During the past 50 years, plantation Christmas tree production has grown in acreage and sophistication. Nitrogen applications with a tuna can have been replaced by precise, mechanized application of a wide array of nutrients and lime.
Current nutrient management programs must focus on three concepts for success.

Poor quality water or an inadequate supply of water can take the pleasure from country living. Problems with quantity or quality of domestic water occur all over Oregon.
Most dairies need no commercial fertilizer if they use manure properly. In most cases, manure can supply all the nitrogen, phosphorus, potassium, and several other nutrients needed for forage production.
Cranberry plants require proper amounts of certain chemical elements from air, water, and soil to ensure adequate vegetative growth and fruit production. When levels of these nutrients in the plant are low, growth and yield may be affected.
Perennial ryegrass (Lolium perenne L.), also called English ryegrass, is a cool-season perennial bunchgrass native to Europe, temperate Asia, and North Africa. It is widely distributed throughout the world, including North and South America, Europe, New Zealand, and Australia.
Tall fescue (Festuca arundinacea Schreb.) is a perennial, cool-season bunchgrass that is grown for pasture, hay, and silage. Native to Europe and North Africa, it was introduced from Europe to North and South America.
Soft white winter wheat grown in western Oregon requires a spring application of nitrogen (N) fertilizer for optimum production. Determining the amount of N to apply has been a challenge for growers because wheat is produced in numerous rotations that provide varying amounts of N to the wheat crop. Inadequate...
Laboratory soil tests will help you develop
and maintain more productive soil and
increase crop production by providing
information on the available nutrient content of
your soil. Soil testing helps you select the
correct kind and amount of fertilizer and liming
material. Recommendations are based on the
results of fertilizer...
Many nutrients and lime are not mobile in the soil. When applied to the soil surface without tillage, these materials remain in the top 2 inches, especially in production systems that lack tillage. If a soil sample is taken at a standard 8-inch depth, the top 1 to 2 inches,...
