On: Historic fertilizer crunch threatens food security

[jvanderbot]

Synthetic fertilizer does have negative impacts, but saying they have negative food impacts borders on oxymoron.

Runoff to freshwater inducing toxicity is one major impact from over fertilization, which is not an implication of the product itself, but it's over use.

I'm told. IANA farmer but I know many and worked with ag and water quality researchers for a few years in MN, USA.

Not just overuse, but use on land that is too close to bodies of water without riparian buffers.

And also wrong dispersal. All the fertilizer that gets on the water is wasted and does nothing but increase the farmer expenses.
