what will be the consequences of deficiency of micro and macro nutrients
Answers
Nitrogen is the most critical nutrient for optimum farm production. Since it is readily leached from the soil, its level in soil is typically low, however the levels required for optimum crop growth are quite high and thus generous application is typically required. Nitrogen reduces all aspects of crop and pasture production e.g. growth, yield and quality.
Symptoms of Deficiency :-Plants which have Nitrogen for only limited growth, may exhibit chlorosis especially in the older leaves. In severe cases, the leaves first yellow and then tan as they die. Some plants (tomatoes, maize) may exhibit a purplish colouration of the stems, petioles and on the underside of their leaves .
Deficiency of micro and macro nutrients in plants can cause various diseases.
● Nitrogen is a macronutrient and its deficiency in plants can cause change in the colour of leaves and can also lead to death of the leaves.
● Phosphorus again is a macronutrient and its deficiency can lead to stunted growth and delay in maturity.
● Chlorine is a micronutrient which aids plant metabolism and its deficiency can lead to slower root growth.
● Boron is again a micronutrient and is essential for seed and fruit production and its deficiency can cause death of terminal buds.
