: A mature rubber tree usually provides its maximum latex yield around 13 years after planting , or 7 years after tapping begins.
: Trees reach yielding maturity at approximately 6 to 7 years old, or when they reach a trunk girth of about 150 mm.
: Research on mature rubber fertilization emphasizes maximizing benefits during high-price periods while avoiding unnecessary costs during low-price periods to maintain sustainability.
: Once processed, mature rubber materials are subject to thermal oxidation and physical aging. This degradation changes the crosslink density, increasing material hardness and reducing elasticity over time. Key Reference Articles
