Phosphorus Deficiency — ePlants Trade Nurseries

Phosphorus Deficiency in Plants. Phosphorus is equally important in plants. It is necessary that any gardener see to it that the phosphorus level on the soil remains sufficient otherwise; the plant will suffer from many illnesses and growth abnormalities.

Nitrogen, Phosphorous and Potassium and Their Role in

Phosphorus, when combined with water, breaks in to separate ions that can be absorbed by the plant's root system. The plant uses phosphorus for photosynthesis and energy/nutrient transport. The right amount of phosphorus can help crops yield more fruits and create healthier stocks and root systems, they may also mature much quicker than plants without phosphorus.

Because phosphorus moves slowly through the soil, it's important to work it into the soil, where it's needed by the roots. Potassium helps regulate plant metabolism and affects water pressure regulation inside and outside of plant cells. It is important for good root development. For these reasons, potassium is critical to plant stress tolerance.
