CONTROL OF SOIL MOISTURE
The truth that moisture is a leading
factor in soil productiveness is evidenced by the value of straw and
similar material as a mulch. A covering of straw around trees in an
orchard, or bush fruits, or such plants as the potato, may give better
results than an application of fertilizer when no effort is made to
prevent the escape of water. People so situated that little attention
can well be given to the fruit and vege
able garden obtain good results
by replacing tillage with a substantial mulch that keeps the soil
mellow, prevents weed growth, and retains an abundant supply of water.
In grain-producing districts where all the straw is not needed as an
absorbent in the stables its use as a mulch on thin grass lands, or
wheat-fields seeded to grass, is more profitable than conversion into
manure by rotting in a barnyard. The straw affords protection from the
sun, and aids in the conservation of soil water, when scattered evenly
in no larger amount than two tons per acre, and a less amount per acre
has value. The sod is helped, and as the straw rots, its plant-food
goes into the soil.
