This law, which goes into effect June 21, regulates manure and fertilizer applications in 11 watersheds that make up Lake Erie’s western basin. It also limits Lake Erie dredging and requires wastewater treatment plants to monitor P levels monthly.
Experts in the region don’t think the law will have a major effect on fertility practices for no-tillers and strip-tillers, although some may want to be a little more meticulous with their record keeping.
The law’s main impact on farmers is the timing for spreading manure, nitrogen (N) and P fertilizers.
Growers can’t surface-apply manure or fertilizers if the ground is snow covered or frozen, or if the top 2 inches of the soil are saturated from precipitation.
The law doesn’t provide a definition for saturation, but Frank Gibbs, former NRCS soil scientist and consultant in Rawson, Ohio, says in soil science terms it means that all of the soil pores are full of water.
“The water that would normally drain out by drain tile, those pores would still be full of water,” he explains.
Granular forms of fertilizers can’t be broadcasted if the local weather forecast predicts more than a 50%…
