The latest proposal by the Maryland Department of Agriculture regulating phosphorous levels has been scrapped before it voted on the new rules.
The department held two rounds of public hearings where strong opposition came from the poultry industry.
However, the department said it will continue to work with stakeholders to come up with a set of regulations which will be resubmitted sometime next year.
Kevin Anderson, a farmer from Princess Anne and president of the Maryland Grain Producers Association, said the new regulations would put a financial strain on farmers.
He said smaller farmers would be especially hit if forced to turn to more expensive commercial fertilizers.
But state agricultural officials said the regulation is important to protect the environment.
