The Way to Press the Loss of Nitrogen in Palm oil Plantation



The Way to Press the Loss of Nitrogen in Palm oil Plantation

InfoSAWIT, BALI – Nitrogen is kind of hara that is needed when cultivating palm oil plantation. The issue is that the climate change has made Nitrogen loss and in the end, the quality of palm oil trees is not so good.

The loss of Nitrogen makes the planters spend additional costs to get Nitrogen. “Just focus to the cycle of Nitrogen because the global disturbance of Nitrogen cycle is the big challenge to face,” a researcher of CIRAD, Lenaic Pardon said in a discussion in International Conference of Oil Palm and Environment (ICOPE) where InfoSAWIT did attend too.

He said, for palm oil plantation industries, the loss of Nitrogen makes additional cost. Though there were efforts to get Nitrogen back from the soil, the fluxeskeeps happening. In the empty fruit bunch, the decomposition of Nitrogren fluxes is complex, it happens in time and space. Before he did the research, actually, there were some models but they are not comprehensive yet.

In his research, Pardon used three approaches, such as, literature, comparison model, and sensitivity analysis. The results, there was high internal fluxes among the compartment in the plantation. He also found that the Nitrogen washing was the factor of its loss, reaching 80%.

Besides he also did the other research to know the effect by adding Nitrogen when planting palm oil trees. The result was that it had something to do with the environment.

Besides Pardon used INDIGO approach by identification phase of the user, the loss of Nitrogen in the score, testing the scenario to know and see the factors. The last was that he validated everything and as a matter of fact, there were limits in the validation process.

The result of the study showed that Nitrogen washing depends on the time. The research was done when the legume grew in palm oil plantation. In average, the release of Nitrogen would be 60 kilogram per year and its would decrease when the palm oil trees are 12 years old. (T1)
