The primary purpose of this study was to determine if inservicing Agriculture Science and Technology (AST) teachers over a new curriculum, resulted in increased student achievement. Specific objectives were to: 1) determine the subject areas (lessons) for a curriculum for teaching Integrated Pest Management (IPM); 2) develop a curriculum for...
This publication recommends management practices for controlling diseases and insects. This pest management guide was prepared for the home gardener. It doesn’t meet the exacting requirements of the commercial fruit grower. Many fungicides and insecticides are available, which, when used according to the label directions, are effective in managing diseases...

Nutrient management plans for crops require estimates of plant-available nitrogen (PAN) provided by application of manure or compost. Recent developments have stimulated interest in utilizing manure nitrogen (N) as a resource. These factors include the following:
• Increased cost of N fertilizers
• Increased value of PAN from manure on...
The purpose of the study was to determine if the delivery of an integrated
agriculture and science curriculum to the Agricultural Education MAT (Master of Arts
in Teaching) students, increased their desire and ability to integrate their curriculum and

The Willamette Valley of Oregon has high rates of winter precipitation that cause leaching losses of residual fertilizer nitrogen (N) as nitrate (NO₃). Cover crops may have potential to mitigate N loss. Shallow groundwater was sampled for 11 years from plots planted in summer vegetables with and without winter cover...
According to the United States Geological Survey, 9 percent of wells in the Willamette Valley exceed the EPA’s 10 ppm drinking water standard for nitrogen in the NO3– compound, or NO3–-N. A study of 281 domestic drinking water wells in Lane County showed that 22 percent of the wells exceeded...
