Soil Science 101 with Dr. Jay Goos

Dr. Jay Goos joins us from the department of soil science at North Dakota State University to share his approach to introducing soil science to his students and his experiences over the last four decades in the field. The overall curriculum of his course focuses on teaching the “main properties of soil” including acidity and alkalinity, concepts of wilting point, field capacity and “how the layers of the soil influences productivity.” He hopes that his students leave with an understanding of the soil health big picture.

But beyond introducing and sharing the value of soil science with future generations and assisting agriculture with iron deficiencies in soybeans, Dr. Goos has also been a part of soil science for forty years. He has seen many trends, practices and concerns come and go and overall is happy to see all of the progress that has been made in regards to soil health. He does want to call attention to phosphorus availability in the future due to limited sources and the chronic “mining (of) our soils for nutrients” without replacing the overall gross deficit.

“Everyone is thinking about nitrogen now because of the dead zone in the Gulf of Mexico and nitrates in rivers and streams. But Phosphorus is going to be moving up on the people’s radar over the next few decades.” - Dr. Jay Goos

He comments that unfortunately something that has not changed in the last 40 years is that “farmers are still bombarded with snake oil products.” Dr. Goos encourages students and farmers to understand soil variability and learn about the many factors that influence overall soil health. He recommends reaching beyond “gizmos” when learning about precision agriculture and focus more on what causes field variation and how we can best manage it.
