4.1 Estimate nutrient loading from fertilizer

Understanding the relative contribution of fertilizer to nutrient loading can help prioritize management strategies. Loads may reasonably be estimated through an approach that calculates nutrient budget coefficients based on inputs, uptake, and outflows of nutrients for differing land uses.

6.1 Estimate annual nutrient loads from stormwater

Robust long-term monitoring and modeling programs that take into account surface and subsurface runoff, stream flows, and organic and inorganic nitrogen concentrations are essential for accurately estimating and managing nutrients in watersheds.
