How to Fertilize your plants for bumper harvest - Henlus - 04-24-2026
Plants need 17 essential nutrients to grow well. These are grouped into macronutrients, secondary nutrients, and micronutrients.
Macronutrients (also come from air and water): Carbon ©, Hydrogen (H), Oxygen (O), Nitrogen (N), Phosphorus (P), Potassium (K).
Secondary nutrients: Calcium (Ca), Magnesium (Mg), Sulfur (S).
Micronutrients: Iron (Fe), Zinc (Zn), Copper (Cu), Manganese (Mn), Boron (B), Molybdenum (Mo), Chlorine (Cl), Nickel (Ni).
Most normal fertilizers (NPK) only give nitrogen, phosphorus, and potassium. This is not enough for full plant growth.
Plants also need other nutrients to stay healthy and avoid problems like poor growth, weak stems, and low fruit production.
You can get these extra nutrients from compost, manure, micronutrient sprays, or complete fertilizers.
Manure will take care of many macro and secondary nutrients, supplying elements like nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur in a more balanced and natural form.
It also improves soil structure, enhances water retention, and supports beneficial microbial activity, all of which contribute to healthier plant growth.
But manure alone may not give enough micronutrients, so extra feeding may still be needed depending on your soil and plants.
Conclusion
In addition to NPK, use enough manure and spray foliar fertilizer (the ones with micronutrients) weekly. If you can, include potassium sulphate and calcium nitrate in the foliar fertilizer. Do this if you want bumper harvest.

Plants require 17 essential nutrients, grouped into macronutrients, secondary nutrients, and micronutrients. Each plays a vital role in plant growth and development.
Macronutrients (including those from air and water)
Carbon ©: Forms the backbone of organic compounds; obtained from carbon dioxide in the air.
Hydrogen (H): Involved in energy transfer and plant metabolism; obtained from water.
Oxygen (O): Essential for respiration and energy release; obtained from air and water.
Nitrogen (N): Crucial for amino acids, proteins, and chlorophyll formation.
Phosphorus (P): Involved in energy transfer, root development, and genetic material.
Potassium (K): Regulates water use, activates enzymes, and improves disease resistance.
Secondary Nutrients
Calcium (Ca): Supports cell division, cell wall strength, and fruit quality.
Magnesium (Mg): Central component of chlorophyll and aids phosphorus movement.
Sulfur (S): Important for amino acids and enzyme function.
Micronutrients
Iron (Fe): Essential for chlorophyll formation and energy transfer.
Zinc (Zn): Important for hormone production and enzyme activity.
Copper (Cu): Supports enzyme systems and reproductive growth.
Manganese (Mn): Involved in photosynthesis and nitrogen metabolism.
Boron (B): Aids cell wall formation and flower development.
Molybdenum (Mo): Helps in nitrogen conversion within the plant.
Chlorine (Cl): Plays a role in photosynthesis and water regulation.
Nickel (Ni): Required in small amounts for enzyme activity, especially in nitrogen metabolism.

This is very clear and helpful. Many farmers focus only on NPK and wonder why crops still perform poorly. The missing link is usually those secondary and micronutrients. Once you understand this, farming becomes more predictable

Compost is also very underrated. Proper compost can supply a wide range of nutrients slowly and also improve soil life, which is very important for long-term farming

The mention of potassium sulphate and calcium nitrate is very useful. Many people only know NPK 15-15-15 and think that is the only fertilizer available

I think micronutrient sprays should be more common. Zinc and boron deficiencies can reduce flowering and fruit set without showing early warning signs

Manure quality matters a lot. Some manure is too fresh and can burn plants or introduce weed seeds. Proper composting makes a big difference.

Farmers should also learn to read plant signals. Leaves, stems, and fruit size can tell you what nutrient is missing if you pay attention

In sandy soil areas, nutrients leach very fast. So even if you apply everything correctly, you need more frequent feeding compared to clay soil.
