Optimizing Nitrogen Management 

For Corn Production

Decrease fertilizer use and maximize yields and profits with this 80 minute presentation by Iowa State University Agronomist, Dr. Alfred Blackmer, Ph.D.  Definitely a must see for any farmer!


  Nitrogen loss from your soil is costly as you not only lose the cost of the fertilizer, but the increase in yields will disappear as well.  In field studies, yields were increased 20, 30, and 40+ bushels per acre simply by changing application and monitoring of nitrogen based fertilizer.

  In this video, created in February 2001, Dr. Alfred Blackmer discusses the most up-to-date methods for managing your fertilizing needs.  In his presentation, he builds the foundation for nitrogen management, effectively decreasing fertilizer costs, increasing yields, and INCREASING PROFITS.

  Discover the effects of newly available technologies and their effect on fertilizer use, crop yield, and profits when added into your Nitrogen Management Cycle.  

  New technology, including satellite monitoring, allows for custom fertilizer application. Learn how to use the fertilizer you need ONLY where you need it.

  Discover why the old rules of thumb have been costing you money through decreased yields; including methods of applying liquid manure that although traditional, do not benefit crop yield because the nitrogen is lost before planting.  

  Discover how testing and adjusting field management can return increased yields and profits in your field.

  Dr. Blackmer defines strategies and techniques through the numerous charts and slides used to illustrate the information contained in this video.  This complex topic is presented in an easily understood form which can be applied to your cornfield this season.

  Discover how changes in your field affects soil condition, crop yields and profits.  Learn how to adjust fertilizer application across your field to optimize yield and increase profits.

This videotape will pay for itself 100's and 1000's of times with decreased fertilizer costs, increased yields, and increased profits!


The application of Nitrogen to farm fields is a “tried and true” yield increaser.

There is no question about the positive impact Nitrogen applications has on the farm economy.

Farmers use a tremendous amount of Nitrogen at a tremendous cost (millions of tons of nitrogen and billions of dollars each year).  Unfortunately, much of the costly applied Nitrogen is lost, and that is just money down the drain for the farmer/producer. 

A tremendous asset for the farmer is THIS VIDEOTAPE, "Optimizing Nitrogen Management For Corn Production," made available exclusively from EclecticVideos.com.  In this informative video produced on Feb. 28, 2001, Iowa State University Agronomist Dr. Blackmer, Ph.D., a noted researcher, teacher and lecturer, provides valuable detailed information, charts, and statistics to aid the farmer in more effective Nitrogen management.  As Dr. Blackmer notes, Nitrogen movement in fields has been traced to determine how much Nitrogen was left after two to three years.  The study showed that more that ˝ of the applied Nitrogen was lost by processes other than plant harvest.  This significant Nitrogen loss raises profit and environmental issues. 

If this Nitrogen loss situation isn’t corrected, farmers will continue to lose money in yield reduction and fertilizer loss.  Added to this, the Environmental Protection Agency will step in and bring about legislative regulations that will control the farmers’ Nitrogen application methods.  To solve the problem now is advantageous to both farmers and government, but more so to the farmer who is losing twice – once when he pays for the fertilizer that disappears from the field, and twice when he receives low yields due to the fertilizer loss.

The focus of this tape is to enable farmers to keep their applied Nitrogen in their fields.  Dr. Blackmer suggests changes that are necessary to solve the Nitrogen problem.  These are cost effective changes that should actually increase profits for the farmers.

This timely videotape offers new techniques, new knowledge, new promise, and new solutions.  The information it provides will help you to keep that costly Nitrogen in your field and consequently, increase your yield, and thus your profits.
