Which major nutrient is often deficient in new turfgrass areas?

In new turfgrass areas, phosphorus is often found to be deficient due to several factors. When establishing a new lawn, phosphorus is crucial for root development and overall plant vigor. It plays a significant role in helping grasses establish themselves, particularly in the early stages of growth. New soil may lack adequate natural phosphorus, and it can also be tied up in forms that are unavailable to plants, further exacerbating this deficiency.

Many soil management practices, such as tilling and the inclusion of organic materials, can disturb existing phosphorus in the soil. Additionally, phosphorus is less mobile in the soil than nitrogen or potassium, meaning that its availability may not be uniform across a new planting area. As a result, monitoring phosphorus levels in new turfgrass installations is important for ensuring optimal growth and establishing a robust lawn.
