Yield, Potassium Content and Root Distribution of Alfalfa and Bromegrass Grown Under Three Levels of Applied Potash in the Greenhouse1

- Milo B. Tesar2
In greenhouse trials, significant increases in yield and K absorption of alfalfa and bromegrass were obtained as applied K increased. Yield response to fertilizer K was less marked with soil containing more available soil K. Total production of bromegrass was half that of alfalfa, but the quantities of K removed were about equal. The change in several extractable fractions of soil K was directly related to the root distribution pattern of the forage.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
