- Understand that soil is composed of inorganic and organic solid material, water, and air.·Investigate the properties of the inorganic solid components of soil: sand, silt, and clay.
- Recognize that varying proportions of sand, silt, and clay in a soil impact the soil’s ability to hold and transmit water. Experimentally determine the soil texture of a local soil sample.
- Determine the chemical composition of a local soil sample for pH, nitrate, phosphorus, and potassium levels.
- Analyze a given soil’s ability to support crops such as corn, soybeans, wheat, and oats.
- Provide recommendations for amending a given soil to support the needs of various crop plants.
