*Note: This is an abbreviated Project Idea, without notes to start your background research, a specific list of materials, or a procedure for how to do the experiment. You can identify abbreviated Project Ideas by the asterisk at the end of the title. If you want a Project Idea with full instructions, please pick one without an asterisk.
Abstract
What variables contribute to the properties of the soil in an area? Investigate the role of climate, weather, topography, time, parent material, vegetation, and biological and chemical agents on soil formation. How are soils characterized? There are 3 basic particle sizes which create three basic soil types: sand, silt, and clay. Investigate the properties of the three different types of soil by observing grain size, shape, hardness, color, chemical composition, pore space, aeration, moisture content and permeability. How can soil management affect soil quality? Characterize the different horizons in the soil in a deep pit or by using the auger method.

Ask an Expert
The Ask an Expert Forum is intended to be a place where students can go to find answers to science questions that they have been unable to find using other resources. If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot.Ask an Expert

Soil Scientist
Not all dirt is created equal. In fact, different types of soil can make a big difference in some very important areas of our society. A building constructed on sandy soil might collapse during an earthquake, and crops planted in soil that doesn't drain properly might become waterlogged and rot after a rainstorm. It is the job of a soil scientist to evaluate soil conditions and help farmers, builders, and environmentalists decide how best to take advantage of local soils. Read more
Soil and Water Conservationist
Soil and water are two of Earth's most important natural resources. Earth would not be able to sustain life without nutritive soil to grow food and clean water to drink. Soil and water conservationists foster the science and art of natural resource conservation. The scientists work to discover, develop, implement, and constantly improve ways to use land that sustains its productive capacity, and enhances the environment at the same time. Soil and water conservationists are involved in improving conservation policy by bringing science and professional judgment to bear in shaping local, state, and federal policy. Read more
