Always disk the land in early spring, to prevent evaporation.  Follow the disk with the harrow.  Harrow, or in some other way stir the surface of the soil after every rain.  If crops are on the land, harrow as long as the plants will stand it.  If hoed crops, like corn or potatoes, are grown, use the cultivator throughout the season.  A deep mulch or dry soil should cover the land as far as possible throughout the summer.  Immediately after harvest disk the soil thoroughly.

Destroy weeds as soon as they show themselves.  A weedy dry-farm is doomed to failure.

Give the land an occasional rest, that is, a clean summer fallow.  Under a rainfall of less than fifteen inches, the land should be summer fallowed every other year; under an annual rainfall of fifteen to twenty inches, the summer fallow should occur every third or fourth year.  Where the rainfall comes chiefly in the summer, the summer fallow is less important in ordinary years than where the summers are dry and the winters wet.  Only an absolutely clean fallow should be permitted.

The fertility of dry-farm soils must be maintained.  Return the manure; plow under green leguminous crops occasionally and practice rotation.  On fertile soils plants mature with the least water.

Sow only by the drill method.  Wherever possible use fall varieties of crops.  Plant deeply—­three or four inches for grain.  Plant early in the fall, especially if the land has been summer fallowed.  Use only about one half as much seed as is recommended for humid-farming.

All the ordinary crops may be grown by dry-farming.  Secure seed that has been raised on dry-farms.  Look out for new varieties, especially adapted for dry-farming, that may be brought in.  Wheat is king in dry-farming; corn a close second.  Turkey wheat promises the best.

Stock the dry-farm with the best modern machinery.  Dry-farming is possible only because of the modern plow, the disk, the drill seeder, the harvester, the header, and the thresher.

Make a home on the dry-farm.  Store the flood waters in a reservoir; or pump the underground waters, for irrigating the family garden.  Set out trees, plant flowers, and keep some live stock.

Learn to understand the reasons back of the principles of dry-farming, apply the knowledge vigorously, and the crop cannot fail.

Always farm as if a year of drouth were coming.

Man, by his intelligence, compels the laws of nature to do his bidding, and thus he achieves joy.

“And God blessed them—­and God said unto them, Be fruitful and multiply and replenish the earth, and subdue it.”
