Generally, nutrient availability to crop roots is function of soil moisture, soil pH, level of nutrient's concentrations in the soil and extensiveness of root hairs network. You should google how the factors influence nutrient availability to crop roots?
Fertilizer response depends on the initial level of available form of a target nutrient in the soil solution in that fertilizer, available soil moisture to dissolve the nutrient from the fertilizer carrier , soil fixation capacity of a particular nutrient (Soil pH is key determinant) to be available and type and quality of fertilizer itself. You should google for details of mechanisms?
