True or False? Established turf never needs phosphorus.

The assertion that established turf never needs phosphorus is false. While established turf generally requires less phosphorus compared to newly seeded or heavily stressed areas, there are situations when it may benefit from phosphorus applications. For example, if soil tests indicate low phosphorus levels, or if there is a need to promote root growth or recovery from stress, phosphorus can be beneficial.

Additionally, phosphorus plays a critical role in various plant processes, including energy transfer and photosynthesis, and can enhance overall lawn health. It's essential to consider soil health and nutrient availability when assessing the need for phosphorus in established turf. Thus, maintaining healthy soil and knowing the nutrient status can guide decisions on fertilizer application, including phosphorus.
