The screaming tires.
The screaming tires must be based on principles that will have to be when tapping latex at most the least damaged shell to cut 25-30 years.
And most cost-effective
The size of the open slit.
The size of the available open source must be screaming the perimeter not less than 50 cm measured at a height of 150 cm from the ground.
Open source is the first time the number of screaming tires, with open slit in the Park, more than half of the entire Park.
Rubber trees can track open, screaming for the first time at the height from the ground level 50, 75, 100, 125, or 150 cm at one but if I turn on a low, screaming to get greater productivity.
