Description

NPK (20:20:20)

 

Price: 130 Taka

Quantity: 50 gram

 

NPK 20:20:20 is a balanced water-soluble fertilizer containing equal proportions of Nitrogen (N), Phosphorus (P), and Potassium (K). It is widely used in agriculture, hydroponics, nurseries, rooftop gardening, vegetables, flowers, orchards, and commercial farming because it supports all-round plant growth.

Benefits in Gardening or Agriculture

A. Balanced plant nutrition

Contains equal amounts of all three major nutrients:

• Nitrogen → leaf and stem growth
• Phosphorus → roots and flowering
• Potassium → plant health and stress resistance

Because all are supplied equally, plants receive complete nutrition.

B. Improves vegetative growth

Produces:

• greener leaves
• larger stems
• stronger branches
• faster growth

Nitrogen stimulates chlorophyll production.

C. Better root development

Phosphorus:

• improves root branching
• enhances seedling establishment
• increases nutrient absorption

D. More flowers and fruits

Regular application often results in:

• increased flowering
• better fruit setting
• improved fruit size

E. Improves stress tolerance

Potassium helps plants tolerate:

• heat
• drought
• disease
• salinity stress

F. Fast acting

Being water soluble:

• absorbed rapidly
• suitable for foliar spray
• useful in hydroponics

G. Suitable during many growth stages

Can be used:

• early growth
• vegetative growth
• pre-flowering
• maintenance feeding

Community gardening discussions also describe 20:20:20 as a versatile “general purpose” balanced fertilizer usable through roots or foliar application.

Application Rate

Rates vary depending on crops and formulation.

Home gardening (pots)

Nutrient Contents

Some brands additionally contain:

Chemical Formula

NPK fertilizers do not have a single molecular formula.

They are produced by combining nutrient salts:

• Urea → CO(NH₂)₂
• Ammonium nitrate → NH₄NO₃
• Monoammonium phosphate → NH₄H₂PO₄
• Potassium nitrate → KNO₃
• Potassium sulfate → K₂SO₄

The final grade is labeled:

NPK 20–20–20

Chemical Contents Present

Typical composition:

Nitrogen forms:

• Urea nitrogen ≈10–11%
• Nitrate nitrogen ≈5%
• Ammonium nitrogen ≈3–4%

Phosphorus:

• P₂O₅ = 20%

Potassium:

• K₂O = 20%

Additional traces:

• Fe
• Zn
• Cu
• Mn
• B
• Mo

How It’s Made or Produced

Production process:

1. Raw chemicals selected

• urea
• ammonium compounds
• phosphate compounds
• potassium salts

2. Grinding and purification
3. Precise mixing
4. Addition of micronutrients
5. Granulation or crystallization
6. Drying
7. Packaging

Manufacturing requires controlled nutrient blending to achieve exact 20:20:20 composition.

Other Uses Apart From Gardening

Besides farming:

• hydroponics
• greenhouse cultivation
• turf management
• golf course maintenance
• landscaping
• lawn maintenance
• ornamental nurseries
• tissue culture units
• forestry nurseries
• research trials
