Creator:: Heinrich, Aaron and Sullivan, Dan M.
Abstract:: Following the surface application of urea to soil, there is the potential for nitrogen (N) loss from ammonia (NH3) volatilization until sufficient rain or irrigation has moved it into the soil. Many studies measuring NH3 loss have used laboratory and microplot field studies. The limitation of these techniques is that...

Creator:: Khemira, Habib
Abstract:: The effect of canopy orientation on fruiting performance of 'Beurre d'Anjou' pears (Pyrus communis L.) and postharvest urea spray on ovule longevity and fruit set of 'Doyenne du Comice' pears were studied. Hedgerows of 'Beurre d'Anjou' pear trees planted in 1969 in two orientations north-south (N-S) and east-west (E-W) were...

Creator:: Marion, Carol I.
Abstract:: Three rates of urea, urea-DCD, and NH₄N0₃ were soil applied in April and August 1986 to strawberry selection OR-US 4930 and cultivar 'Sumas' to determine effects of the nitrification inhibitor dicyandiamide (DCD) and nitrogen source and rate on soil NH₄ and N0₃ levels, fruit yield and quality, and mineral composition...

Creator:: White, Linda D. (Linda Dee)
Abstract:: The effect of incorporated sawdust, sawdust mulch and nitrogen (N) fertilizer rate on soil nutrients and other properties, N uptake, and plant growth in a young blueberry planting on a silt loam soil type was studied in 2004 and 2005. ‘Elliott’ highbush blueberry plants were established on raised beds that...
