme inhibitor products listed in the 2001 ND Weed Control Guide all have the same mode of action that Kochia is resistant to.

Extract and Analyze Your Field Image
In the last issue of Ag Notes we stepped through getting the desired image of the selected field and year on the screen. When you have that up on your screen, click on the extract button in step 4. A file download screen will pop up in your screen. It will ask you if you want to open the file in its present location or save this file to disk. Choose “save this file to disk” by clicking in the white circle beside it and then clicking on the “OK” button. Now a save as screen will pop up. Choose a name for your file and choose “all” document types. Then click on save and the file will be downloaded into your chosen location.
If you do not have a recent copy of the viewer you must do two things: First, erase all old viewers in your system and then download the viewer by clicking the “download viewer.” A file download screen will pop up in your screen. Click on the white circle beside “save this program to disk” and then click “OK.” Next a save as screen will pop up. Choose the path where you want to save the viewer then click on save. A download complete screen will pop up. Now click on the open button. You are now ready analyze your downloaded file with the viewer.
Now the viewer is on your screen. Click anywhere in the viewer to remove the logo block. Then click on file and then open and then the file name of your extracted field. The field will pop into the viewer. Up on the toolbar, the second button from the right is a darkened rectangle with a dotted line around it. The “select all” button. Click on that button to select your whole field. The fifth button from the right on the toolbar contains a small-darkened rectangle with three arrows coming from it. This is the “zoom to fit” button. Click on that button. Your field will now fill the screen of the viewer. Now click the far right button on the toolbar, the “analyze” button. The image will go from a color to grey scale. You are now seeing a grey scale infrared image of your field. Under the toolbar and to the left, you will see an analysis type window with a drop down arrow. Click on the arrow then click on “medium definition.” The image will change to a false color, classified image with eight color levels. The color classes are the different vegetation vigor levels of the field. The color bar on the bottom of the image shows the relative low to high vigor. To the right under the tool bar is a slider bar for analysis level – moving the bar to the left will generalize the color or vigor groups and show fewer and fewer groups. Moving the slider to the right will show more groups and provide a more detailed view of the field.
Experiment with both the analysis type and the analysis level to show the patterns in your field that you saw there. Have a fun and productive time analyzing your fields.
