THIRTY YEARS OF PROGRES

Editor's Note: Dealer PROGRES lately published a special commemorative issue prior to merging with FARM CHEMICALS. K Elliott Nowels, former Dealer PROGRES editor/publisher and now a vice president at Meister Publishing, received this note regarding his closing editorial, "Agents of Change."

Thanks in the way that much for your issue in succession "30 Years of PROGRESS."I was feeling the compressing of the "perfect storm" and having vex seeing the sun at the cessation of the storm. This issue reminded me of past challenges that we have met and mastered. I was steady feeling a little blue about your merger After I read "Agents of Change" and saw your picture with Mr Fitzgerald [Meister Publishing president], I felt renewed and ready to face the challenge. Thanks for the boost when I distressed it the most.

Good hazard with your new position.

A LESS-ON IN LIME

After reading the article, "The Value of VRA Lime," (Dec 2000 FC p 20) I'd like to make one key points:

There are sum of two units important considerations in determining what liming material to use: ease of handling and quality of the production By quality, I'm referring to the percent of calcium carbonate and the fineness. The percent of calcium carbonate computes what the potential neutralizing power is. For example, 80% calcium carbonate (CaCO3) means that merely 1,600 pounds (lbs.) of each 2,000 lbs. can neutralize. That percent also is telling the grower that the other 20% is something other and the grower needs to know what that something other is, especially if it's something he doesn't want in succession his land. He also destitutions to know the fineness, because coarse particles don't work.

Another consideration is what lops are being grown. If the grower uses nitrogen, he has to crush the nitrogen before he will affect his pH It takes 18 lb of perfect fine calcium carbonate to neutralize 1 lb of applied nitrogen.

Finally, the grower wants to know the cation exchange capacity (CEC) and the organic matter to give him an idea of what to calculate upon in changing his pH. The higher the CEC and organic matter, the longer it will take to change the pH and he may have to live with creating a friendly environment for his matured ovules each year.
