Crop Type Application Rate (kg/ha) Recommended Timing Application Method
Vegetables (e.g., tomatoes, peppers) 200-300 At planting and mid-growth Soil application and side-dressing
Lawns and Turf 50-100 Early spring and late summer Broadcast and water-in
Fruit Trees 150-250 Pre-bloom and post-harvest Soil application around drip line
Flowers and Ornamentals 100-150 At planting and monthly during growing season Soil application or foliar spray

It is crucial to avoid over-application, as excessive fertilizer can lead to nutrient runoff, environmental pollution, or plant damage.

Considerations for Optimal Use

To maximize the effectiveness of 16-16-16 fertilizer, consider the following:

  • Soil Testing: Conduct soil analysis to determine existing nutrient levels and pH before applying fertilizer.
