Phosphorus Fertilizer Applied

This photo is a plot of alfalfa growing where phosphorus was applied to phosphorus-deficient soil.  A few feet away where phosphorus was not applied plants were much shorter.

Most of the stems where no fertilizer was applied are about 13 inches tall; whereas, the stems where fertilizer was applied are about 22 inches tall. No other clear symptoms of phosphorus deficiency were apparent in the field.
