Plant Population Calculator
Professional agricultural plant population calculation tool that helps farmers and agricultural technicians determine optimal planting density. Supports multiple crop types, planting patterns, and spacing configurations to maximize field coverage and optimize crop yield potential.
What is Plant Population?
Plant population refers to the number of plants growing within a specific area—typically measured per acre or per hectare. It's calculated based on how far apart the plants are spaced both within a row and between rows. Understanding plant population is crucial in crop management because it directly influences competition for nutrients, sunlight, and water.
Planting Density Formula
Basic Formula:
Plants per hectare = 10,000 ÷ (Row spacing × Plant spacing)
* Spacing measurements should be in meters. For triangular planting patterns, multiply result by 1.15 for better accuracy.
Optimal Density Guidelines
High Density: Leafy greens (lettuce, spinach)
Moderate to High: Root crops (carrots), Grain crops (corn, wheat)
Low Density: Bushy or vining crops (zucchini, pumpkins)
