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

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.

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.

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.

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: 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.

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.
