The tissue structure of plants, especially cellulose, sugar, etc. In the original ecological environment, each plant species formed over hundreds of millions of years has a certain proportion of carbon from the air and carbon from the soil. However, in artificial planting, especially when organic fertilizers are ignored and chemical fertilizers are applied, this proportion is out of balance. This has caused problems such as thinning of crop leaves, puffiness of stems (less dry matter), poor taste, easy disease, and premature plant aging. This in turn proves that the absorption of carbon dioxide by the stomata of crops cannot replace the absorption of water-soluble carbon by the roots. Applying carbon fertilizer to the roots of crops is essential.
