VIDEO: Taking the Basal Stalk Nitrate Test

Fabian Fernandez, Nutrient Management Specialist

The basal stalk nitrate test is a diagnostic test taken at the end of the growing season in corn. Results will show how well you did with your nitrogen management during the season. While this test won’t tell you how much N you need to apply next year, over time it can reveal a picture of your fertilizer management practices.

2017 U of M SE Minnesota regional soybean yield results now available

by Lisa Behnken, Fritz Breitenbach, Liz Stahl, and Ryan Miller
Performance comparisons of early (1.2-1.8) and late (1.9-2.3) maturity glyphosate tolerant/RoundUp Ready soybean in southeastern Minnesota are now available. The studies with 30 early-maturity and 30 late-maturity entries were conducted near Rochester, MN (Lawler site) on a Port Byron silt loam. Trials were planted on May 12, 2017 with a 4-row John Deere 7000 planter equipped with cone units. The seeding rate was 150,000 seeds per acre with seed planted at a depth of 1.5 inches in 30 inch rows. Plots were four rows wide by 22 feet in length and the center two rows of each plot were machine harvested on October 20, 2017.

Nutrient Management Podcast: Manure & Nutrient Availability

Nora Nolden, Communications Specialist
We're back with another Nutrient Management Podcast episode. This month, it's all about manure and nutrient availability. Fabian Fernandez, Dan Kaiser and Paulo Pagliari are joined by Extension's new manure management specialist, Melissa Wilson.

Manure and Nutrient Availability

Fabian Fernandez, Dan Kaiser, Paulo Pagliari and new manure specialist Melissa Wilson talk all things manure on this episode. Hear about sampling, application recs, best practices and more.

Oct. 5 Sauk Centre Hay Auction

by Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties, Crop Systems Focus, 320-968-5077,

Click on Links to my summaries from the Oct. 5, 2017 Sauk Centre Hay Auction.

1. Oct 7, 2017 Summary - All tested loads sold, groups based on hay and bale type and quality.

2. History of Selected Lots. Averages from recent years, and summer and fall sales so far.

3. Graph of Selected Alfalfa hay groups.
The 2016-17 season is the RED line.
I’m marking Summer, Sept, Oct 7 sales with a VERTICAL LINE indicating high, low, average.
I’ll start a 2017-18 new red line after the Oct 21 auction.

Harvest Note: It takes about 0.02 gallons of LPG per point of moisture removal per bushel to dry corn.

Five Tips for Getting the Most out of Fall Soil Sampling

Dan Kaiser, Soil Fertility Specialist

1. Sample at the correct depth
We calibrate soil test results to a specific sampling depth, so it's important to get this right. Immobile plant nutrients tend to accumulate near the soil surface, so shallow sample depths can inflate results. For immobile nutrients and soil pH, sample at zero to six inches. For fall nitrate, sample at zero to 24 inches.

Corn harvest, drying, storage challenging this year

Ken Hellevang, North Dakota State University Extension Service, and Dave Nicolai, UM Extension
Each year brings challenges for crop production, North Dakota State University Extension Service grain drying expert Ken Hellevang warns.

The U.S. Department of Agriculture estimates that 82 percent of the Minnesota corn crop is mature compared with a five-year average of 93 percent. As of Oct. 15, only 7 percent of the Minnesota corn crop had been harvested, compared with a 38 percent average.

Inhibitors for Fall Nitrogen Application

Jeff Vetsch, Soil Scientist

Soil temperatures are dropping and moving toward the 50 degree threshold for fall nitrogen applications. If you’re thinking about fall applications, should you use an inhibitor? Our research shows that nitrification inhibitors can protect fall nitrogen against loss and increase the amount of nitrogen present in the ammonium form the following spring, as long as best practices are followed.

UMN Extension Debuts Nutrient Management Podcast

Nora Nolden, Communications Specialist

University of Minnesota Extension's nutrient management team has a new way for you to hear the latest nutrient management research, timely news and seasonal information. Once a month, the team will share the most up-to-date trends and information on what we're seeing in fields across Minnesota.

Sept 21 Sauk Centre Hay Auction Summary

by Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties, Crops Focus, 320-968-5077,

Links are listed for summaries of Sauk Centre hay auction information for September 21.

1. Sept 21, 2017 Summary - All tested loads sold, groups based on hay and bale type and quality.

2. History of Selected Lots NOW INCLUDES AVERAGES FOR SEPT 2016 through MAY 2017, along with previous years.

3. Graph of Selected Alfalfa hay groups.

The 2016-17 season is the RED line. I'll start a new Line in October.

I’m marking Summer and September with a VERTICAL LINE indicating high, low, average.

SMALLER LOAD NUMBERS MAY NOT REPRESENT THE MARKET AS WELL. Compare to other market information. Remember your livestock and crop budgets are the key to what you pay or accept for hay.
