In a certain range, the higher the carbon dioxide concentration, the stronger the photosynthesis of plants, so carbon dioxide is the best gas fertilizer. Us scientists at a farm in New Jersey used carbon dioxide to do a lot of experiments on different growing seasons of different crops. During these two periods, when carbon dioxide gas was sprayed twice a week, four to five times a week, vegetables increased by 90 per cent, rice by 70 per cent, soybeans by 60 per cent and sorghum by 200 per cent.

The future is promising, but scientists are not sure how much carbon dioxide each crop will absorb.

German geologist Wolfgang ehrenst found that plants thrive where underground gas is coming out of the ground. So he sent liquefied natural gas into the soil via a special pipeline, and the special gas fertilizer remained in effect for two years. It turns out that methane gas, the main ingredient in natural gas, is used to help soil microorganisms reproduce, which can improve soil structure and help plants absorb nutrients adequately.
