Overall the Indonesian islands only consist of ultisol or red yellow and peat that have average high acidity, so it is not good for growing plants, "he said, in Padang on Sunday .
He mentions that although there is a volcano on Sumatra Island and has fertile soil, but the whole is more dominated ultisol and peat. Ultisol soil is scattered along mountain ranges of mountains, while peat on the west coast and east of Sumatra.
Later in Kalimantan and Papua are also dominant peat soils and a small part of ultisol. The same is true in the predominantly Sulawesi region of Sulawesi, and partly by ultisols.
While on the island of Java and Bali to Nusa Tenggara region dominated by active volcanoes, the type of soil that is widely found that Andisol, he said. "Not fertile does not mean can not be planted, if given the treatment of the soil technology will produce abundant production," he said.
According to him, despite having infertile soil, the production of various commodities in Indonesia is quite high. This means that the plants that grow in the area have been able to adjust for life.
However, he said, if given the treatment of technology such as liming or adding natural fertilizer.
Soil will be fertile and production will increase multiply, he said. "When it's like throwing a stick into a plant is a reality," he said.
Meanwhile,
the Agricultural Research and Development Agency of West Sumatera through Ismon researchers mention that the evidence is not fertile soil, which began the number of farmers in Indonesia divert livelihoods from paddy fields or farming to gardening.
This happens due to the rice fields it has to be fertilized in large quantities, so it costs a lot. With gardening, for example, oil palm or rubber need not require much fertilizer.
Therefore, both plants are very suitable to grow in infertile soil types such as ultisols and peat, he said
