It still must be applied according to soil test needs, and in a manner that provides the most effective utilization of nutrients. This generally means proper placement in a band close to the seed and proper timing of applications, including foliars. There are additional benefits from using High Performance crop nutrition. One big advantage is time. Reduced rates applied per acre also means less on-farm storage is needed.
Broadcasting can increase phosphorus loss due to fixation with iron or aluminum.
But banding dry fertilizer too close to the seed can cause injury. According to Liebig's Law of the minimum, a plant will only produce up to the level at which a nutrient becomes in short supply, even though all other essential nutrients are in sufficient amounts. Foliar feeding of certain crops is another option with High Performance crop nutrition. This was evident in an experiment at the North Central Research Station. In soybeans in an area with manganese deficiencies, a planter fertilizer lacking manganese was applied.
