Skills and knowledge to be acquired:

To be able to make environmentally and economically sound soil management decisions. To be able to predict soil behavior and field preformance.

Computer skills to be acquired:

None

Pre-requisites:

One of CHEM 151, CHEM 161, CHEM 171 or CHEM 181A; or consent.

Cross-Listed courses:

NREM 304

Text(s):

Field Trips:

A field trip to study the different soil types on Oahu.

Course organization:

The lectures will cover:

  • Origin of Soils  
  • Soil Chemistry and Testing
  • Soil Composition and Minerals
  • Soil Physical Properties
  • Nutrients: N, P, K, Ca, Mg, S, Micro-nutrients
  • Nutrient Management
  • Soil Water
  • Soil Temperature
  • Soil Air
  • Soil Organisms
  • Soil Microbial Processes
  • Plant-Soil Microorganisms Interactions
  • Soil Classification
  • Soil Information Systems and Sources

Laboratory includes:

  • Field Tour
  • Soil Acidity and Liming
  • Rocks and Minerals
  • Soil Density, Texture
  • Greenhouse Experiment
  • Nutrient Deficiency Symptoms
  • Water Potential and Content
  • Soil Microorganisms
  • Soil Survey Reports
  • Soil testing

Grading:

To help you focus on topics, you will be given homework assignments every Friday based on the following week’s reading and lecture topics. Homework will be due that following Friday.

There will be two midterms and a final exam. The midterm exams will cover material for which you have not been previously tested. The final examination will test your overall understanding of soil science.

There is one lab report collected for grading. This report is on the outcome of a greenhouse soil fertility experiment. The report should include (1) research objectives, (2) review of literature, (3) materials and methods, (4) results and discussion, and (5) conclusions.

1st Midterm Exam 20%
2nd Midterm Exam 20%
Final Exam 35%
Reading-based Homework 15%
Green House Lab Report 10%
