Cover crop establishment in late-season crops, like sweet corn, may be difficult due to the relatively short operational window following crop harvest. In regions like western Oregon, where fall-precipitation can occur when the crop is still in the field, cover crops may not be able to be planted, due to...
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...
Although legumes have been widely studied for their nitrogen-fixing ability, it is uncertain to what extent legume cover crops achieve their nitrogen-fixing potential under the climatic conditions encountered in western Oregon. Furthermore, it is unknown what factors control the proportions of legume cover crop N that are either sequestered into...
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.
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...
Strip tillage is a form of conservation tillage that involves tilling
narrow strips for crop establishment while leaving areas between the strips with undisturbed crop residue. Strip tillage can reduce soil erosion and soil compaction, as well as machinery, fuel, and labor costs. Combined with winter cover crops, strip tillage...
