Written on verso: The one to his right received 200 pounds of 16-5-5 fertilizer per acre, applied in rows when planted. The six rows to his left received no fertilizer. This field of several acres was drained in 1929 and two tons of lime per acre added. The entire field was planted, six rows with fertilizer and six rows without, all across the field and each plot shows as clearly as the one represented here the effect of fertilizer.
