SOILS
Soil is a mixture of mineral and organic material at the surface of the earth that serves as a natural medium for growing plants.
The five factors that control the formation of soils are:
-
Climate
-
Organisms
-
Topography
-
Parent Material
-
Time
The Soils section of the contest will be broken up into several categories, including soil properties, soil biology, landforms and parent material, soil maps, and interpretations. A soil profile will be excavated and available for students to describe horizons, texture, structure, permeability, depth to water table, color, and other features.
