How farm management influences water quality in a challenging, diverse landscape
Both watersheds lost soil, phosphorus, and nitrogen. Average monthly losses while the ground was frozen and after crop canopy was established were similar between the two sites.
Soil and phosphorus were mostly delivered to the stream in May and June during storms.
A grade stabilization structure dam reduced the amount of soil delivered to the nearby stream.
By the end of the study, baseflow nitrate concentrations at the north site were similar to the south site, showing that targeted nutrient stewardship makes a difference.
Manure impacted phosphorus and nitrogen loss on two out of 2,557 days monitored, illustrating that timing of manure application matters.
