Purdue Landscape Report: Water covers approximately 71% of Earth’s surface, yet only 3% of the 326 million cubic miles of water on the planet is suitable for growing crops, such as trees. It can be ...

Our approach is predicated on the knowledge that precipitation δ 2 H and δ 18 O values (see Methods for definitions) co-vary along a regression line with a δ 2 H/δ 18 O slope of eight (this is the ...

Proper irrigation is very important for plant health. Too much or too little can both be damaging to plants. I’ll begin with a description of a process called evapotranspiration. This process combines ...

The Amazon is the world’s largest tropical forest, home to unmatched biodiversity and one of the planet’s longest rivers. Besides the Amazon River, the Amazon rainforest also features “flying rivers:” ...

The ability of trees to cool by transporting water from their roots to the leaves has been known for centuries. But as Stephen Ornes discovers, the principles of transpiration are also inspiring ...

Most of the water that enters a plant will exit the leaf into the atmosphere. This provides a continuous stream of water which is known as the transpiration stream. Surface area (not an environmental ...

The leaves of trees process massive amounts of water – worldwide, four times the volume of Lake Superior moves from the soil and is turned into water vapor by plants every year. With rising levels of ...

Watch this video to discover how plants transport water in the xylem and sugars in the phloem to stay healthy. As water travels through the xylem in the stem and leaf, it is being replaced by water ...
