China

China is also interested in dry-farming.  The climate of the drier portions of China is much like that of the Dakotas.  Dry-farming there is of high antiquity, though, of course, the methods are not those that have been developed in recent years.  Under the influence of the more modern methods dry-farming should spread extensively throughout China and become a great source of profit to the empire.  The results of dry-farming in China are among the best.

These countries have been mentioned simply because they have been represented at the recent Dry-farming Congresses.  Nearly all of the great countries of the world having extensive semiarid areas are directly interested in dry-farming.  The map on pages 30 and 31 shows that more than 55 per cent of the world’s surface receives an annual rainfall of less than twenty inches.  Dry-farming is a world problem and as such is being received by the nations.
