In the second year of lime stabilized sewage application, what percentage of nitrogen is typically mineralized in the soil?

In the context of lime stabilized sewage application, the mineralization of nitrogen refers to the process by which organic nitrogen in the applied sewage is converted into inorganic forms that plants can readily utilize. By the second year of application, research and field observations indicate that about 15% of the nitrogen from the applied lime stabilized sewage is typically mineralized in the soil.

This mineralization rate is significant for nutrient management practices because it helps agronomists and farmers understand how much nitrogen will be available to crops over time. The organic matter introduced into the soil from lime stabilized sewage not only provides a source of nitrogen but also enhances soil structure and fertility, promoting sustainable agricultural practices. Properly accounting for this mineralization allows for more precise nutrient management plans, reducing the risk of over-fertilization and potential environmental impacts.
