d
Definition: Small percentage of Earth's land that is suitable for cultivation, used for cropland, orchards, and livestock pasture.

Flashcard #6
Term: Factors Influencing Soil Productivity
Definition: Climate, latitude, and topography play a significant role in soil productivity.

Flashcard #7
Term: Ion-exchange capacity
Definition: The ability of soil to hold nutrients for plant uptake.

Flashcard #8
Term: pH levels in soil
Definition: Optimal around neutral for most crops; low pH decreases nutrient availability.

Flashcard #9
Term: Macronutrient requirements
Definition: Essential nutrients for plant growth include nitrogen, phosphorus, and potassium.

Flashcard #10
Term: Soil Horizons
Definition: Layers formed by natural processes in soil, impacting drainage and nutrient retention.

Flashcard #11
Term: Soil Filtration
Definition: Soil acts as a natural filter, crucial for maintaining clean water.

Flashcard #12
Term: Soil Texture
Definition: Determined by particle sizes: sand (largest), silt (medium), clay (smallest), influencing growth and water movement.

Flashcard #13
Term: Erosion and Soil Degradation
Definition: Caused by overexploitation and leads to nutrient depletion and soil loss.

Flashcard #14
Term: Surface Mining
Definition: Type of mining that creates dust, water contamination from tailings, and habitat destruction.

Flashcard #17
Term: Reserve
Definition: Known quantity of economically recoverable resources.

Flashcard #18
Term: Tailings
Definition: Waste material from mining processes.

Flashcard #19
Term: Weathering and Soil Formation
Definition: Physical and chemical processes create soils from parent materials.

Flashcard #20
