Fertilization Guidelines for Mature Apple Trees Nitrogen Phosphorus Potassium Calcium Magnesium Boron Zinc Interpreting foliar nutrient analysis can sometimes be challenging for growers, particularly when trying to determine whether fertilizer applications are needed and at what rate. While leaf nutrient concentrations provide valuable information about the nutritional status of the trees, fertilization decisions should not […]
Article Contents Introduction Agronomic Implications of Stratification Research About Stratification Key Takeaways References Introduction Stratification, or the unequal distribution of nutrients within the soil profile, has been well documented across Wisconsin, with the most concentrated nutrients existing within the upper 2” of soil in all fields. Having reduced or eliminated tillage on more acreage across […]
Farmers across Wisconsin and Minnesota have long known that healthy soil grows better crops. Now, data collected directly from working farms helps back that up with numbers. A study using fields from the UW-Madison Extension Discovery Farms program and Discovery Farms Minnesota found a clear connection between higher soil organic matter and higher corn yields, and the results come from real farms, not just research plots.
