Nitrate and Sulfur in Fall Grazed Cover Crops

---

Abstract

It is well known that annual grasses and brassicas utilized as cover crops can accumulate nitrate, and brassicas may accumulate sulfur. Most samples tested through this project would be considered safe for nitrate while about half tested high in sulfur. A link between forage nitrate and sulfur levels to manure application or soil fertility levels was not able to be identified in this study due to variability in fertility practices across farms sampled. Further research is needed to understand the impact of manure and soil fertility level on the nitrate and sulfur level in fall grazed cover crops.
