1. What is Trees Per Hectare Calculation?

The trees per hectare calculation determines the optimal planting density for agricultural or forestry projects. It helps farmers and foresters plan their plantations efficiently to maximize yield while maintaining healthy growth conditions.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• 10000 — Number of square meters in one hectare
• Row spacing — Distance between rows in meters
• Tree spacing — Distance between trees within a row in meters

Explanation: The calculation divides the area of one hectare (10,000 m²) by the area occupied by each tree (row spacing × tree spacing).

3. Importance of Tree Density Calculation

Details: Proper tree density affects sunlight exposure, nutrient availability, air circulation, and ultimately the health and productivity of the plantation. It's crucial for both commercial plantations and reforestation projects.

4. Using the Calculator

Tips: Enter row spacing and tree spacing in meters. Typical values range from 1-10 meters depending on tree species and purpose. Both values must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What's the ideal tree density?
A: It varies by species - fruit trees might need 100-400 trees/ha, while timber species might be planted at 800-1600 trees/ha.

Q2: How does spacing affect tree growth?
A: Closer spacing increases competition, resulting in taller but thinner trees. Wider spacing allows for broader canopies and thicker trunks.

Q3: What's the standard spacing in the Philippines?
A: For coconut palms, 8×8 meters (156 trees/ha); for mangoes, 10×10 meters (100 trees/ha); for mahogany, 3×3 meters (1,111 trees/ha).

Q4: How to account for sloped terrain?
A: On slopes, reduce row spacing slightly to maintain soil conservation while adjusting tree spacing to maintain density.

Q5: When should I use triangular instead of square spacing?
A: Triangular planting allows 15% more trees per hectare and is often used in high-density plantations.
