Almond Productivity as Related to Tissue Potassium

"Nutrient deficiency may conceivably reduce potential future yields (in terms of flower/fruit number) by limiting growth of new shoots and spurs, by reducing the productivity of existing spurs, and by reducing the quality or quantity of floral differentiation." - A 2001 Better Crops article by Edwin J. Reidel, Patrick H. Brown, Roger A. Duncan, and Steven A. Weinbaum.
