Think "mass of fertilizer applied" like you do calories, and the eating process:

➡️ Small, frequent meals, versus few, large ones. Both can provide the necessary total mass of nutrients.
➡️ Taking small bites over the course of hours versus trying to jam an entire plateful of food in your mouth at once. Your environment dictates how acceptable the latter is - Martin Mote's environment allowed the solution to be absorbed before the water evaporated, bil's doesn't.
