Default Re: Does Global Warming Make Food Less Nutritious?

The crap some people will believe

Let me be the first to bust the myth,,,;

Green houses have been adding CO2 to their plants routinely for years.

Introduction

The benefits of carbon dioxide supplementation on plant growth and production within the greenhouse environment have been well understood for many years.

Carbon dioxide (CO2) is an essential component of photosynthesis (also called carbon assimilation). Photosynthesis is a chemical process that uses light energy to convert CO2 and water into sugars in green plants. These sugars are then used for growth within the plant, through respiration. The difference between the rate of photosynthesis and the rate of respiration is the basis for dry-matter accumulation (growth) in the plant. In greenhouse production the aim of all growers is to increase dry-matter content and economically optimize crop yield. CO2 increases productivity through improved plant growth and vigour. Some ways in which productivity is increased by CO2 include earlier flowering, higher fruit yields, reduced bud abortion in roses, improved stem strength and flower size. Growers should regard CO2 as a nutrient.

For the majority of greenhouse crops, net photosynthesis increases as CO2 levels increase from 340–1,000 ppm (parts per million). Most crops show that for any given level of photosynthetically active radiation (PAR), increasing the CO2 level to 1,000 ppm will increase the photosynthesis by about 50% over ambient CO2 levels. For some crops the economics may not warrant supplementing to 1,000 ppm CO2 at low light levels. For others such as tulips, and Easter lilies, no response has been observed.

I don't use it in my greenhouse because it connects to the house. If it didn't, if it was freestanding, I would pump what is used to heat the building back into the operation. As I learned to do back when I worked at a Truck farm greenhouse.

The natural carbon cycle is the process of using sunlight to lock CO2 into the plants for growth and later consumption. It is the only justification for experimenting with Algae and Biomass systems of sustainable carbon fuels.
