ABSTRACT

Ohio residents have been calling for changes in agricultural practices since harmful algal blooms have disrupted recreational use of lakes and drinking water supplies in the Western Lake Erie Basin. These blooms are a result of phosphorus (P) loading into waterways from a number of sources, including agriculture fertilizer and manure use on fields. P loss only accounts for about 0.49  lb/A  but  equates  to  roughly  2  million  pounds  of  P  each  year  being dumped into the Basin. Regulations have been put in place to educate farmers on  nutrient  management  and  reduce  nutrient  losses.  Three  tools  have  been updated and developed to help farmers reduce P losses: 1.) Updated Tri-State Fertilizer Recommendations, 2.) Updated Ohio Phosphorus Risk Index tool, 3.) Field Application Resource Monitor. These tools address the source, rate and timing of nutrient applications. The cost of implementing these practices varies  from  farm  to  farm.  Some  farms  may  see  no  change  to  their  budgets where other farms may see an increase in expenses.
