To the North West horticulturist there is no
problem which confronts him of so great moment as that
of soil fertility; and. no phase of horticulture is
more deserving of the attention of fruit growers, than
is given at the present time to the growing of orchard.
cover crops.
Annual cover crops are widely used in the Willamette Valley of Oregon on hill land, in orchards and on overflow river bottom land. Cover crops are grown to prevent soil erosion and to increase soil organic matter. The objectives of this study were to determine the crops that would be...

Three experiments whose objectives were to investigate cover
crop kill by winter freeze, weed suppression by 'Micah' barley and
other spring cereals, and allelopathic potential of cereal covers
were conducted at the Vegetable Research Farm and in the greenhouse
and growth chamber facilities at OSU in 1989/90. Kill by winter...
Cover crops planted in late summer are an inexpensive way to build better soil for gardening. Cover crops often are
called green manure crops. They are grains, grasses, or legumes that will grow during fall and winter and that you
can plow, spade, or till under in the spring.
The contamination of ground water resources represents a serious
problem and a prominent threat to the health of our society. This study
focuses on the leaching of inorganic anions as a function of agricultural
practices under natural field conditions. In order to enhance the
understanding of such leaching processes, this...
The experiment was conducted to compare multiple pest (weed, soil arthropod and diseases) suppression by cereal cover crops in 'Selva' and 'Totem' strawberry. In addition, perlite was used to compare improvement of soil and root aeration which might modify strawberry black root rot complex. Small-seeded summer annual weeds were suppressed...
