Carbon Dioxide in AgricultureBoosting plant growth and controlling pests while supporting organic agriculture

Carbon dioxide (CO₂) is a colourless, odourless gas produced by burning carbon and organic compounds, and by respiration. It is naturally present in air (about 400 parts per million¹) and is absorbed by plants during photosynthesis.

The Linde Group supplies CO₂ into many countries. A significant amount of the product is re-captured from industrial processes. This re-captured CO₂ is then condensed and purified, allowing it to be sold in cylinders or in bulk to a range of specifications, from food grade to industrial or agricultural grade.

CO₂ is a versatile molecule, supporting growth in plant life whilst also serving as a useful pest control tool. It is considered an organic treatment in many countries which means that the addition of CO₂ into the greenhouse or as a post-harvest treatment for produce will not impact the organic status of your produce. Consequently, with the growth in demand for organic produce increasing steadily internationally, CO₂ is part of the solution for many farmers and storage facilities worldwide.

CO₂ may be regulated for use as a fumigant or for use in greenhouse applications in your country and CO₂ safety monitoring should be conducted during applications. For more information, please contact your local Linde representative.
