Practical On-Farm Research: Why & How

Interest among farmers and their consultants for conducting field scale on-farm research has grown with the availability and adoption of a range of precision agriculture technologies that lessen the logistics of conducting many types of trials. However, conducting sound field research is not just about simpler logistics. It also requires an understanding and appreciation for the statistical and practical details of designing the trial, collecting the data, yield monitor calibration, yield data processing and cleaning, and fundamental statistical analysis. This presentation will shed light on many of these topics.

K & Soil Clay

North Dakota was primarily a wheat state until the early 1990’s. A string of wheat crop failures due to disease and insects, and the simultaneous development of early-maturing corn and soybean varieties, as well as the ease of weed control from their glyphosate-tolerant genetic traits spurred a great increase in corn and soybean acreage, with soybean now the dominant state crop and corn number 3 behind spring wheat/durum. The cropping change resulted in a corresponding decrease in soil K test values, since the previous small grain rotation removed very little K, while corn and especially soybean remove up to 4 times more K per season. A K rate study was conducted from 2014-2016 in fields with K soil tests between ~100-200 ppm. Data were collected...

Legacy Effects of Nitrogen Inputs on Crop Productivity and Fertilizer Nitrogen Use Efficiency

Nitrogen fertilization is critical to maximize corn productivity and replace nitrogen removed during harvest. Because nitrogen fertilizer inputs increase corn growth and residue return to the soil, agronomic optimum nitrogen fertilizer inputs help to sustain or increase soil organic matter over time, which may improve soil functioning. In this session, we will discuss how nitrogen fertilizer inputs affect soil organic matter levels, soil productivity, and fertilizer N recovery in continuous corn and corn-soybean systems.

Hybrid Differences in Nutrient Uptake

Corn hybrids change rapidly and most Corn Belt hybrids have a 2-3 year commercial lifespan. Seed company claims often suggest, based on their internal research or grower field experiences, that certain hybrids respond more to higher rates of fertilizers than others. There are also known hybrid differences in grain nutrient concentrations, and therefore in actual crop removal at particular yield levels. In this talk I will review preliminary evidence for possible hybrid differences in total nutrients taken up and in how the nutrients are allocated within corn plants at maturity. I will also briefly look at plant population impacts on nutrient uptake and nutrient partitioning during the...

Principles of Fungicide Resistance in Field Crops

Fungicides are an important tool for managing the threat of losses due to plant diseases. Unfortunately, the use of fungicides can lead to the selection of strains of plant pathogenic fungi that are resistant or less sensitive to the fungicides. This presentation will focus on the basic principles of fungicide resistance and will provide a case example of the frogeye leaf spot pathogen of soybean and its resistance to fungicides. Best management practices for delaying or slowing the selection of fungicide-resistant plant pathogenic fungi also will be discussed.

Intensifying the Use of Cover Crops in Organic Grain Systems in the Midwest

Cover cropping can positively impact several aspects of a healthy agricultural system, including reducing soil erosion, improving water quality, facilitating weed management, and providing habitat for beneficials and pollinators. However, in the upper Midwest, with its short growing season and unpredictable weather, intensifying cover crops across the rotation can be challenging. In this session, we will discuss some of the strategies we’ve researched at UW-Madison and how farmers have integrated these practices into their rotations, including interseeding into corn and cereal grains, managing cover crops as weed suppressive mulches, and utilizing intensive cover crop fallow/grazing phases as weed management tools.
