Classification

Type of Soil

Agricultural Potential - Remarks

1^st

LATOSOLS

Generally Good: Soil needs protection from erosion and fire. Composition phosphate and organic fertilizers (Rock phosphate)

1^st

ALLUVIALS

Good Soil: Potential Acidity: Recommend colmatage canals. Cultivation concordance with the water regime. Green manure, phosphate, and potash (avoid the use of sulphate fertilizers)

1^st

BROWN ALLUVIALS

Rich Soil: Need phosphate and potash. Flood protection

1^st

REGURS

Rich Soil:

• Basaltic regurs: Cultivation to be encouraged
• With irrigation, rice, sugar cane, pineapple, banana, seasonal crops etc.
• Calcic (Limestone) regurs: Corn, Beans, Banana, Cotton, Sugar cane

2^nd

BROWN HYDROMORPHICS

Very Good Rice Soil: Arboriculture on higher elevation and other crops. String beans: cash crop in the rice paddies.

2^nd

LACUSTRINE ALLUVIALS

Rich Soil: Need phosphate for a better yield. Possible improvement irrigation

3^rd

COSTAL COMPLEX

Protection against salt water. Good soil, but expensive engineering.

3^rd

RED YELLOW PODSOLS

Poor: Structure easily destroyed. Soil rapidly leached, lacking fertilizes elements.

3^rd

CULTURAL HYDROMORPHICS

Graded Rice Paddies: Need organic and chemical fertilizing. Rotation with market gartering crops and beans.

3^rd

GRAY HYDROMORPHICS

Better Soil than Cultural Hydromorphics: Scattered in distance areas. Difficult access planting. 80% forests in depression and hollows.

3^rd

PLANOSOLS

Soil Good: Enough for rice when prepared and irrigated.

4^th

PLINTHITIC HYDROMORPHICS

Must remain under forest.

4^th

ALUMISOLS

Toxid Soil: Need organic fertilizers, rock phosphate and urea for rice. Line and drainage necessary for other crops.

4^th

ACID LITHOSOLS

Optimum Use: Forestry. Recommended national park on west side, mountainous areas. Livestock in open forest area.

4^th

BASIC LITHOSOLS

Optimum Use: Forestry, to be use for forest reserve.

4^th

PLINTHITE PODZOLS

Soil Poorer: Low agriculture potential. Covered with open forest. Reserve for extensive for livestock breeding. Cultivation not advisable.
