Phosphorous Fertilizer Where phosphorous fertilizer was applied to this field, regardless of the amount or method of application, the alfalfa was much taller (8-10 inches compared to 15-18 inches), and it had many more stems per square foot. In addition the color was much better and the leaves were larger. Yield was also significantly improved with added phosphorous. *Picture taken on tour in Washita County on April 16, 1998. |
