1. Inorganic (Chemical) Fertilizers

These are man-made fertilizers produced using chemical processes. They provide nutrients quickly and are widely used in large-scale farming.

• Nitrogen Fertilizers – Urea, Ammonium Sulphate, Calcium Ammonium Nitrate (CAN).

• Phosphatic Fertilizers – Di-Ammonium Phosphate (DAP), Single Super Phosphate (SSP).

• Potassic Fertilizers – Muriate of Potash (MOP), Sulphate of Potash (SOP).

• Complex Fertilizers – NPK blends containing Nitrogen, Phosphorus, and Potassium in one mix.

✅ Best for quick results and high-yield crops.

2. Organic Fertilizers

Organic fertilizers are made from natural sources and improve soil health along with providing nutrients.

• Farmyard Manure (FYM) – Cow dung, urine, and farm waste.

• Compost – Decomposed organic matter from crop residues and kitchen waste.

• Vermicompost – Nutrient-rich compost made with the help of earthworms.

• Green Manure – Crops like dhaincha and sunhemp grown and ploughed into the soil.

• Biofertilizers – Microorganisms like Rhizobium, Azotobacter, and Blue-Green Algae that naturally fix nitrogen or solubilize phosphorus.

✅ Best for improving soil structure, fertility, and sustainability.

3. Specialty Fertilizers

These fertilizers are designed for specific crops or advanced farming techniques.

• Micronutrient Fertilizers – Supply essential minerals like Zinc, Iron, Boron, and Copper.

• Water-Soluble Fertilizers (WSF) – Dissolve easily in water, ideal for drip irrigation and hydroponics.

• Slow-Release Fertilizers – Coated or treated fertilizers (e.g., neem-coated urea) that release nutrients gradually.

✅ Best for precision farming and modern agriculture methods.
