Explanation should include
- identifying the physical and chemical properties of soil, including organic matter, macronutrient, and micronutrient availability
- describing how soil quality directly affects water quality, biodiversity, wildlife habitat, plant growth, and crop production
- explaining how to improve soil quality
- analyzing a plot of land to determine which soil management techniques would be most applicable
- identifying the planned use of the soil
- evaluating soil management practices (e.g., no-till farming, cover crops, addition of organic matter)
- using regenerative agriculture practices such as multispecies cover crops and soil carbon monitoring
- devising a soil management plan to minimize erosion and maximize biodiversity, plant productivity, and the formation of topsoil.
