partially. Over fertilization, which causes nutrient runoff (by definition wasteful and not cost effective) is not required to grow the amount of food that we grow.
Targeted fertilization or erosion control can both mitigate it by reducing waste, saving money and reducing occurance of side effects at the expense of a reduction fertilizer sales worldwide.

Don't think precision agriculture would scale. And even if it would scale, meaning we would theoretically be able to grow a lot more food on a lot less land, it would only mean that we'd grow more food and especially that we'd have even cheaper food. The Jevons paradox is real.
