Estimation of Available Soil Potassium from Plant Analyses1
- M. W. Phillips and
- S. A. Barber2
Results from greenhouse and field experiments indicate that total potassium uptake is a more precise measurement of available soil potassium than is the percent potassium in the whole plant or in the sixth leaf. Total uptake of potassium varied less with variations in nitrogen, phosphate and plant weight than did percent composition.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
