Chapter 1: Fertilizer Fundamentals
Master the essential concepts of plant nutrition and fertilizer science
Understanding NPK
Nitrogen (N)
Promotes vegetative growth, chlorophyll production, and overall plant vigor. Essential for leaf and stem development.
Phosphorus (P)
Crucial for root development, flowering, and seed production. Enhances early plant establishment.
Potassium (K)
Improves disease resistance, water regulation, and fruit quality. Essential for plant stress tolerance.
Common Fertilizer Types
Urea (46-0-0)
Highest nitrogen content fertilizer, ideal for vegetative growth
• 46% Nitrogen
• Quick-release
• Cost-effective
DAP (18-46-0)
Perfect starter fertilizer with nitrogen and phosphorus
• 18% Nitrogen
• 46% Phosphorus
• Ideal for planting
MOP (0-0-60)
Pure potassium source for fruit development and disease resistance
• 60% Potassium
• Highly soluble
• Quality enhancer
Chapter 2: Soil Testing & Analysis
Learn how to assess your soil and determine nutrient needs accurately
Soil Testing Process
Sample Collection
Collect soil samples from multiple locations at proper depth
Laboratory Analysis
Professional testing for pH, nutrients, and organic matter
Result Interpretation
Understanding nutrient levels and pH implications
Recommendation Development
Create targeted fertilizer program based on results
Quick Assessment Guide
When soil testing isn't available, use these visual indicators:
Key Soil Parameters
pH Level (6.0-7.0 ideal)
Affects nutrient availability and microbial activity
Organic Matter (3-5% optimal)
Improves soil structure and nutrient retention
Phosphorus Levels
Critical for root development and flowering
Potassium Levels
Essential for disease resistance and quality

✓ Good for nitrogen
Foliar Application
Spray application directly on leaves
✓ Quick nutrient uptake
✓ Ideal for micronutrients
✓ Corrects deficiencies fast
Timing Guidelines
Split Application Schedule
Pre-Planting (40%)
All P, 40% N, 50% K
Mid-Season (35%)
35% N, 30% K
Late Season (25%)
25% N, 20% K

Troubleshooting Guide
Yellowing Leaves
Usually nitrogen deficiency - apply urea
Poor Root Development
Phosphorus deficiency - increase DAP
Disease Susceptibility
Potassium deficiency - apply MOP
Fertilizer Burn
Over-application - water thoroughly and reduce rates
Poor Nutrient Uptake
pH issues - test and adjust soil pH
