Farmers grow crops over the years in the same piece of land. Level nutrients in the soil depletes after every crop cycle; which causes deficiency of nutrients in soil.
Nutrient deficit plants show various symptoms such as yellowing leaves, stunted growth, etc. Thus, it is highly essential to identify deficiency in order to maintain healthy growth & development of plants.
How to do this? Check out below:
Identify Plant Nutrient Deficiency?
Following table shows list of nutrients & their corresponding symptoms which can be identified on the plant leaves.
Deficiency Symptoms of Major Nutrients:
|Nitrogen (N)||:||Yellowing of older leaves (bottom of plant). The rest of the plant turns light green.|
|Phosphorus (P)||:||Older leaves turn reddish-purple. Leaf tips look burnt.|
|Potassium (K)||:||Older leaves wilt, look scorched. Interveinal chlorosis begins at the base, scorching inward from leaf margins.|
|Sulfur (S)||:||New leaves turn yellow first, followed by older leaves.|
|Magnesium (Mg)||:||Older leaves turn yellow at edge leaving a green patch in the center of the leaf.|
|Calcium (Ca)||:||New leaves (top of plant) are distorted or irregularly shaped.|
Deficiency Symptoms of Micro Nutrients:
|Boron (B)||:||Terminal buds die.|
|Copper (Cu)||:||Leaves turn dark green. Plant is stunted.|
|Iron (Fe)||:||Yellowing occurs between the veins of young leaves.|
|Manganese (Mn)||:||Yellowing occurs between the veins of young leaves. Reduction in size of plant parts (leaves, shoots, fruit) generally. Dead spots or patches|
|Molybdenum (Mo)||:||Yellowing of older leaves (bottom of plant). The rest of the plant turns light green.|
|Zinc (Zn)||:||Terminal leaves forms rosette. Yellowing occurs between the veins of the new leaves|
What to do if deficiency is found?
- Fertilizer containing nutrient which is deficient in the soil should be applied; as soon as deficiency is identified.
- There are plenty of manufacturers who provide good quality major & micro nutrient fertilizers.
E.g. Major nutrient fertilizers: Mahindra, RCF, Coromandel, Mahafeed, etc.
Micro nutrient fertilizers: Maxim, Aries Agro, Green Crop Agro, Multiline, Anjali Biotech, Alert Biotech, etc.
