Linking fertilizer additions to changes in soil carbon and respiration rates
Abstract
Fertilizer application is a common agricultural practice aimed at enhancing crop productivity, but it also has significant implications for soil health and carbon dynamics. This article explores the relationship between fertilizer additions, soil carbon content, and soil respiration rates, which are essential indicators of microbial activity and soil health. While fertilizers boost plant growth, they can also alter the balance of soil carbon by stimulating microbial decomposition and influencing Soil Organic Matter (SOM). Increased microbial activity can lead to the release of carbon dioxide (CO2) from the soil, impacting the global carbon cycle. This review examines how different types of fertilizers (organic and synthetic) affect soil carbon dynamics and respiration rates, and it investigates the underlying mechanisms of these changes. Understanding these interactions is crucial for managing fertilizer use in a way that supports sustainable agriculture and minimizes environmental impacts such as greenhouse gas emissions.
