Nitrogen Management on Fall Manure Applied Fields Using Intensive Grid Nitrate Sampling and Nitrogen Modeling

(2017)
Jason Gillis

While manure is a great source of many nutrients when growing corn, the natural variability of nutrient concentrations can create challenge. The nutrient management plan used on these fields should be different than fields utilizing strictly commercial fertilizer. This is especially true when making a nitrogen plan. Nitrogen is highly variable within all soils due to its chemistry. BY adding a source of nitrogen manure, that is not a uniform source of N either, the variance with the field only increases.

Impact of Fungicide Application on Nitrogen Use Efficiency on a Continuous Corn System with and without Fall Manure Application

(2017)
Jason Louks

Traditionally in a continuous corn rotation a nitrogen use efficiency (NUE) of between 1.0-1.2 pounds of nitrogen is considered standard. Prior to using PSNT to determine sidedress nitrogen rates this was the NUE observed on this farm. Once soil nitrate testing was implemented into the nitrogen program, an improvement to approximately 0.9-1.0 pounds of nitrogen per bushel produced. Once the investment was made to gain the ability to apply the sidedress using variable rate technology the farm NUE improved to an average of 0.7-0.85 pounds of nitrogen per bushel while still being on a com on corn rotation.

Fine Tuning Nitrogen Requirements for Economically Growing a Corn Crop

(2017)
Kyle Van Overbeke

My objective in requesting this grant is to fine tune my nitrogen requirements to grow a com crop and not leave valuable nutrients susceptible to leaching. I would like to compare the value in different Nitrogen Management decision tools. The tools I would like to compare are Encirca nitrogen model and 360 Yield Center’s Soil Scan machine. Both are designed to determine the in season Nitrogen needs of a growing com crop. I will also be comparing these two tools against soil samples sent to Midwest Labs for nitrate testing to determine accuracy of the decision tools.

Collecting your Data to Make Better Decisions with ON-Farm Analysis

(2017)
Michelle Hicks

With predictions of a several year cycle of lower com prices and tighter margins, our family wants to position ourselves with the ability to proactively lower costs by learning how to be our own Crop Consultants. Our hope is to develop a small accurate on farm soil testing lab. This would be in conjunction with developing our own crop scouting schedule to coordination reports with our local agricultural cooperative. We would like use different computer programs which would assist us in crop planning,

Examination of Zone Tillage versus Conventional Tillage

(2017)
Ron Anderson BWT Farms LLLP

BWT this year will be looking at the how “zone tillage” with a 3 coulter cart will affect the soils ability to infiltrate water and reduce surface run off while in a corn on corn situation versus the current SOP of tillage on corn. BWT will be soil sampling and tissue testing both systems to discover any differences. Water samples to be drawn from tile outlets from each system.

Soil and Water Improvement through Strip Tilling and Cover Crop Application

(2017)
Brad Nere

Observation during winter and spring 2015 showed some of the worst wind erosion in years. There was a significant amount of soil that was blown into the ditches around fields. The winter of 2016 also did not provide much snow cover which promoted wind erosion. We observed the acres we had custom strip tilled had significantly less erosion than our conventionally tilled acres. We attended the National Strip Till Conference which provided a lot of very good information and also provided networking with other farmers trying these practices.

Inter-seeding Cover Crops into V6 Corn while Side-dressing Nitrogen

(2017)
Keith Hartmann

My first objective is successfully establish a stand of annual ryegrass, oilseed radish and rapeseed into V6 corn while making an in-season nitrogen application. I will accomplish this by using the lnter-seeder/Side-dresser that I built in the spring of 2016 for the first year of my MN Corn Innovation Grant trials. During this past growing season, I established 28 plants/square foot or 85% germination using only 10lbs of seed per acre ($15/acres seed cost). That mix was annual ryegrass,

Integrating Swine Manure and Strip Till

(2017)
Dan Coffman

Manure application is a challenge in the fall for many farmers due to time constraints from harvest, weather, etc. Also, adopting new application practices also poses a challenge because “not everyone is doing it”. For this proposal, I’d like to develop and investigate a better more sustainable system for liquid swine manure applications. The land in my area is always excessively tilled (in my opinion); especially after manure applications and I keep thinking that there has to be a better way.

Investigating Aerial Seeding Cover Crops into Soybeans

(2017)
Dan Coffman

For this proposal, I’d like to demonstrate/investigate and possibly develop ideas regarding the seeding of cover crops into soybeans just before harvest. I will be looking at seeding systems (airplane & high clearance sprayer), two different cover crop blends, changes in soil health and soil erosion, and lastly, changes in management practices as well as the challenges that might be associated with that. The field selected is the same as last year. The east 30 acres will be split into 15 acre sections to investigate the different seeding systems,

Interseeding Cover Crops While Applying In-Season Nitrogen

(2016)
Keith Hartmann

This project will build a 12-row, 30-inch row spacing, cover crop interseeder that can apply liquid nitrogen and seed a cover crop in one pass. This will expand upon ongoing farm research using a small scale prototype interseeder that was built using commonly sourced Yetter Manufacturing strip freshener units, incorporating the seeds and a Gandy seeder. The project focus is to show farmers how they can successfully establish a cover crop in a northern climate and efficiently do that with one pass across the field during an in-season nitrogen application.
