The purpose of this resource is to measure the amounts of nitrogen, phosphorous and potassium in each horizon in a soil profile. Using a NPK test kit, students mix a dry, sieved soil sample into a solution and chemically extract the N, P, and K as nitrate, phosphate, and potassium. The N, P, and K amounts in the sample are determined by comparing the solution to a color chart. Students describe the ... Full description.

The purpose of this resource is to measure the pH of a soil horizon. Students mix dried and sieved soil samples with distilled water. The mixture is allowed to settle until a relatively clear layer is formed. Students use a pH pen, pH meter, or pH paper to determine the pH of the sample. The procedure is done three times for each horizon. Full description.

This site offers an extensive collection of links to sites about water, life, and agriculture in the American West. Some of the articles are from the 19th century, when the arid, western United States was settled. Other pieces are more current and show how indigenous peoples of North America have survived in hostile terrains. Full description.
