Legume Cover Crops (LCC).

Planting legumes cover crop as ground cover is intended to cover the surface of the soil, so that the growth of weeds can be suppressed and reduce nutrient competition with palm trees later on.

Legume cover which often used in oil palm plantation are : Calopogonium Caerulium (CC), Pueraria Javanica (PJ), Calopogonium Mucunoides (CM), Centrosema Pubescens (CP), Mucuna Cochinchinensis (MC), dan Mucuna Bracteata (MB).

In general, the function of legume cover plants in oil palm plantations can be classified as plants that are generally useful (class A). Benefits of legume cover crop in the palm plantation is as follows:
a) Adding organic matter to improve soil structure.
b) Improve soil nutrients status, especially as nitrogen element fixation from the air.
c) Maintaining soil humidity, produce organic matter
d) Improving soil properties due to the land burning (land clearing)
e) Protecting the soil surface and reduce the danger of erosion, especially on steep ground.
f) Reducing the weeds maintenance cost.
g) To boost the growth of major crops and increase production

Type Calopogonium Mucunoides (CM )

Originating from Indonesia, It is a twinner and creeper with tolerance for poor soils. The legume cuts off during dry months. It is a prolific seeder.

CM is a vigorous, creeping, twining or trailing, short-lived perennial herb. It belongs to the Family Fabaceae (alt. Leguminosae). Calopogonium mucunoides is a recognized valuable cover crop which has excellent soil erosion control and soil fertility improvement activities. Seed rate is 3-4.5 kg per ha.

- Rapid seed establishment
- Fast initial growth
- Wide edaphic adaptation

Type Centrosema Pubescens ( CP )

Plants that grow slowly and are resistant to various circumstances.
