Unit 5: Predicting the Effects of Climate Change on Soil Loss part of A Growing Concern
Students will investigate how the factors that influence erosion work together to produce an overall erosion rate. In agricultural areas, these factors are rainfall-runoff erosivity, soil erodibility, slope ...

Unit 4: Using SoilWebTMto Investigate the Soil Beneath You part of A Growing Concern
Students will use SoilWeb™, a smartphone and web application that pulls detailed soil survey data from both the 1:24,0000 Soil Survey Geographic database (SSURGO) and the 1:250,000 scale State Soil Geographic ...

A Growing Concern: Sustaining Soil Resources through Local Decision Making part of A Growing Concern

Unit 1: Impacts of Land Use part of A Growing Concern
In this introductory unit, students will learn about the fundamental role of observation by viewing photographs of both agricultural and non-agricultural (natural) landscapes and making independent observations. ...

Unit 2: Soil Characteristics and Their Relationship to Land Use Practices part of A Growing Concern
In a hands-on exploration, students will learn to describe and quantify the porosity and permeability of soil models representative of both agricultural and natural environments. Students will use this information ...

Unit 6: Creating an Agricultural "Fact Sheet" part of A Growing Concern
For a given region, students will use what they have learned about the interdisciplinary problem of soil sustainability to make recommendations for agricultural practices in response to potential changes in ...
