Cover crops and biochemical functional diversity in relation to nitrogen availability in soil

Creator:

Burket, John Zimmerman

Abstract:

Nitrogen availability in agricultural soils from fertilizer, plant residue inputs, and soil organic matter has important implications beyond crop yield. Legume winter cover crops and one fourth the recommended N rate on sweet corn resulted in yields equivalent to those at the recommended rate in the Willamette Valley of western...

Soil quality dynamics in an integrated reduced-tillage and cover-cropped vegetable agroecosystem

Creator:

Banners, Candace R.

Abstract:

Soil response and function were investigated following the adoption of an integrated reduced-tillage and cover-cropped vegetable system in the Willamette Valley of Western Oregon. The experiment was conducted over three cropping seasons (2002-2004) at the Oregon State University Vegetable Research Farm (Corvallis, OR). The design was a randomized complete-block with...
