Characteristics of the root exudate release system of typical plants in plateau lakeside wetland under phosphorus stress conditions

open access: yesOpen Chemistry, 2020
In this study, the root exudates of wetland plants, Pistia stratiotes, black algae, and Cyperus alternifolius, exposed to six phosphorus concentration gradients (0, 0.2, 1, 5, 10, and 20 mg/L) were characterized.

Measuring very negative water potentials with polymer tensiometers: principles, performance and applications [PDF]

open access: yes, 2009
In recent years, a polymer tensiometer (POT) was developed and tested to directly measure matric potentials in dry soils. By extending the measurement range to wilting point (a 20-fold increase compared to conventional, water-filled tensiometers), a ...
