WC Mn/Dakotas | Depends on which micro and your soil. But I don't think nutrients move as much as many think. Yes they can be mobile but that doest mean they just float freely forever. They will attach chemically along the way if possible and then only continue to move if they precipitate out beyond what is held by soil or organic matter or other minerals. But again it depends on the nutrient and your soil.
If they moved as freely as you suggest, the movement is likely to exceed root growth. And maybe in some cases that is true in complete sand and high moisture situations. But in many other more common soils and especially when many notill situations when they refer to nutrients flowing down worm holes, I just don't think it freely moves by floating like water does. It is going to interact along the way.
Now if your soil is that saturated that nothing attaches, why are you applying more? Temperature also plays a role and ultimately it needs to be in a plant available form when the plant needs it. Iften that is very early and then again late. Most experts say placement is key. If everything is so mobile placement would not be so "key".
