Deficiency of Nutrients
Deficiency of Nutrients
Deficiency of Nutrients:
When any macro- or micro-nutrient is absent or its concentration is less than the required amount, such a condition leads to a deficiency of that nutrient. The deficiency of nutrients leads to stunted growth, yellowing of leaves (due to less chlorophyll), reduced crop yield and even the death of plants. Manure and fertilizers are added to the soil to supply more nutrients.
Plants must obtain the following mineral nutrients from their growing medium:
The Macro-Nutrients:
Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), sulphur (S), magnesium (Mg), carbon (C), oxygen (O), hydrogen (H)
The Micro-Nutrients (or trace minerals):
Iron (Fe), boron (B), chlorine (Cl), manganese (Mn), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni)
Let us take an example of corn and see the deficiencies of nutrients and symptoms in the plants :
Nitrogen (N) deficiency causes pale, yellowish-green corn plants with spindly stalks. Because nitrogen is a mobile nutrient in the plant, symptoms begin on the older, lower leaves and progress up the plant if the deficiency persists.
