471 - Compare On-Farm Results to Research


"It doesn't work that way for me." Growers make such statements and often these are accurate observations. For example getting complete control of Lambsquarters on the farm is often difficult, while Dr. Dexter almost always gets complete control. Weed control research trials frequently provide new or improved ways to control tough weed problems. Take careful note of the following facts:

Fact: Weeds are growers #1 problem 22 of the last 25 years (NDSU Survey)

Fact: Growers spend over $40,000,000 annually on weed control

Fact: Only 20% of all growers rated their weed control excellent in 2000-2004

Fact: 2005 Model Farm analysis indicates revenue losses to weeds are greater than $18 million annually.

In light of these facts take the opportunity to participate in the NDSU / U of MN 2005 weed control tours at a location near you. Get answers to those weed control problems experienced in 2005.

Zinc and Other Micronutrients for Sugarbeet Zinc - Responses to micronutrients have been rare in Minnesota and North Dakota in the past. Extensive zinc research by Allan Cattanach and John Lamb at 7 locations in 1988 and 1989 on low or marginal testing soils found no benefit from zinc fertilization.

Boron - Research to evaluate effect of Boron on sugarbeet yield and quality was conducted from 1987-1990 by Allan Cattanach et al. Sugarbeet did not respond to applications of dry fertilizer Boron or post emergence applied B liquid fertilizers. Research was conducted on low to medium testing fields for soil Boron.

Sulfur - Dr. John Lamb, University of Minnesota Soil Scientist conducted extensive research on sulfur fertilization of sugarbeet in the Red River Valley and Southern Minnesota. Sulfur fertilization did not increase yield or quality in any trial.

Calcium - Sugarbeet fields occasionally have exhibited typical calcium deficiency symptoms. However this is not due to inadequate available calcium, but an inability of plants to take up enough calcium to meet requirements for very rapid growth just after canopy closure. Some varieties are more likely to have this problem.

Other - Deficiencies of other micronutrients have not been documented in Minnesota and North Dakota.

Field Conditions Increasing Potential Benefit of Micronutrient Fertilization

  • Low organic matter
  • Coarse textured soils
  • Irrigated crops with very high yield

For more information on micronutrient fertilization of sugarbeet see the 1986 - 1990 Sugarbeet Research and Extension Reports

Drainage Needed

Standing water in beet fields points to a need for better drainage.

Contact your agriculturist to participate in a drainage pilot program cooperative effort of John Deere, Precision Partners and American Crystal Sugar Company. See what RTK can do for you.

A retirement event for Dr. Joe Giles will be held Monday, June 27, 2005 at the NDSU Alumni Center, 1241 North University Drive, Fargo, ND. Growers are welcome to attend.
