Unit 2: Soil & Plant Nutrition

• LP 2.1: Analyze and interpret soil samples to calculate the percent composition of sand, silt, and clay.
• LP 2.2: Use a soil textural triangle to determine the soil type of a sample.
• LP 2.3: Determine traits of soil based on composition/type and propose remediation.
• LP 2.4: Identify essential plant nutrients (N, P, K) and their purposes.
• LP 2.5: Explain the role of bacteria in the nitrogen cycle and how nitrogen cycles through the environment.

• DCI: ESS2.A Earth Materials; LS2.B Cycles of Matter; LS2.C Ecosystem Dynamics: Understanding soil as a medium for nutrient cycling and system stability.
• SEP: Using Mathematics; Engaging in Argument from Evidence; Constructing Explanations: Used for soil classification and restoration planning.
• CCC: Structure and Function; Stability and Change; Energy and Matter: Identifying how physical structure impacts biological health.

• 4.a. Demonstrate Patterns - Graphical: Interpret sedimentation data and use the textural triangle grid.

• 3.a. Design Model - Predict Phenomena: Model water movement based on particle size and porosity/permeability.

• 5.c. Use Evidence/Theory - Reasoning: Diagnose nutrient deficiencies and develop restoration plans for depleted fields..
