Agronomic Soil Testing in Oregon

This course covers basic agronomic soil testing topics for agriculture professionals working in the state of Oregon. The course is meant for crop advisors, agronomists, soil laboratory managers and staff, farm managers, and consultants who are responsible for making decisions about soil testing.

You will learn about selecting a soil testing lab and OSU recommended soil tests. The lectures will help you learn about:

  • Soil pH testing, including buffer pH and calcium carbonate testing.
  • Soil nitrogen testing, including nitrate and ammonium, nitrogen mineralization, and total nitrogen testing.
  • Soil phosphorus, potassium, sulfate, magnesium, and calcium testing.
  • Cation exchange capacity and base saturation testing.
  • Soil zinc, manganese, copper, iron, and boron testing.
  • Electrical conductivity, soluble cations, and sodium adsorption ratio testing.
  • Soil organic matter and carbon testing.
  • Cornell soil health testing.
  • Other soil health testing.

What You'll Learn

After completing this course, you should be able to to:

  • Take a representative soil sample and select an appropriate soil testing lab.
  • Demonstrate a basic understanding of soil agronomic soil analyses methods recommended by OSU.
  • Understand the efficacy of nitrogen mineralization and soil health testing methods offered by soil testing labs.

Amber Moore

Amber Moore conducts applied research and develops nutrient and lime recommendations that improve nutrient use efficiency by large acreage crops grown in Oregon. The crops of primary focus are on grass grown for seed, cereals, and potatoes, with a secondary focus on minor crops (other seed crops, peppermint, forages, vegetables, berries, Christmas trees, etc.). Her research program is focused on developing soil fertility research efforts that are statistically sound and address current soil fertility needs in Oregon large acreage field crops. Research interests include fertilizer response, nitrogen mineralization, acidificaiton caused by nitrogen fertilizers, lime response, plant nutrient uptake, and soil nutrient dynamics.
