In order to grow and develop, plants need to absorb all kinds of nutrients from the soil, including a large number of elements and medium and microelements. But it is the relatively small amount of available nutrients in the soil that determines the plant's yield. Supplementing other nutrients without regard to the minimum nutrient will not improve crop yields. The minimum nutrient is the nutrient that the soil has the least capacity to supply, and that’s what we’re trying to supply.
