conditions of the district, a good understanding of the principles
of agriculture without irrigation under a low rainfall, and a
vigorous application of these principles as adapted to the local
climatic conditions will make dry-farm failures a rarity.






CHAPTER V

DRY-FARM SOILS





Important as is the rainfall in making dry-farming successful, it is
not more so than the soils of the dry-farms. On a shallow soil, or
on one penetrated with gravel streaks, crop failures are probable
even under a large rainfall; but a deep soil of uniform texture,
unbroken by gravel or hardpan, in which much water may be stored,
and which furnishes also an abundance of feeding space for the
roots, will yield large crops even under a very small rainfall.
Likewise, an infertile soil, though it be deep, and under a large
precipitation, cannot be depended on for good crops; but a fertile
soil, though not quite so deep, nor under so large a rainfall, will
almost invariably bring large crops to maturity.
