carbon use in horticulture … CO2 enrichment

Carbon dioxide is wunderbar, says a horticulturalist at WUWT. In fact, carbon in many forms is used in fertilizing crops and improving soils. CO2 generators have been posted on earlier.

CO2 is Wunderbar
Having followed and read many articles about the benefit of CO2 for plant life, many of them from http://www.co2science.org/ I have wanted to experiment with CO2 enrichment here at the golf course I work at. The big problem is having a way to provide the gas to the plant in an economical and practical way. As I looked around the internet I may have found one. The company http://greenfield-fertilizer.com/ has recently arrived in Canada and is based in Europe, Germany I think, and has been marketing their material for a few years.

The material is very finely ground up minerals, carbonates of Mg and Ca. When sprayed on the plant the fine materials enter the stomata break down and give off CO2. With this enrichment the stomata can close a little which reduces water loss and so you get better growth with a more drought tolerant plant. Well at least that’s the idea which seems to make sense and the company offers a number of studies with very good results.

Just received a pail of the material and am amazed at how fine it is, 25 pound pail is $150 which is quite cheap considering some of the other adjuvants we routinely spray on our greens. Pail will last for six weeks and we will test next year spraying bi-weekely with other nutrients. Even if there is a 10-15% improvement in turf growth/hardiness it is a big improvement on greens that are cut at .100 inch every day. Would be great for gardeners to try and it is completely non toxic, just mind the fine powder.

Several analyses have been conducted to estimate potential monetary damages of the rising atmospheric CO2 concentration. Few, however, have attempted to investigate its monetary benefits. This study addresses this discrepancy by providing a quantitative estimate of the direct monetary benefits of atmospheric CO2 enrichment on both historic and future global crop production. Results indicate that the annual total monetary value of the increase in the air’s CO2 content (since the inception of the Industrial Revolution) for world crop production grew from about $18.5 billion in 1961 to over $140 billion by 2011, reaching the staggering sum of $3.2 trillion over the 50-year time period from 1961-2011. And projecting the monetary value of this positive externality forward in time reveals that it will bestow an additional $9.8 trillion on crop production between now and 2050.
