Solvita C02 Soil Health Test Webinar Nov 19

Dear Ed,
Thank you for registering for "The Relevance Of Soil Biology In Assessing Fertility & Soil Health".
The subject of soil health is capturing everybody’s attention. The big question is whether no-tillers can test and measure the health of their soils and determine how it might be impacting their yields and the supply of nutrients to their crops. Get an understanding of how soil labs are working to integrate carbon dioxide respiration tests with common nutrient tests as a means of providing a broader picture of soil fertility through our upcoming No-Till Farmer webinar sponsored by Woods End Labs on Wednesday, November 19, at 10 a.m. Central time.

Here’s what you’ll learn:
• How soil biology directly and indirectly can influence crop growth
• How soil biology analyses fit in with the testing of soil nutrients
• Examples of how soil biology is related to fertility and soil management
• How to use soil respiration in soil testing to improve nutrient recommendations and potentially save on nitrogen costs without sacrificing yields

Will Brinton, the inventor of the Solvita® CO2 soil test, will help no-tillers understand the relationship between soil biology and efficient nutrient uptake from the soil profile through this 60-minute webinar. For more information about this upcoming No-Till Farmer webinar sponsored by Wood End Labs, call Lucas Rumler at (800) 451-0337 or email him at

I plan to attend and you can sign up yet today or tomorrow.  I encourage you to do that so we can work on this together in the next year.

Why measure CO2 respiration?

Soil and plants interact in the search for and supply of nutrients. Soil provides the environment for plant growth while plants participate in building and sustaining soils by releasing exudates and leaving behind their own residues. This dynamic cycle is best described as the soil-plant system. In the process, humus is formed and carbon dioxide (CO2) is released due to microbial activity. The relationship between these processes is an important indicator of soil fertility.
Declining rates of CO2 respiration are associated with intensive tilling, compaction and over fertilizing. These soil practices are potentially destructive and inhibit the soil’s ability to sustain its humus content, the natural reservoir of organic nutrients and soil life.  As soil declines,  microbes starve for food and the rate ofh CO2 respiration decreases, indicating deteriorated soil quality.
Being able to evaluate the turnover of organic matter via CO2 respiration is important for a number of reasons:

Lets see what we can learn!
