Influence of organic fertilizers on the issue of carbonic gas in the soil under vegetable crops

The article discusses the use of manure and other organic fertilizers serving for plants as a source of mineral nutrients with the release of CO₂ when decomposed, it saturates the soil air and the surface layer of the atmosphere contributing to the plant’s air nutrition. Field and laboratory experiments were carried out in 4-fold repetition in 6 varieties with legumes (beans and lentils), in 7 varieties with pepper, tomato, and eggplant. Mathematical calculation was performed to identify the correlation between the content of organic matter and the production of CO₂ from the soil. It was found that the higher the content of organic matter in the soil, the more it emits CO₂ under conditions of aeration and humidity, and the correlative high relationship confirms the contiguity and tightness between these parameters, where p = + 0.94 + 0.04 (beans); p = + 0.97 + 0.02 (pepper).
