Estimation of leaf water potential by thermographic and spectral measurements in grapevine [PDF]

RIA: Revista Investigaciones Agropecuarias, 2011
Leaf water potential (ΨL) is a useful variable for the water status assessment of crops. The pressure chamber is the current method for its measurement, but has the disadvantage of being too slow and impractical when to asses an important number of ...

Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Structural and Rheological Properties of Chitosan‐Biochar Composites Prepared With Waste Biomass‐Derived Biochar

Polymer Engineering &Science, EarlyView.
Chitosan dispersions containing biochar derived from vine pruning residue showed increasing shear stress and improved thermal stability with loading. Flow behavior was described by the Bingham plastic model in all cases. These results support the valorization of agricultural waste in functional biopolymer formulations.
