The Benefits of Thinning for Jabon Plants

During the maintenance period, Jabon plants need to be thinned. Thining Jabon plants is an activity to reduce the number of trees per hectare.

This reduction aims to provide wider growing space for the trees that are maintained.

Reduction is carried out on plants that are attacked by pests and diseases. In addition, plants with poor morphology and stress trees also need to be reduced. The end result of thinning is a plant or tree with high productivity.

Trees that are maintained or not reduced are trees that have straight trunks, are healthy, and large in size. Thus, it is hoped that at the end of the cycle or harvest, farmers can get high profits.

Thinning rotation is very beneficial for soil quality. The first thinning is done when the plant is three years after planting. At that age the Jabon plant is expected to have grown to a minimum diameter of 25 cm so that the thinning wood has economic value. Furthermore, the next round of thinning is adjusted to the needs.

In the Philippines, thinning of Jabon plants is carried out since the plants are 5 years old. The results of the dilution are used for pulp materials. While the materials used to produce sawn wood or carpentry wood are obtained from thinning when the plant is seven years old.

Jabon plant thinning needs to be done for planting with initial spacing of 3 m × 1 m, 3 m × 2 m, and 3 m × 3 m. This thinning can provide optimal growth on trees with good morphology.

There are two thinning methods that are often used in community forests. First, thinning to remove trees that grow badly, attacked by pests and diseases, and adjust the spacing. Second, thinning known as delih or deneng to get an initial income.

Jabon plant thinning needs to be done immediately when the plant leaves have interacted too deeply. Late thinning can cause stunted Jabon tree diameter growth. You can't see all the plants growing if the crowns are interlocked as this will only hinder the growth of the jabon.
