Nutrient Management Podcast: soil fertility - fact or fiction

On this podcast, Fabian Fernandez, Dan Kaiser and Carl Rosen explain what's fact or fiction in statements such as "plants prefer organic sources of nutrients because they are more available," "variable rate application of fertilizer will increase crop yield," and others. Listen and learn!

Reducing Bt trait acres in 2019 MN corn production? Implications for European corn borer

Bruce Potter, Extension IPM Specialist, Ken Ostlie and Bill Hutchison, Extension Entomologists
The economics of 2018 corn production challenged many farmers to minimize losses per acre. One area some farmers have targeted for reducing costs is hybrid selection. Planting corn hybrids without Bacillus thuringiensis (Bt) proteins for protection against European corn borer (ECB), corn rootworm, or both will greatly reduce seed costs. However, if not careful, farmers could inadvertently reduce crop revenues if they select hybrids without considering yield potential or insect populations in their fields.

Yield potential is the first thing to consider when selecting a corn hybrid. Bt traits only protect the yield potential of a hybrid; yield benefits only occur when targeted insects are above economic levels. When insect pressure is low or absent, economic benefit with trait-protected hybrids only occurs if higher costs are offset by greater yields. Switching to less-expensive non-Bt seed c…

Nitrogen Conference and Nutrient Management Conference

Join us in February for two essential conferences U of M Extension and Minnesota Agricultural Water Resource Center (MAWRC) are pleased to invite you to the Nitrogen Conference and Nutrient Management Conference.

Each conference offers continuing education credits (CEUs) in soil and water and nutrient management for Certified Crop Advisers (CCA).

5th Annual Nitrogen Conference February 5, 2019 in Mankato

This conference brings together experts to focus entirely on this valuable input. Current topics in crop production and environmental stewardship will be relevant and informative for today's agricultural producers and professionals.

View details on the Nitrogen Conference, including breakout sessions.

11th Annual Nutrient Management Conference February 19, 2019 in St. Cloud

Sessions will cover challenges in phosphorus and sulfur management, nitrogen applications under irrigation, and effects of phosphorus availability due to residue management.

Get more details on the Nutrient…

Soil fertility: fact or fiction?

Biostimulants: What are they and do they work?

In recent years, biostimulants have sparked an interest with many crop producers. With these products getting more attention, we find there is much to debate on their effectiveness. Before we discuss whether Extension recommends them, let’s talk about the different types and what they actually do.
What are biostimulants? A legal definition of biostimulants has yet to be decided. However, the European Biostimulants Industry Council describes them as “Substances and/or microorganisms whose function when applied to plants or the rhizosphere is to stimulate natural processes to benefit nutrient uptake, nutrient use efficiency tolerance to abiotic stress, and/or crop quality, independently of its nutrient content.”

There are many categories of biostimulants. The most popular are humic acids, seaweed extracts, liquid manure composting and beneficial bacteria and fungi.
Humic and fulvic acids – parts of soil organic matter resulting from the decomposition of plant, animal, and microbial resi…

Optimize corn hybrid selection

By Jeff Coulter, Extension corn agronomist
Hybrid selection is one of the most important decisions in corn production. Results from the 2018 University of Minnesota corn grain and silage performance trials are available at http://z.umn.edu/corntrials.

Hybrids that consistently perform well across multiple locations or years in a region are desirable because next year’s growing conditions are uncertain.

Consider trial results from multiple sources, including universities, grower associations, seed companies, and on-farm trials. Results from other corn trials are available at:
Minnesota Corn Growers AssociationIowa State University University of WisconsinNorth Dakota State University South Dakota State University Criteria for selecting corn hybrids for grain:
Identify an acceptable maturity range based on the growing degree days required for a hybrid to reach maturity. Selected hybrids should reach maturity at least 10 days before the first average freeze to allow time for grain dry-down…

Nutrient Management Podcast: On-Farm Research

On-farm research can provide great management benefits when done the right way. The key is in paying attention to the details and having a plan every step of the way. On this podcast, Brad Carlson, Anne Nelson and Dan Kaiser discuss what makes a good on-farm test, what to do with your data and how to ensure that data is good.
