UNDERWOOD GROWER WINS IN BATTLE WITH OLD ORCHARDS AND DRY LAND
(Ed. note - The following article, reprinted from the Western States Reclamation
Journal, should prove of interest to News readers, for it relates how old
orchards, further handicapped by lack of moisture, may be rejuvenated.)
In the bustling Underwood Hill farming community, 3½t
miles west of White Salmon, Wash., an alert fruit grower, Harry Card, has
gained recognition for his development of land conservation practices in
one of the toughest testing grounds in south central Washington state.
Since Card took over his 145-acre steeply sloping, dry
land ranch in 1936, he has been waging a hard battle to overcome heavy soil
and fertility losses and declining crop yields. But he has now won the victory.
Card's program of conservation farming practices showed
marked gains this last fall when his apple and pear crops reached a new high
in production, while soil and fertility losses were reduced sharply.
Marked Increase In Yield
Some idea of the worth of the measures employed by Card
can be summed up by a comparison of the 10,000 boxes of fruit he harvested
from 37-year-old trees with the 3,810 boxes produced in 1943 on the same
acreage. That is a very marked increase.
Unprotected farm land on Underwood Hill is made to order
for erosion, with this steeper slopes averaging from 20 to 25 percent pitch.
Most of the 40-inch annual rainfall occurs between October and May. Under
such weather conditions, Skamania county farmers try to use soil and water
conservation practices which will control their winter water problems and
save summer moisture.
When Card purchased his dry land orchard 11 years ago,
he was aware that his trees had passed their harvest peak of 20 or 30 years.
Crop yields of his 37-year-old stands had already started to skid.
"My apple and pear trees," Card explains, "quit producing
almost as soon as I moved on the ranch. My orchard was thirsting for water
and I was losing layers of fertile topsoil during every rainy season. I figured
it was time for a change."
Conservation Service Helps
Card combined soil conservation and horticultural practices
to improve in his box score. He began by putting the soil-holding and
moisture-saving practices recommended by soil technicians of the White Salmon
office of the U.S. Soil Conservation Service. He took prompt action, too,
on a tree-thinning plan outlined by J.I Griner, formerly Washington state
supervisor of horticulture.
Griner's plan called for cutting out half of the fruit
trees in the 30-acre orchard. The remaining trees thus received an extra
supply of moisture. Card pulled out every other diagonal row and opened the
distance between trees from 27 to 34 feet. He also carried out a thorough
job of spraying and pruning his thinned orchard.
With more moisture to go around and added "growing" room,
both apple and pear trees showed a steady pick-up in yields. The 10,000 boxes
counted this past season are certainly a sign that Card's trees are again
busy on the production line. And before many harvest seasons are past, the
output is expected to top the high of 11,723 boxes marketed in 1938.
Cuts Cost 35 Percent
Getting more fruit from half as many trees cut the cost
of his orchards operations by 35 per cent. His fruit is of better quality
and color and there's plenty of moisture for all.
Now that his orchard problems were practically solved,
Card still spotted danger signs ahead. Bearing down from the highlands were
seasonal run-offs, washing tons of rich soil before it and carving gullies
in the orchard land. Card lost no time and setting up a second line of defense
to cope with his slipping soil.
In the pages of his farm conservation plan which S.C.S.
soil technicians worked out with him, Card found an effective way of combating
his soil losses. On tap were "erosion stoppers," ways of improving his soils,
and practices which would assure the permanence of his fruit crop.
Card ridged the steep bank back of the orchard with a
diversion terrace. Next he constructed a 2,500-foot wide grass waterway to
carry off the run-off water from the terrace. To prevent erosion of the waterway,
Card seeded it to alta fescue, blue grass, brome, and alsike clover. A barnyard
milch was added after the planting.
Terracing of 70 of his 115 acres of extra-steep grass
and crop lands was finished in the summer of 1946. The 1,300-foot long and
15-foot wide terraces are seeded to red creeping fescue as a sod builder
and erosion deterrent.
Evergreen For Windbreaks
Card is also growing a windbreak along the banks of the
terraces with plantings of two rows of Douglas firs and Port Orford cedars.
Cropland between the terraces is seeded to alfalfa and
alta fescue grass. The latter is harvested for seed and the alfalfa is chopped
up for orchard mulch.
Card has put plenty of hard work into his new cover-crop
system. The thick vegetative cover, spreading over his orchard, anchors his
soil, saves moisture, and feeds tree-roots needed organic vitamins. His
cover-cropping treatment vary with the needs of his orchard soils.
In the fall the orchard land is seeded to an annual
cover-crop of vetch and rye. Card disked it in May and follows up by covering
it with a blanket of straw and hay, spread from four to eight tons per acre,
depending on the slope of the land. Steeper pitched slopes require a heavier
and thicker mulch to stay run-off.
His cover-crops are fertilized with a heavy mixture of
phosphorus, nitrogen, and potash, applied at the rate of 200 pounds per acre
in the fall and followed with an application of 200 additional pounds in
the spring.
His cover-cropping measures used on the Card ranch are
now a common practice on orchards in the Underwood Soil Conservation District.
"You can't get results overnight from every farm practice
you put in," he said, "but if a farmer expects to stay in business permanently,
he should be willing to wait until the conservation measures he has installed
begin paying off, as they surely will."
