answers students questions about soil
|
| What is soil? | Soil is an amalgamation of sand, silt, and clay particles,
combined with water, air, and many different microorganisms. (PDF

|
| Why is soil important? | Healthy productive soil is the foundation of a stable,
productive economy and the many environmental amenities all Americans
enjoy(PDF file)
|
| Soil Nutrients | Nutrients, mainly nitrogen, phosphorous, and potassium,
are applied to promote plant growth.
|
| Soil Test - Experiment | We all know that water moves down through the soil. This
is how rain or water from sprinklers can water our crops, veggie garden,
forests, or even our front lawn. But did you know that water moves through
different soils at different speeds?

| Control
of Soil Erosion
|
Canada Fact Sheet |
| Rill Erosion | Rill erosion often occurs with sheet erosion and is commonly
seen in paddocks of recently cultivated soils following high-intensity rainfall.
It is easily identified as a series of little channels or rills up to 30
cm deep.
|
| Splash Erosion | Soil movement by rainfall (raindrop splash) is usually
greatest and most noticeable during short-duration, high-intensity thunderstorms.
|
| Sheet Erosion | Sheet erosion involves the removal of a uniform thin
layer of soil by raindrop splash or water run-off. This thin layer of topsoil
often disappears gradually, making it difficult to monitor because the damage
is not immediately perceptible.

| Different
Styles of Farming and Their Environmental Impact
|
Traditionally, farmers have practiced a system of repeated
plowing, discing and cultivating to raise their crops.
|
| Farming and the Environment | Explore a variety of farming methods and learn how things
like manure and chemicals effect the earth.

| Crop Rotation as a Form of Conservation | "Any university person will tell you that the best way
to control weeds and insects and disease is with a good crop rotation."
|
| Backyard Conservation | Just as they do on the farm, conservation practices on
nonagricultural land can help increase food and shelter
for birds and other wildlife, control soil erosion, reduce sediment in waterways,
conserve water and improve water quality
|
| Benefits of Mulch | Mulching can be one of the most beneficial things you
can do for your soil and your plants. If you have not considered mulching
your garden in the past, you may want to reconsider.

| Importance
of Water
|
Our Earth seems to be unique among the other known celestial
bodies. It has water, which covers three-fourths of its surface and constitutes
60-70 wt % of the living world. Water regenerates and is redistributed through
evaporation, making it seem endlessly renewable. So why worry?
|
| POLLUTION
|
|
| Nonpoint Source Kids Pages | People are taking care of their home and car, but they
may be doing many things that can damage the environment, especially our
water. Look at the kids page on non-point pollution
|
| What is the nation's worst water quality problem? | Nonpoint source pollution is the largest source of water
quality problems. It is the main reason that 40% of our assessed water bodies
are unsafe for basic uses such as fishing or swimming.
|
| Forms of Surface Water Pollution | Water pollution is "contamination of water by undesirable
foreign matter." It impacts our oceans, our surface water, and our underground
water. Pollution comes in many forms--some conventional and others toxic.

|
| WATERSHED
|
|
| What is a Watershed? | It's the area of land that catches rain and snow and
drains or seeps into a marsh, stream, river, lake or groundwater.

| Why is EPA focusing on watersheds? | Water resource professionals are turning to watershed
management as a means for achieving greater results from their programs.
Why? Because managing water resource programs on a watershed basis makes
good sense -- environmentally, financially, and socially.

| SOIL SURVEY
|
|
| The Soil Survey: Its Use | A soil survey includes soil maps and descriptions of
each type of soil in the county, as well as interpretations of the soil's
characteristics and potential for community planning, agricultural land
management, engineering and wildlife management. (PDF file)

| WATER CYCLE
|
|
| Water Cycle | Water can exist either as a solid (ice), a liquid (water),
or a gas (water vapor). Water on the on surface of Earth is constantly changing
between these three states.
|
| Picture of Water Cycle | Water on earth moves in a continuous cycle. This is called
THE WATER CYCLE. There is about the same amount of water on earth now that
there was when the dinosaurs roamed our planet.
|
| WATER TREATMENT
|
|
| Water Treatment Path | Follow a drop of water from the source through the treatment
process. Water may be treated differently in different communities depending
on the quality of the water which enters the plant.
