Effect of light on soil microstructure and soil elements

Abstract

light has certain energy, so it can change the soil microstructure and the elements in the soil when it radiates the soil. In this paper, the changes of total nitrogen and organic carbon in the soil under white light were studied. The results showed that: the light had an activation effect on the organic carbon in the soil; the light exposed the organic matter in the soil, accelerated the decomposition of organic matter, and reduced the total content of organic carbon. The results show that the infrared light has no effect on the soil structure, and the ultraviolet light can change the soil structure.
