Know how farmers can detect the deficiency of nutrients in plants.

Like humans, plants also suffer from nutrient deficiencies, to fulfill which they also have to depend on external nutrients. But, the problem arises when we do not understand which nutrient is lacking in them. Let us tell you today, how you can identify it in a plant. Healthy plants are essential for a thriving garden or successful harvest. Lack of nutrients can affect the growth and development of plants, causing growth to stop. At the same time, the leaves also turn yellow and the production of fruits or flowers gets spoiled. 


Healthy plants are essential for a thriving garden or successful harvest. Lack of nutrients can affect the growth and development of plants, causing growth to stop. At the same time, the leaves also turn yellow and the production of fruits or flowers gets spoiled. Today we will provide you with information about which element is deficient in plants and when. Plants need many essential nutrients for their growth and development. These nutrients can be broadly divided into two groups. Macronutrients and micronutrients.


Macronutrients

Plants require macronutrients in abundance and these include nitrogen (N), phosphorus (P), potassium (K), calcium (CA), magnesium (MG), and sulfur (S).

Micronutrients

Micronutrients are required in small amounts and include iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), and chlorine (Cl).


Recognizing the symptoms of nutrient deficiencies

Nutritional deficiency in general: Plants are seen based on the characteristics of their leaves, stems, and growth. Let us tell you that based on some common symptoms, we will give you information on how you will be able to identify the deficiency of which element in a plant.


Deficiency of Nitrogen (N): Yellowing (chlorosis) of older leaves that starts at the tips and spreads inwards, stunting growth.

Deficiency of Phosphorus (P): Dark green leaves with red-violet color, older leaves may turn blue-green or brown and curl.


 Deficiency of Potassium (K): Yellowing or browning of edges and tips of leaves, weak stems.


Deficiency of Iron (Fe): Interveinal chlorosis (yellowing between the veins) on new leaves, leaves may turn white or yellow.


Deficiency of Magnesium (Mg): Interveinal chlorosis on older leaves, leaves may turn red-violet or curled.


Deficiency of Calcium (Ca): Young leaves may become distorted tips may die back, and flower tips in fruits may rot. 


Deficiency of Sulfur (S): Yellowing of new leaves, stunted growth, and reduced seed and fruit production.


Micronutrient deficiency: These vary depending on the micronutrient. For example, iron deficiency causes interveinal chlorosis. Also, zinc deficiency causes leaves to become small and distorted. 


If you see these symptoms in any plant, then you can very easily identify which nutrient is lacking in that plant. Once the symptoms are known, you can easily find the treatment accordingly.
