Introduction to Plant Nutrition and Nutrient Deficiency

Adequate nutrition is essential for healthy plant growth. Plants require a range of nutrients, each playing a specific role in their development.

A lack of these nutrients can result in a condition known as nutrient deficiency, where plants may display symptoms such as yellow leaves, stunted growth, and reduced yield.

Understanding plant nutrient deficiencies and their symptoms is crucial for maintaining a healthy garden.

Essential Plant Nutrients and Their Functions

Plants require a mix of macronutrients and micronutrients. Plants need macronutrients in more significant amounts, including nitrogen, phosphorus, and potassium. These nutrients are crucial for plant and root growth, and seed and fruit production.

Micronutrients, required in smaller amounts but still essential, include copper, manganese, zinc, boron, molybdenum, and iron. These play roles in various processes, like nutrient absorption, enzyme activation, and chlorophyll production.

Symptoms of Nutrient Deficiencies


Deficiency Symptoms


Nitrogen (N)

Older leaves become yellow (chlorosis) and may drop. Stunted or slow growth.

Add composted manure or a high-nitrogen fertilizer.

Phosphorus (P)

Older leaves may show a dark green or purplish color. Reduced flowering or fruiting. Stunted growth.

Add bone meal or rock phosphate fertilizer to the soil.

Potassium (K)

Yellowing and browning or scorching at leaf edges. Reduced disease resistance.

Add potassium-rich fertilizer or composted banana peels.

Calcium (Ca)

New growth is affected with distorted or irregularly shaped leaves. Terminal buds may die.

Apply gypsum or lime to the soil.

Magnesium (Mg)

Older leaves show interveinal chlorosis, remaining a brilliant green. Leaves may become reddish or purple.

Add Epsom salt or a magnesium-rich fertilizer.

Sulfur (S)

New growth turns pale yellow, older growth stays green. Stunted growth.

Add sulfur or sulfate-based fertilizers.

Iron (Fe)

Yellowing between the veins of young leaves. In severe cases, the entire leaf turns yellow or white.

Add iron chelate or iron sulfate.

Manganese (Mn)

Yellowing between the veins of young leaves, while veins stay green. Brown spots may appear.

Apply manganese sulfate or chelated manganese.

Zinc (Zn)

Reduced leaf size, shorter internodes, leaf chlorosis. In severe cases, leaves may become white.

Add zinc sulfate or chelated zinc.

Copper (Cu)

Leaves become dark green and curled. Growth is stunted.

Apply copper sulfate or copper chelate.

Boron (B)

Yellowing of leaf tip followed by browning and die-back. Terminal (end) buds may die.

Add borax or a boron-based fertilizer.

Molybdenum (Mo)

Older leaves show interveinal chlorosis, remaining a brilliant green. Twisted younger leaves.

Add a fertilizer that contains molybdenum or add lime to acidic soils.

Please note that remedies for nutrient deficiencies vary depending on the soil type and plant species. Please consult a plant health expert or conduct a soil test before applying any treatment.

Correcting Nutrient Deficiencies in Plants

Once a nutrient deficiency is identified, correcting it is next. This often involves amending the soil with the appropriate fertilizer containing the deficient nutrient. The amount required will depend on the extent of the deficiency and the specific plant’s needs.

Remember that factors like soil pH and water levels can also affect nutrient availability. For instance, in overly acidic or alkaline soil, certain nutrients may need to be sufficiently available to plants, even if they are present.

Preventing Nutrient Deficiencies

Prevention is always better than cure. Regular soil testing can help you maintain the proper nutrient levels, allowing you to supply your plants with the nutrients they need in the right amounts. This will result in healthier, more productive plants, reducing the risk of deficiency symptoms developing.


Understanding plant nutrition and identifying nutrient deficiencies is vital for any gardener. With this knowledge, you’ll be well-equipped to diagnose and treat nutrient-related plant problems, leading to a healthier, more vibrant garden.
