Farmers feed rice paddies with probiotics to cut greenhouse gas emissions
Farmers feed rice paddies with probiotics to cut greenhouse gas emissions
2024-07-16
Probiotics aren’t just for gut health. In Yunlin County, they helped to reduce greenhouse gas emissions from growing rice. In an experiment by the local government and National Chung Hsing Univerity, probiotics were fed to rice fields. Initial results showed a reduction of 92% for methane emission and no negative side effects on yields.

The probiotics reduce methane emissions. It also allows us to use less nitrogen fertilizer. That’s very good for keeping the plants’ root systems healthy.
That’s right, rice fields are jumping on the probiotics trend. Besides improving the growth of the rice, the probiotics can help reduce their greenhouse gas emissions.

We hope to find a method that can cut down on greenhouse gas emissions without affecting yields.
The Yunlin County government is working to achieve net-zero emissions. To reduce emissions in the agriculture sector, it collaborated with National Chung Hsing University to promote probiotic use on eco-friendly farms in Dapi Township. As part of an experiment, probiotics were added to rice paddies. A section of the paddies were covered with an airtight lid to monitor emissions.

We found that adding probiotics to rice fields greatly reduces greenhouse gas emissions. We will continue with the experiment for our second rice crop.
Results are out for the experiment’s first rice crop. Methane emissions were reduced by 92% and nitrous oxide emissions by 80%. Experiments will continue over the second crop’s cycle, to verify that probiotics can indeed reduce harmful emissions.

不只顧腸胃! 稻作加入益生菌可減碳 二氧化碳減排效果顯著
2024-07-16
益生菌不只人可以吃，水稻也行，雲林縣與中興大學合作，在大埤鄉試驗，稻作生長期，加入益生菌，減少溫室氣體排放，結果出爐，發現二氧化碳總排放量大幅下降，農民也發現，可以減少氮肥使用，而且產量不受影響，達到雙贏。
農民揹著器具，走在田埂，對著稻作，來回噴灑，噴的不是農藥肥料，而是益生菌。

“益生菌主要把甲烷減少，還有一些氮肥，我們不用，用那麼多氮肥，等於肥料不用那麼多，對植物根系很健康”
沒聽錯，水稻跟上流行，也吃益生菌，除了讓水稻長得更健康之外，最主要目的，是要減少溫室氣體排放。

“我們希望是有一個方法，不但能夠減少溫室氣體排放，對產量又不會有影響”
雲林縣政府，積極推動淨零排放，為減少農業溫室氣體排放，和中興大學合作，在大埤鄉推動益生菌環境友善田，試驗稻作生產過程中，加入益生菌，再以密閉蓋罩，監測二氧化碳排放量。

“我們讓水稻田也吃益生菌，發現溫室氣體的排放，有大規模減低的作用，我們會在第二期稻作持續來實驗”
第一期稻作實驗，已取得初步成果，甲烷降低約92%、氧化亞氮降低約80%，未來二期稻作，將持續試驗，水稻吃益生菌，成了減碳愛地球妙方。
