Applications of Phosphorus Fertilizer

The plot on the right is alfalfa growing on phosphorus deficient soil. The plot on the left (a few feet away) shows where phosphorus was applied.

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.
