ASABE Annual International Meeting. Technical Abstract: The identification and assessment of conservation practices continues to be important for the protection of natural resources. Buffers, also referred to as filter strips, buffer strips, riparian buffers, or vegetative filters are one of the most common types of conservation practice installed in the US. Data were collected on a weekly basis from 8 different streams in the Upper Big Walnut Creek (UBWC) watershed representing different types of buffers (wooded, herbaceous, and no buffer). Water samples from each stream were analyzed for nitrate-nitrogen, total nitrogen, dissolved reactive phosphorus, and total phosphorus. Buffer type had a significant effect on nitrogen concentrations but no effects were detected for phosphorus. The findings suggest that for nitrogen control buffers may play a significant role; however, with respect to phosphorus the buffers will have to be modified or enriched to be statistically effective.
