First, the larger view and philosophies of HB 490 make quite a bit of sense. There is no argument there and that is why the legislation has general support from agriculture. Politically, many feel more needs to be done by agriculture to improve water quality in Lake Erie. HB 490 seems like a reasonable response from a proactive Ohio agriculture.
On the other hand, any time factors like weather, soil, nutrients, and water are a part of legislation, a broad brush is often used to cover the small details that really matter when it comes to complex challenges such as water quality. It also should be noted that the principles of HB 490 rely heavily on tried and true conservation practices that have been used in the past, which is when the problem with water quality got its start. This is a problem that demands change and a new way of looking at things based upon answers to questions that are not yet known.
