Potassium (K) deficiency in wine grapes results in reduced vine growth, premature leaf drop, and yield and color loss. K can be fixed in the interlayer of clay minerals in a process called K fixation, which leads to high spatial variability in soil K

Expanding the Paradigm: The influence of climate and lithology on soil phosphorus

Autor: Stewart G. Wilson, Randy A. Dahlgren, Andrew J. Margenot, Craig Rasmussen, Anthony T. O'Geen

The fate of phosphorus (P) during pedogenesis has been historically conceptualized (Walker-Syers model) with time as the primary controlling state factor. Herein, we demonstrate that both climate and lithology exert a strong and interacting influence

Defining and Managing for Healthy Vineyard Soils, Intersections With the Concept of Terroir

Autor: Stewart G. Wilson, Charlotte Decock, Cristina Lazcano

Publikováno v: Frontiers in Environmental Science, Vol 8 (2020)

The use of sustainable soil management practices is becoming common in wine growing regions around the world in response to an increased awareness of the value of soil health to maintain environmental quality, crop yield, and grape quality. In spite
