ACIDITY & LIMING
Produced: October 2021
Authors: Steve Culman, School of Environment and Natural Resources, The Ohio State University;
Anthony Fulford, School of Environment and Natural Resources, The Ohio State University;
James Camberato, Department of Agronomy, Purdue University;
Kurt Steinke, Department of Plant, Soil and Microbial Sciences,Michigan State University
Produced: May 2003
Description: Land is one of a producer's highest-priced assets. To get the most return from your investment, you need to insure adequate fertility. Thus, soil testing should be a key part of your crop production program.
Authors: David B. Mengel; Stephen E. Hawkins
Produced: May 2003
Description: Outlines the causes or sources of acidity in soils, defines how to measure such acidity, and discusses how to determine soil liming needs and appropriate rates of application. Also discusses quality characteristics of liming materials.
Authors: S. Hawkins; Jeff Phillips; David B Mengel
MANURE NUTRIENT MANAGEMENT
Produced: May 2003
Description: This publication describes how to estimate the capacity of 3 types of manure spreaders: liquid tank, V-bottom, and a box.
Authors: S Brichford; Brad Joern
Produced: May 2003
Description: This publication discusses the challenges of land application, reducing runoff, minimizing leaching, and developing a nutrient management plan. A table is included listing the steps to help maximize manure nutrient-use efficiency and minimize potential impacts on water quality.
Authors: Brad Joern; Allen Sutton
Produced: September 1993
Description: This publication describes how to estimate the capacity of three types of manure spreaders: liquid tank, V-bottom, and a box.
Authors: Brad Joern
MICRONUTRIENTS
Produced: May 2003
Description: Lists recommended varieties and discusses management steps needed to ensure adequate fertilization, proper seedbed preparation,and optimum stand establishment of wheat in Indiana.
Authors: Mansfield, C. W.
Produced: July 1990
Description: Provides information on micronutrient needs of common Indiana field crops and how to prevent deficiency problems.
Authors: David B Mengel
NITROGEN
Updated: 2022
Produced: October 2019
Authors: James Camberato; RL (Bob) Nielsen; Jason Lee; Cody Hornaday
Produced: April 2003
Description: Nitrogen fertilizer is essential for profitable corn yields, but is also a major production cost and can contribute to environmental degradation. This publication provides information about soil nitrate tests, collecting samples and interpreting results.
Authors: Sylvie Brouder; Dave B Mengel
Produced: May 2003
Description: Getting the correct amount of Nitrogen needed for optimal corn yields can be difficult. However, using a chlorophyll meter can help determine the amount of Nitrogen a corn plant has been able to accumulate. This publication provides information for using and interpreting a chlorophyll meter.
Authors: Sylvie Brouder; Dave B Mengel
Produced: April 2006 / Updated 2015
Authors: John Sawyer, Iowa State University;
Emerson Nafziger, University of Illinois;
Gyles Randall, University of Minnesota;
Larry Bundy, University of Wisconsin–Madison;
George Rehm, University of Minnesota;
Brad Joern, Purdue University
Produced: February 2005
Description: Monitoring nitrate nitrogen in field drainage tile outlets has important implications for water quality and efficient production agriculture. This publication provides some general guidelines for interpreting nitrate concentrations in drainflow samples and describes the most important factors influencing drainflow concentrations.
Authors: Sylvie Brouder
Produced: September 2003
Description: Studies have demonstrated that the nitrogen (N) status of a corn crop can be determined by measuring the nitrate concentrations in the lower portions of cornstalks at the end of the growing season. Evaluation of the test in Indiana has demonstrated that maintaining a database of "end-of-season cornstalk nitrate test" values is a good fine-tuning and quality-assurance tool for better N management practices in corn. When crop yields meet or exceed reasonable yield objectives, the test can be used to determine if soil N supply during the growing sea- son exceeded the needs of the crop.

Description: Lists recommended varieties and discusses management steps needed to ensure adequate fertilization, proper seedbed preparation,and optimum stand establishment of wheat in Indiana.
Authors: Mansfield, C. W.
Produced: May 1986
Description: The purpose of this publication is to answer questions concerning types and uses of nitrogen fertilizers for crop production. It is hoped that the information presented will help Hoosier farmers more accurately assess their current fertilizer programs and make those adjustments that will maximize their fertilizer dollar.

SECONDARY NUTRIENTS (Calcium, Magnesium, Sulfur)
Produced: January 2022
Authors: James Camberato; RL (Bob) Nielsen; Diana Salguero; Dan Quinn
Produced: December 2021
Description: This presentation shares what we know and don't know about corn response to applied sulfur fertilizer in Indiana, based on field scale research we conducted throughout the state from 2017 - 2021. While it is true that more fields of corn respond to sulfur today than decades ago, it is also true that many fields do not require sulfur fertilizer for optimum yield.
