Introduction

Gel fertilizers are rapidly gaining attention in Indian agriculture due to their
high nutrient use efficiency, water-saving ability, and
controlled nutrient release.

However, the success of gel fertilizers depends not only on the product itself, but also on
how and where it is applied. Unlike traditional granular fertilizers that are broadcast across the field,
gel fertilizers work best when applied strategically and precisely near the root zone.

Correct application can significantly improve crop growth, yield, and profitability, while incorrect use can reduce efficiency.

Why Application Method Matters for Gel Fertilizers

Gel fertilizers are designed to:

• Release nutrients slowly
• Stay near the root zone
• Reduce leaching and runoff
• Improve nutrient absorption

If Applied Incorrectly

• Nutrients may not reach roots
• Gel benefits may be wasted
• Cost efficiency may reduce

General Principles for Applying Gel Fertilizers

Key Application Principles

• Apply gel fertilizer close to active roots
• Avoid surface broadcasting
• Ensure adequate soil moisture
• Apply only the recommended dose
• Prefer split application where possible
• Combine with irrigation when feasible

1. Application Methods for Cereal Crops

a) Basal Application at Sowing or Transplanting

Best for:

• Rice (transplanted)
• Wheat
• Maize

How to Apply:

• Place gel fertilizer 2–5 cm below and beside the seed or seedling
• Cover with soil immediately

Benefits:

• Strong early root development
• Uniform crop establishment
• Reduced nutrient loss

b) Side Dressing During Early Growth

Timing: 20–30 days after sowing

• Apply along crop rows
• Place near root zone and lightly cover with soil

• Matches peak nutrient demand
• Improves tillering and vegetative growth

c) Fertigation in Irrigated Cereals

Best for:

• Maize
• Wheat under sprinkler or drip systems

• Uniform nutrient distribution
• Lower fertilizer wastage
• Higher nutrient uptake

2. Application Methods for Pulse Crops

(Moong, Urad, Tur, Gram)

a) Basal Root-Zone Placement

• Apply in furrows before sowing
• Place 3–5 cm below seed level

• Strong root nodulation
• Better nitrogen fixation

b) Spot Application Near Plant Base

Timing: 25–35 days after sowing

• Apply small quantity near each plant
• Cover lightly with soil

3. Application Methods for Oilseed Crops

(Soybean, Groundnut, Mustard, Sunflower)

a) Furrow Placement at Sowing

• Apply along seed furrows
• Ensure contact with moist soil

b) Split Application at Critical Stages

• Vegetative growth
• Flowering / pod formation

4. Application Methods for Vegetable Crops

(Tomato, Onion, Potato, Brinjal, Chilli)

a) Root-Zone Application During Transplanting

• Apply near planting hole
• Mix lightly with soil

b) Drip Fertigation (Best Method)

• Precise nutrient delivery
• Reduced fertilizer requirement
• Higher yield and quality

c) Ring Application Around Plant

• Apply in a circular ring
• 5–8 cm away from stem

5. Application Methods for Fruit Crops

(Banana, Mango, Grapes, Citrus)

a) Basin Application in Orchards

• Apply in basins around trees
• Focus on active root zone

b) Drip Fertigation (Highly Recommended)

• Maximum nutrient efficiency
• Better fruit size and quality

6. Application Methods for Plantation Crops

(Sugarcane, Cotton, Tea, Coffee)

a) Trench or Band Placement

• Apply in trenches or bands
• Place near root growth zone

b) Split Application Across Growth Stages

• Matches nutrient demand
• Improves yield formation

7. Application in Protected Cultivation

(Greenhouse, Polyhouse, Hydroponics)

• Drip fertigation
• Controlled root-zone feeding
• Minimal wastage
• High yield consistency

Common Mistakes to Avoid

• Broadcasting on dry soil
• Applying far from root zone
• Overdosing
• Mixing incompatible fertilizers
• Applying without soil moisture

Best Time to Apply Gel Fertilizers

• Early morning or evening
• When soil is moist
• During active growth stages

Economic Benefits of Proper Application

• Lower fertilizer requirement
• Reduced labor cost
• Higher yield and quality
• Better return on investment

Conclusion

Gel fertilizers are powerful tools in modern farming, but their real strength lies in
proper application. Feeding the roots, not the soil ensures
higher nutrient efficiency, better yields, and sustainable profitability.
