Extension specialists and educators provide timely resources and information to help Wisconsin crop producers and their agricultural consultants manage crops efficiently and profitably.
In this video, Hava Blair, researcher, UW–Madison Department of Soil and Environmental Sciences, presents an in-depth overview of the Wisconsin Phosphorus Index (P Index), a modeling tool used to estimate phosphorus runoff from agricultural fields to nearby surface waters.
In this video, Kelsey Hyland and Laura Paletta from UW–Madison Extension’s Ag Water Program explore phosphorus stratification in Wisconsin agricultural soils and its implications for water quality.
Chris Clark and Landon Baumgartner, UW–Madison Extension Nutrient and Pest Management Team, discuss why getting seed depth right is the key to achieving uniform emergence and strong roots.
Dan Marzu, UW–Madison Extension Nutrient and Pest Management Outreach Specialist, and Guolong Liang, UW–Madison Extension Agriculture Water Quality Outreach Specialist, discuss managing nitrogen in potato and vegetable crops.
Nutrients are vital for crop development and yield outcomes, but they are also an input cost that should be optimized for profit; not yield alone. This document serves as a centralized resource containing soil fertility information for small grain crops.
An overview of Dr. Rebecca A. Larson’s research focused on real-time nutrient sensing in manure using a near-infrared (NIR) sensor system.
Chris Clark presents data from 29 years of manure samples, highlighting trends in micronutrient levels such as calcium, magnesium, sulfur, boron, copper, zinc, manganese, and iron and whether these levels are sufficient for common row crops.
Dr. Natasha Rayne discusses the concept of manure nitrogen credits and their importance in agricultural nutrient management, how nitrogen credits are calculated, the variability in nitrogen content across different types of manure, and the factors affecting nitrogen availability.
In this article, we present some foundational considerations related to soil health testing and describe situations where soil health testing can provide useful information about specific soil functions to farmers, landowners, agronomists, and crop consultants.
Join Francisco Arriaga as he explores the latest soil conditions and management strategies for spring 2025.
High soil test phosphorus is a challenging issue that requires a combination of strategies for long-term nutrient management. Start here to understand all the tools you have in your phosphorus management toolbox.
This article highlights the characteristics of healthy soil and describes how these characteristics, and soil health generally, can contribute to sustainable crop production and indirectly impact society beyond the farm field.
