Nitrogen losses in saturated soils

Recent rainfalls have brought about an abrupt change to soil conditions in some Ontario fields in just a few short weeks ago.  Localized heavy rainfalls have left some fields with standing water in low-lying areas, while many fields are wet or saturated.  This has raised questions about the potential losses of nitrogen (N) for the […]

Summary Background Throughout the growing season, microbes within the soil break down organic nitrogen contained in soil organic matter and release it as plant-available ammonium.  This process is known as nitrogen mineralization. Nitrogen mineralization is favoured by warm soil temperatures with adequate soil moisture and aeration.  Excess moisture can slow mineralization or increase the potential […]
