Resistance, cold resistance, drought resistance, disease res
Enhance the stress resistance of crops, and have obvious effects on cold resistance, drought resistance and disease resistance. The fulvic acid can effectively regulate the closure of plant stomata, and can automatically close the stomata of the epidermis under drought conditions, reducing the evaporation of water and achieving drought resistance. At the same time, fulvic acid can promote the ...

Ocean pH: Then, Now, and Future
Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of atmospheric carbon dioxide (CO2) as water and air mix at the water’s surface. In an effort to better understand the historical evolution of ocean acidification, the Environmental Visualization Laboratory at NOAA has developed an Interactive Map that shows pH data from 1861 to present day, ...

Trees could be used to monitor air pollution simply and cheaply
It may be possible to use trees to monitor levels of air pollution in cities, new research suggests. A Belgian study found evidence that leaves of urban trees change both chemically and physiologically when exposed to different levels of air pollution. If these changes are carefully quantified, trees could provide cheap and widespread ‘bio-indicators’, the study’s authors ...
