Runoff from container nurseries contains nutrient and sediment from fertilizer and irrigation. We assessed runoff total suspended solids (TSS), N as total N (TN), and P as total P (TP) from a 5.2 ha production area of a mid-Atlantic nursery. TN and TP storm loads were approximately 900, 35 and 50 times greater than irrigation loads. While TN and TP were comparable to urban runoff, TSS was 2-4 times greater. The Storm Water Management Model (SWMM) was calibrated to the results and used to generate annual TSS, TN, and TP loading, providing a valuable planning tool for nurseries.

Ecological treatment methods such as slow sand filters, bioreactors, and algal turf scrubbers are low-cost, low energy technologies which harness the power of naturally-occurring microorganisms to remediate nutrients, agrichemicals, and pathogens in water. System costs are substantially lower than chemical disinfestation and remediation technologies. European horticultural growers have been using slow sand filters (SSFs) since the early 1990s, however SSFs have been used since the early 1800s to clean contaminants from water for human consumption. Recent research has shown that slow filters containing pumice and rockwool are able to effectively remediate pesticides and nutrients from irrigation water.

Plants With Purpose
Garcia-Chance, L., Majsztrik, J., and S. White (Clemson University)
Bioremediation, which is the process of using plants and microbes to remove contaminants from water and soil, has been used successfully in many different forms. Ornamental growers can use plants to effectively treat irrigation water. These systems are able to remove nutrients, sediment, and other contaminants from water before it is reused of runs off site. There are a number of different ways that bioremediation can be used at ornamental operations including installing floating mats on irrigation ponds which can save space, provide additional revenue, and reduce algae growth.
