What are the symptoms of Phosphorus deficiency and excess in plants
20 July 2023, New Delhi: Plants absorb various nutrients to grow. Any imbalance in nutrients may affect the final produce. Hence, a thorough examination of the growing plant can help in identifying particular nutrient stress. Typical signs may show up if a plant is deficient in a specific nutrient. A nutritional deficiency does not immediately result in symptoms. Instead, the regular plant processes are disturbed, leading to an overabundance of some intermediate organic molecules and a deficiency in others. This results in abnormalities that are later recognized as symptoms.
Symptoms of Phosphorus deficiency and excess in plants
Deficiency
Plant growth will be slow and stunted and the older leaves will have a purple coloration, particularly on the underside.
Excess
Phosphorus excess will not have a direct effect on the plant but may show visual deficiencies of Zn, Fe, and Mn. High P may also interfere with normal Ca nutrition, with typical Ca deficiency symptoms.
