An organic farmer claimed that organic inputs (fertilizers) cause just as much damaging runoff as commercial synthetic fertilizers -- releasing too much nitrogen, phosphorous, and other nutrients at once, causing runoff to waterways, disrupting balance, and leading to things like algae blooms. I realize farmers should focus on growing sustainable soils full of healthy microbes vs. using fertilizers, but I need some perspective on comparisons of organic fertilizers with synthetic ones, and the longterm effects. Thanks for any help.
