Redox measurements in paddy soils in South Korea
The company C&H is our highly experienced and valued distributor in South Korea (www.candh.co.kr). They are specialized in environmental and agrological monitoring equipment. Last summer and autumn, they supported a scientific study in which the Redox potential in paddy soils (rice fields) was measured with our soil Redox probes (Redox probes – SWAP instruments). When the paddy soil was dry, the Redox potential was approximately 600 mV. Upon flooding, the redox conditions underwent rapid and large changes: from oxic to anoxic conditions. During the anoxic conditions, methane was formed. Methane is a powerful greenhouse gas, with a Global Warming Potential more than 80 times greater than that of carbon dioxide (Facts about Methane | UNEP – UN Environment Programme). By controlling the water level in rice fields in a smart way, methane emissions can be reduced significantly. This can help limit global warming.
