Another thing not mentioned so far:
Corn, as a crop, is what is known as a “heavy feeder” in terms of fertilizer. The runoff from all this fertilizer scoots directly down the Mississippi River and into the Gulf, resulting in the so-called “algae blooms” that enviros complain about. It’s believed that these play a role in the dead spots in the gulf.
So, in order to allow farmers to continue to overdose on corn/ethanol and the subsidies, they have removed phosphorous from your laundry detergent, dish soap, automatic dishwashing soap, etc. Which is why you’re washing a lot of things twice these days.
DJ69,
Ever spend some time actually looking at modern farming methods popular these days ? Successful farmers use sat photo data, GPS and computer-controls to preciselyh regulate the application of everything - from fertilizer to herb/pest cides - these days due to sheer economic neccessity.
Don’t suppose all that alleged “farm fertilizer” ran off lawns and from septic systems perchance ? Or sewage plants ? Even the USDA acknowledges more fertilizer, and control chemicals are used on lawns than crop land.
I’ve long proposed sampling of development runoff and comparing it to the same samplings of field runoff. Not had any takers yet....>PS
