The palm oil industry
The palm oil industry often makes news for harming tropical forests and affecting orangutans. However, the economies of many tropical nations rely heavily on palm oil. Many people rely on it for their livelihood, including small farmers. Also, without cheap palm oil, many commonplace items would cost more. The Roundtable for Sustainable Palm Oil was established in 2004 by the WWF (World Wide Fund for Nature) in collaboration with industry partners. But they haven’t provided clear advice about how much herbicide or fertilizer should be used. The available research is insufficient. As a result, oil palm producers have been hesitant to adopt new techniques that could eventually result in lower yields.
In 2016, an intriguing event occurred. In Jambi province, Sumatra, the German-Indonesian Collaborative Research Center, also known as EFF or TS, began an experiment on an oil palm plantation. They collaborated with PTPN6, the national company of Indonesia. Two levels of fertilizer were established by the researchers: low (to replenish what was removed during harvesting) and high (roughly twice the typical amount used in the industry). They also looked at weed control methods—either using machinery or common herbicides like glyphosate. The teams studied not only the oil palms but also the soil & biodiversity, checking things like microbial biomass, bird activity, soil health, and how well the palm leaves were growing.

“Two years after we started testing our methods, we couldn’t see a drop in yield,” says Kevin Darras from the Agroecology Group at the University of Göttingen. “Actually, profits went up because we spent less on fertilizer.” The effects on soil quality were either tiny or even positive! Some biodiversity measures showed improvement with mechanical weed removal because more plants grew—this helped animals too!
- EFF or TS plans to keep an eye on these experimental plots for four more years. “These results are really encouraging,” says Darras. “But it’s important to keep going with our research. It can take years for oil palms to respond fully to changes!” Future studies will look at long-term findings, greenhouse gas emissions, & create models to help guide everyone involved with clear recommendations.
