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...

Water and anion movement in selected soils of western Oregon

Creator:

Hammermeister, Dale P.

Abstract:

Experiments were carried out to study the movement of water and halide anions in perched water tables or saturated zones in the soil and upper rock mantle of eight different experimental sites located on low hills near the western border of the Willamette Valley. At each site the experimental procedure...
