REMINDER: Registration open for “Strategic Farming-Maximizing Return on Investment” Workshops

By Lizabeth Stahl, Extension Educator-Crops, and Seth Naeve, Soybean Extension Specialist

Ten opportunities remain to attend one of the 2019 “Strategic Farming – Maximizing Return on Investment” workshopsAt these sessions, key cost factors in crop budgets will be discussed, as well as the likelihood for a return on investment on practices ranging from a foliar fungicide application to a "build and maintain" soil fertility program.  Soybean aphid management strategies, seed and trait technologies, tips to evaluate marketing claims, and best management practices to ensure the marketability of grain will also be discussed.

Manure applied on frozen soil or snow - what will happen to my nitrogen?

By Melissa Wilson, manure management and water quality Extension specialist

It was a tough fall for manure application. In many places of the state it was wet and harvest was delayed. On top of that, winter arrived earlier than it has in the past couple of years. Many people were forced to apply manure on top of frozen soils or even snow. We’ve gotten a lot of questions about how the nitrogen in the manure will be impacted.

When manure is applied on the surface of frozen soils or on top of snow, we have two concerns. First, it cannot seep into the ground, so if there is any runoff in your fields, it can carry the manure to low spots or away from the field entirely which may cause environmental issues. We have already seen widespread rain in December across southern Minnesota and snow melt in January in many parts of the state. Fields with higher amounts of residue are less likely to have as much runoff as fields with low residue, so this problem may be worse in some fields and not oth…

Updated list of aphid-resistant soybean varieties available for Minnesota

by Siddhi Bhusal, Anthony Hanson, Aaron Lorenz and Robert Koch

An updated list of commercially available aphid-resistant soybean varieties that are suitable to grow in Minnesota can be found in a revised version of an Extension publication titled, Aphid-Resistant Soybean Varieties for Minnesota. Soybean aphid is one of the major pests of soybean in Minnesota, causing significant yield loss. Management of soybean aphid has relied on foliar insecticides, but insecticide resistance has developed in this pest and poses a challenge for soybean production. Planting aphid-resistant soybean varieties can help to reduce insecticide inputs, and thereby decrease selection pressure for further development of insecticide resistance. Aphid-resistant soybean varieties can provide an effective, economical, and more environmentally sustainable means of protecting soybean from soybean aphid. Soybean breeders have developed soybean varieties that carry aphid-resistance traits, in addition to other promi…

Refocus on Wheat

Minnesota’s hard red spring wheat acreage rebounded to 1.6 million acres in 2018.  This 40% jump is probably easiest explained by the record yields the previous year and the lackluster futures for corn and soybeans for much of the 2018 marketing year.  The large carry forward of soybeans and continued uncertainty in the export market mean that a further increase of wheat acres is possible, if not likely.
The University of Minnesota Extension has teamed up with the Private Pesticide Applicator Training program to help (re)acquaint farmers with spring wheat and provide the latest production and management tactics for the upcoming growing season.  The combined PPAT/Small Grains Update meetings will be held at the Comstock Community Center, the Ada Event Center, the Marshall County Courthouse in Warren, and the Roseau City Center on January 28, 29, 30 and 31st, respectively. 
At each location, the meeting will start at 9:00 AM and end at 2:30 PM. Pre-registration is required for the upda…

Winter barley

Jochum Wiersma, Small grains specialist, Becky Zhong, Research assistant
The arctic cold snap of the past two days may have you doubt the data. However, climatologist are sure that Minnesota’s winter are getting milder and wetter while the summers are getting more humid with nighttime lows creeping higher. The latter is especially worrisome for production of high quality malting barley.

Transitioning from a summer annual growth habit where you seed the crop in early spring and harvest the crop the same growing season to a winter annual where you seed the crop the previous fall and harvest it the next summer is a way to better exploit growing conditions that favor cool season annuals like barley and wheat. The winter growth habit allows these cool season crops to mature earlier, thereby escaping the summer heat that affects yield and quality adversely.

While winter wheat is well suited for Minnesota, winter barley is not (yet). The University of Minnesota’s barley breeding program…

Nitrogen Smart is back for its fourth year

Join University of Minnesota Extension for Nitrogen Smart, a program for producers to help maximize economic return on nitrogen and minimize losses. View dates and locations.
Why attend Nitrogen Smart? According to a survey of past participants:
Over 3 out of 4 of attendees changed at least one practice as a result of attending the meeting.Our survey data of past participants and estimates show at least a $3,243 value for each attendee, when calculating acreage, rate reduction and potential increased yield in timing of application. Attendees who complete the morning fundamentals session receive a three-year certificate. New this year: the Advanced Nitrogen Smart session, which focuses on manure management, is available in the afternoon to returning participants or to new participants that attend the morning fundamentals course. Nitrogen Smart is also available as an online course. Get more details on dates, locations and the online option.

Register Now for “Strategic Farming-Maximizing Return on Investment” Workshops

By Lizabeth Stahl, Extension Educator-Crops, and Seth Naeve, Soybean Extension Specialist

In crop production, what is the likelihood of seeing a positive economic return from a foliar fungicide application or a “build and maintain” soil fertility program? Which strategies are worth the time and money when managing soybean aphid? What seed and technology trait decisions are the most important for your operation?

Hear the latest University of Minnesota research and information addressing these questions and more at the 2019 “Strategic Farming – Maximizing Return on Investment” workshops. Not only will key cost factors in crop budgets be reviewed, but tips will also be provided to help you evaluate ag research and marketing claims in order to make the best management decisions on the farm.

Soil-water basics for irrigation scheduling

By Vasudha Sharma- Extension Irrigation Specialist
During the past few years, irrigated agriculture has increased significantly in Minnesota. Most of the irrigation in the state happens in the glacial outwash region where irrigation makes this region highly productive because of low water holding capacities and rapid drainage, however this is where most people depend on groundwater for their drinking water supply. Contamination of groundwater due to agricultural nitrate leaching and decreased recharge to lakes and streams because of high groundwater withdrawals for irrigation are two critical environmental problems in the central sands region of Minnesota.

Strategic irrigation management can address the complex challenges we face in the central sands region. Irrigation management enables the irrigator to apply the right amount of water at the right time, which increases irrigation efficiency and reduces nitrate-N leaching. However, proper irrigation management is a difficult task. Ov…
