NPK (0:0:50) – 50 gram

Description

NPK (0:0:50)

 

Price: 130 Taka

Quantity: 50 gram

 

NPK 0:0:50 is commonly known as Sulphate of Potash (SOP) or Potassium Sulfate fertilizer. It contains 0% Nitrogen (N), 0% Phosphorus (P), and 50% Potash (K₂O) and is mainly used where crops require high potassium and low chloride fertilizer. It is especially preferred for fruits, vegetables, flowers, tea, tobacco, and high-value crops.

Benefits in Gardening and Agriculture

A. Improves fruit size and quality

Potassium regulates carbohydrate movement and sugar formation. Crops become:

• Larger
• Better colored
• Sweeter
• More attractive
• Improved shelf life

Examples:
Tomato, mango, grapes, watermelon.

B. Increases flowering and fruit setting

Potassium:

• Activates enzyme systems
• Improves flower formation
• Reduces flower drop
• Increases fruit retention

Useful for:
Rose, chili, tomato, brinjal, cucumber.

C. Makes plants resistant to diseases

Plants become more resistant against:

• Fungal attack
• Bacterial diseases
• Stem weakness
• Fruit cracking

D. Improves drought tolerance

Potassium controls stomata opening and closing.

Benefits:

• Better water use efficiency
• Less wilting
• Increased heat tolerance

E. Improves crop yield

SOP enhances:

• Number of fruits
• Fruit weight
• Grain filling
• Overall productivity

F. Strengthens stems

Helps reduce:

• lodging in rice
• weak stems
• branch breakage

G. Improves root development

Though potassium mainly affects quality, adequate K supports root growth.

H. Chloride-free fertilizer

Unlike MOP (0:0:60), SOP contains almost no chloride.

Useful for chloride-sensitive crops:

• Potato
• Tobacco
• Tea
• Citrus
• Strawberry
• Grapes

Application Rate

Application varies by crop and soil test.

Field crops:

40–90 kg/ha

Fruits:

60–120 kg/ha

Vegetables:

40–80 kg/ha

ow It Is Made / Produced

Commercial SOP is produced mainly by:

Mannheim Process

Reaction:

Potassium chloride + sulfuric acid

2KCl + H₂SO₄ → K₂SO₄ + 2HCl

Steps:

1. Raw materials mixed
2. Heated in Mannheim furnace
3. Chemical reaction occurs
4. Cooling
5. Granulation
6. Drying
7. Packaging

Alternative methods:

• Natural brine extraction
• Salt lake processing
• Mineral extraction

Other Uses Apart from Gardening

Industrial use

• Glass manufacturing
• Fire-resistant materials
• Chemicals production

Animal feed

Potassium source

Pharmaceuticals

Certain specialty applications

Laboratory reagent
