InfoSAWIT, JAKARTA - The soil researcher from Malaysia, S Paramananthan from Pram Agricultural Soil Survey (M) Sdn. Bhd., mentioned, the wetland in Asia and in Europe is different. The soil in wetland in Europe is made of grass, while the soil in wetland in Asia is mostly made of wood because Asia has many wood (forests) and trees.
So, Pramananthan or famously called as Param said, the wetland in Europe is categorized the same as the wetland in Asia. “Similizing the category of the wetland is not right,” Param said.
So, it is normal that the wetland cultivation for paalm oil has some problems, such as, if the base soil in the wetland is full of wood, it will be difficult to cultivate palm oil. “Planting in wetland which is full of wood will be a problem,” he recently said in Jakarta.
In addition, the wood could not lifted to the surface. This will be more difficult if it happens in the wetland within the hard wood. This will make more losses to develop the wetland.
So, cultivating wetland needs good preparation within the previous scientific researches. Param said, cultivating in wetland does not limit to its depth.
It is revealed after Param Agricultural Soil Survey (M) sdn Bhd., did researches about the cultivation in 1,5 meter depth and 3 meter depth.
From the research, it is known that the depth of the wetland does not effect the cultivation result. “Based on our researches, from the students of Doctoral Programme in Malaysia, we compare the palm oil cultivation in the 1,5 meter depth and more than 3 meter depth. And the results were the same,” he said.
It is clear that the wetland could be cultivated in different kinds of depth. But palm oil cultivation in the wetland will find some problems if the base of the soil in the wetland has hard wood because it has something to do with the root of the palm oil tree.
Param ensured, advantaging wetland to cultivate the areas will have no problems. But, he also admitted, until now many foreign researchers, namely from the western forbid the planting in the wetland.
Actually, the wetland could not be categorized in the same way because wetland has its kinds and different category. Param, at least, noted, there are 9 groups of wetland, such as, kinds of Fibric, Hemic, Sapric, and other. “At least, there are nine groups of wetland,” he said.
Of nine kinds or groups of wetland, he continued, there are three kinds of them which could not be cultivated because the three have hardest wood in the base.
If the fibric and sapric are compared, the results in sapric will be better because the productions are more than it in fibric. The green house effect is less than it in fibric, and the area fertility is higher too. If using the fibric wetland, there will be more green house effects, more fund to cultivate it, but less productivity.
He continued, the mistakes in cultivating palm oil in wetland are, many businessmen cultivate palm oil in wetland by making the deep drainage. Actually it is enough to make 50 cm depth trench from the surface of the soil.
This is thought to reduce the evaporation of the green house effect in the wetland, including to slow down the subsidence. “The wetland in Malaysia and Indonesia is almost the same. We have mapped the wetland in Southeast Asia,” Param said. (T2)
