Detection Of Nitrate-N And Triazine Herbicides In Groundwater And Surface Water Of An Agricultural Watershed In Western Kentucky, John Potts, Larry Reber

Soil Science News and Views

The quality of water in Kentucky's agricultural watersheds has received considerable attention in recent years. The main concerns in com production areas usually center on content of nitrogen (N) from commercial fertilizer and triazines from herbicide applications in water. Although N can be found naturally in Kentucky soils, it can't supply all the N that com needs to produce optimum yields. Therefore, fertilizer N is added to ensure ample nutrition. Triazine herbicides, on the other hand, do not occur naturally in the soil but are applied to the soil to effectively control weeds. Most commonly, these herbicides are applied at …
