Palm Oil Cultivation in the Tidal Areas



Palm Oil Cultivation in the Tidal Areas

InfoSAWIT, JAKARTA – The tidal areas actually have potential to be palm oil areas but the main issues still block the development, namely about the cultivation, technical net-culture, and infrastructures.

It needs the right designs, cultivations, advantages, and technology implementations about the water and the soil (land). It is different from the mineral areas. The tidal areas have unique characteristic. That is why it needs specific management because of the different water volume every time.

It needs to control the drainage based on the plantation needs and should function to prevent the over drainage, to avoid the over oxidation of pyrite.

From what InfoSAWIT got, it is important to cultivate palm oil in the tidal by knowing the condition of the areas to know what fertilizer could be applied to. Know the condition of the areas and kinds of fertilizer in the first place. This has something to do with the efficiency and productivity.

Based on the ingredients in the pyrite, there are two kinds of soil in the tidal areas, they are, typic sulfaquent and sulfic endoaquept. The difference of the both is in the layers of the pyrite.

The typic sulfaquent has about 50 centimeter – layer from the soil surface but the sulfic endoaquept has about 100 centimeter – layer.

In general, palm oil could grow and have better production if planted in deeper layer of pyrite from the soil surface.

The growth and the production are determined by the quality of the culture technic, namely in the water management. The tidal areas that have bad - open and close irrigation system could make the water unstable because the water could be more than 50 centimeter from the water surface, but could be 1,5 meter less (from the soil surface).

In general, the decreasing water (from the soil surface) is the issue. The height of the water should be stable about 75 centimeters in the areas. If it is not, the pyrite in the soil would be the oxidation and toxic to the plantation. (T2)
