Chemical fertilizers disrupt the balance of soil microbes from "summary" of The Hidden Half of Nature: The Microbial Roots of Life and Health by David R. Montgomery,Anne Biklé

Chemical fertilizers, often touted as a solution to improve crop yields, can actually have unintended consequences for the health of the soil. When these synthetic fertilizers are applied to agricultural fields, they can disrupt the delicate balance of soil microbes that play a crucial role in nutrient cycling and plant health. The excessive use of chemical fertilizers can lead to an overabundance of certain nutrients in the soil, which can in turn alter the composition of the microbial community. Some microbes may thrive in this nutrient-rich environment, while others may struggle to survive. This imbalance can have far-reaching effects on soil health and fertility. Furthermore, the use of chemical fertilizers can also have a negative impact on the diversity of soil microbes. In a healthy soil ecosystem, a wide variety of microbes work together in a complex web of interactions to support plant growth. However, when chemical fertilizers are applied, they can disrupt this diversity by favoring certain types of microbes over others. As a result, the soil may become less resilient to environmental stresses such as drought or disease. This can ultimately lead to a decline in crop yields and the overall health of the soil. In contrast, organic fertilizers such as compost or manure can help to maintain a healthy balance of soil microbes by providing a more diverse array of nutrients and organic matter to support microbial growth. In order to preserve the balance of soil microbes and promote long-term soil health, it is important to consider the impacts of chemical fertilizers on the soil ecosystem. By adopting practices that support a diverse and resilient microbial community, farmers can improve the health and productivity of their soils in a more sustainable way.
