I would largely disagree with these responses for a number of reasons. Yes dry costs are less than liquid pound for pound usually, but when it comes to plant available i will largely disagree. Infurrow popup is not meant to feed the plant all year, its about ensuring you have enough plant available npkzn early when soil is too cold to physically have enough plant available naturally. This is also highly efficient placement vs bcasting, so less does more. Dry or liquid planter placed bands are also very effectient placement wise but can take away from the primary purpose of planting. Again, i dont really think this should be the primary source of nutrient placement. I like it as a 2nd stage of a relay fert program. I like the bulk of my pk placed a min of 4" deep, ideally 5-6". Less than that is a risky proposition. Phosphorus is highly reactive. If the plant doesnt use it, it will atrach to something. Many times it becomes something not plant available. When and at what rate it becomes plant available is hard to know and impossible to plan for. It does not move in the soil very much at all despite what many growers would like to think is physically or chemically possible.
