An experiment testing which green manure was suitable to recover decontaminated farmer’s land in Yamakiya. Left - soil is light colored and contains low carbon. Right- Our experimental plots with green manures grown. Rye was one of the most prospective species suitable for their climate in terms of aboveground biomass growth.

Common reed occupies a fallow land. This area used to be cultivated for rice but seems not managed by anyone now.

A small-sized experiment to see the effects of fertilizer and cow manure application on green leaf vegetable plants. Cow manure was helpful to increase plant growth. Chemical fertilizer in Yamakiya decontaminated soil improve plant growth but less than fertilized, healthy Japanese soil. ....

Yellowstone's Lower Geyser Basin may have looked much different 4,000 years ago


About 3,800 years ago Yellowstone National Park’s Lower Geyser Basin underwent a significant environmental change.
Montana State University paleoecologist Christopher Schiller and his colleagues have analyzed pollen, algae and chemicals in a 2018 sediment core from the basin’s Goose Lake. They linked it to research by other scientists in the region to document an increase in local hydrothermal activity that led to the open landscape tourists see today.
The Goose Lake/(Lower Geyser Basin) research is important because it ties together our understanding of climate, geology, vegetation, and limnological history for the first time, wrote Cathy Whitlock, MSU professor of earth sciences, in an email. It reminds us that Yellowstone is not just an ecosystem but a geo-ecosystem, where the dynamics are governed by both geological activity and climate.   ....

The drive lasted about 33 minutes, propelling the rover forward by four metres, where it then turned to the left by 150 degrees and backed up 2.5 metres into its new temporary parking space
NASA’s latest Mars rover, Perseverance, performed its first test drive on the Red Planet, covering a distance of about 6.5 metres across the Martian landscape, a “major milestone” before it begins its science operations.
The drive lasted about 33 minutes, propelling the rover forward by four metres, where it then turned to the left by 150 degrees and backed up 2.5 metres into its new temporary parking space, the American space agency noted in a statement. ....
