Tractor Time Episode 13: 2017 Conference Highlights — Dr. Vandana Shiva, André Leu and Ronnie Cummings

Good day and welcome to Tractor Time, the podcast from Acres U.S.A. This was recorded on Dec. 21, 2017, from our offices in Greeley, Colorado. We’re coming off a high from our 42nd annual Eco-Ag Conference & Trade Show in Columbus, Ohio, and wanted to use this podcast to help us celebrate the highlights.

From left to right, Fred Walters, Dr. Vandana Shiva, Ronnie Cummings and André Leu, on Dec. 8, 2017, in Columbus, Ohio.

There were many. They included the 1,100 people who attended from 15 different countries, who gathered to hear diverse and interesting viewpoints on ecology and agriculture. Not only did we learn about the finer points of soil nutrition, micronutrients, microbiology, micro fungi, but we also learned about the larger picture, and how ecologically based agricultural practices can benefit all of our global systems, from climate change to world peace.

Soil Testing Based on Mehlich III Extraction Methods

Soil testing, wrote Jerry Brunetti in 2009, is the foundation for the actions you take to add fertility to your soil:

A farmer starts to test the soil.

I’ve always been a fan of foliar nutrition, especially on forages. However, I don’t advocate the application of foliar fertilizers as a replacement for sound agronomic practices involving comprehensive soil analysis (including multiple trace elements), tissue testing, and an evaluation of the soil ecology.

A soil test can be quite easy to interpret and recommendations can just as easily be made based on the results of the test. Since many articles on soil fertility have been written for Acres U.S.A., this article will provide the reader with an “ideal” test based upon a Mehlich III Extraction.

Forage tests generally determine whether or not you are on target with adequate feeding of the crop and are becoming considerably more revealing than in the past. This is especially true in the measurement of total digestibility and fiber digestibility, protein quality, and the various fractions of energy such as sugars, starches, digestible NDF, etc.
