Improving nitrogen management with cover crops in organic broccoli production

Creator:: Garrett, Amy
Abstract:: Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers. Predicting plant available...

Integration of conservation tilage and cover crops in broccoli production systems of the Pacific Northwest

Creator:: O'Brien, Timothy John
Abstract:: Field and greenhouse experiments were conducted in 1996 and 1997 to evaluate the effects of integrating conservation tillage and cover cropping on broccoli production as well as agroecological parameters. A field experiment was conducted during 1996-97 at the Oregon State University Horticulture Research farm near Corvallis, OR. The specific objectives...

Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

Creator:: Costello, Ryan C.
Abstract:: Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...

Weeds With a Purpose: Interseeding Cover Crops into Sweet Corn in Western Oregon

Creator:: Donaldson, Andrew R.
Abstract:: 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...
