Nitrogen Timing: Apply When the Crop Needs it Most

Benjamin Davies, Soil Science PhD Student
Paulo Pagliari, Extension Soil Scientist

Spring is right around the corner. Do you have a nitrogen management plan in place? The rate and timing of nitrogen application should depend on your soil type, crop rotation and historical management practices. Recent University of Minnesota research funded by AFREC found that in coarse-textured soils, producers should split apply urea and in finer textured soils, plan to apply urea in the spring or as a split application.

Nutrient Management Podcast: Sulfur 101

Tune in to the latest Nutrient Management Podcast for a refresher on sulfur. Dan Kaiser, Jeff Vetsch and Paulo Pagliari discuss when to apply sulfur, where responses happen and what sources to use. They'll also talk about which crops are impacted by sulfur response, where sulfur is stored in the soil and how it is made available to crops.

Sulfur 101

On this episode of the podcast, Dan Kaiser, Paulo Pagliari and Jeff Vetsch give you the what, when, where, why and how of sulfur. Tune in for more on where sulfur responses occur, how it's made available to crops, what source to use and the best time to apply.

Evaluating Spring Phosphorus Availability in Minnesota

Paulo Pagliari, Extension Soil Scientist

Phosphorus is an essential element for crops, especially in the spring because it stimulates early plant growth, giving the plant a healthy and vigorous start. Spring phosphorus availability can range from low levels in western Minnesota to high levels in the southeastern, central and east-central areas of the state. Here’s a look at how to manage phosphorus this spring, based on the latest research.

Eleven Nitrogen Smart meetings on deck

Brad Carlson
University of Minnesota Extension is pleased to announce the schedule for the third year of its popular Nitrogen Smart program. Nitrogen Smart is an educational program designed to provide the information necessary to evaluate nitrogen fertilizer options. Farmers attending this program learn how to maximize profits from nitrogen applications while minimizing environmental impacts.

Applying Manure This Spring? Start Planning Now

Melissa Wilson, Extension Manure Management Specialist

It may be hard to imagine spring coming anytime soon with the recent arctic temperatures, but in a few short months it’ll be time to apply nutrients for the upcoming crops. If you plan to apply manure, now is the time to start mapping out your plans for the year to save headaches down the road. Here are some tips to get you started on your plans and for applying manure this spring:

Workshop for crop advisers on soil health

Jake Overgaard, UMN Extension Educator
UMN Extension will be hosting a workshop focused on soil health and cover crops for crop advisers and other ag professionals on February 28th at the Heintz Center in Rochester.

While interest builds around the use of cover crops and other ways to improve soil health, crop advisers can play a key role in providing up-to-date information on their benefits to clients while ensuring their fit with other farm management goals.

Benchmarking yield potential for soybean in North Central States

Peyton Ginakes and Seth Naeve

Photo: Lisa Behnken The University of Minnesota is partnering with nine other North Central states to close the soybean yield gap by combining big data from producers with location-specific modelling.

Models are capable of predicting maximum yield potentials based on soil type, weather data, and management practices. However, yield gaps exist where producers’ soybean yields fall short of maximum yield potentials. That’s why ten North Central states are conducting a survey for more detailed information from soybean producers. Survey results from thousands of producers across the region allows researchers to use a ‘big data’ approach in determining which management practices can close the yield gap in localized regions. More information on what researchers have concluded thus far can be found in the Corn & Soybean Digest article, Data pegs soybean yield gap.

Small Grain Winter Workshops

Jared Goplen
University of Minnesota Extension is offering four Small Grain Winter Workshops in Central, Western, and Southern MN in February to address small grain production.

Row crop farming brings busy spring and fall workloads. There are also pests common to row crops, including herbicide resistant weeds, soybean cyst nematodes, soybean aphid, diseases and corn rootworm. Small grains added to a rotation may offer opportunities to diversity cropping systems in central and southern Minnesota to manage these challenges and lower production costs. This program is designed to help farmers determine if small grains can work on their farm, in their rotation, and if it can be sustainable over time. This program will provide the tools needed to make small grains a successful crop in their operation. This includes information on production agronomics, variety selection, disease identification, fungicide use, fertility, quality, equipment, and economics. Time will be set aside for o…

Time Sensitive: EPA Seeks Input on Registrations for 4 Neonicotinoid Insecticides

(Information provided by US EPA and Jan Knodel, Extension Entomologist, NDSU, Fargo, ND)
There is an EPA open public comment period for ecological risk assessments for EPA registration review of four neonicotinoid insecticides. This open comment period ends Feb 20, 2018.

The announcement for this review is available at: https://www.regulations.gov/document?D=EPA-HQ-OPP-2011-0581-0102. This is an opportunity for the agricultural community to comment on the benefits of these widely used insecticides.
