      P has a lot of fractions (forms) with only the soluble inorganic forms and some organically bound forms available.

      Other organic forms are present in microbes and the soil biome to support living critters (ATP).

      Other more recalcitrant forms serve only to replenish the soluble and organic pools

          Tillage isn’t bad if you are using it to incorporate organic amendments.

          if you plant very deep rooting plants, they can pull P from deeper horizons, but it’s slow. Test your soil, determine your P goals, and then apply an amendment, such as wood ash (careful with pH)
