The regional publication, Effectiveness of Using Low Rates of Plant Nutrients, has been revised and updated. This publication was led by Dr. David Franzen, Extension Soil Science Specialist at North Dakota State University, and co-authored by the NCERA-103 Committee. The publication reviews the use of low rates of plant nutrients, specifically in-furrow or near-furrow starter fertilizer rates applied at corn, soybean, and wheat planting. There are many examples in the Midwest of the benefits of low rates of P at planting for corn production, but the overall profitability of low rates of P at that time is too variable in the rainfed corn belt to make a clear assessment. In contrast, there has not been a clear benefit to low nutrient rates (e.g. 2×2 starter or in-furrow starter) on soybean yield. Sugarbeet, canola, spring wheat and barley are crops that response profitably to low rates of P fertilizers. Ultimately, there are some cases where applying low rates (rates well below standard University guidelines) are profitable, but the benefit is only short-term as applying P at less than removal rates will ultimately result in a decline in soil test P levels, eventually compromising crop yield. Lastly, we conclude that foliar fertilization of macronutrients in the North Central Region is not an effective application method to supply these nutrients to crops.
