Book Description
Phosphorus is an essential nutrient for life, but excess phosphorus in runoff from manure applied to agricultural fields can lead to negative environmental impacts such as harmful algal blooms. Water-extractable phosphorus (WEP) is correlated with phosphorus runoff from land-applied manure, but can change depending on the water content of a sample. Understanding how total phosphorus (TP) and WEP partition through livestock manure management systems can aid attempts in preventing phosphorus pollution of watersheds by increasing knowledge of how to remove it at its source. A number of dairy farms use solid-liquid separation in order to make the manure easier to handle. This produces a mostly solid material which can be re-used in the dairy barns as bedding for the cows, as well as a mostly liquid material which is applied to the fields. However, little is known about the partitioning of WEP through solid-liquid separation.
