Reduce fertilizer or herbicide use near peatlands

Background information and definitions
Fertilizers and herbicides can have negative effects on peatland vegetation if they spill over from agricultural or domestic land (Smolders et al. 2010). Herbicides can kill plants directly. Run off from fertilized land can carry excess nutrients (such as nitrogen and phosphorous) into peatlands, altering their naturally low nutrient levels. Simply applying less fertilizer or herbicide to agricultural land near peatlands could reduce the amount spilling over into peatlands. Ultimately, reduced chemical application could be driven by legislation, financial incentives and/or education.
Key peatland types for which this action may be appropriate: bogs, fens/fen meadows, tropical peat swamps.
Related actions: other techniques to reduce fertilizer or herbicide runoff into peatlands, without necessarily reducing the total amount applied.
