An Over-dose and its Remedy
The whole of the plot of land shown in the illustration has been manured to jxcess with
ammonium salts. As a result the crop of barley sown on the land is a complete failure,
except on the left-hand part of the plot, where the crop has been restored by the addition
of lime.
