This system for classifying soils has undergone numerous changes since that time, and the 2nd edition was published in 1999. Soil Taxonomy remains one of the most widely used soil classification systems in the world. At the highest level, Soil Taxonomy places soils in one of 12 categories known as orders. We have put together a collection of information and images to illustrate the distribution, properties, ecological significance, and use of these 12 soil orders.

Introduction to Soils Introduction An important factor influencing the productivity of our planet's various ecosystems is the nature of their soils . Soils are vital for the existence of many forms of life that have evolved on our planet. For example, soils provide vascular plants with a medium for growth and supply these organisms with most of their nutritional requirements. Further, the nutrient status of ecosystem's soils not only limit both plant growth, but also the productivity of consumer type organisms further down the food chain Soil itself is very complex. It would be very wrong to think of soils as just a collection of fine mineral particles. Soil also contains air, water, dead organic matter, and various types of living organisms (

Soil, is made from rocks that break apart or wear away over many years. This is referred to as weathering. It may take 100 to 1,000 years for 1 cm of soil to form through weathering. Soil also contains air, water, and humus, the decayed remains of dead animals and plants. Soil can actually be separated into 5 main parts. They are: Humus: A dark, moist soil composed of bits of dead, rotting insects, animals, leaves, roots, sticks, and food. Humus adds nutrients to the soil which plants need to grow and live. Clay: A soil that holds water. When wet, clay feels slippery and slimy. It is made of particles that are smaller than 0.004 millimeters. Silt: Soil that looks like fine grains or tiny pieces of rock. Particles classified as silt measure from 0.004 millimeters to 0.006 millimeters. Sand: Soil that is coarse and drains quickly. Sand particles measure from about 0.006 millimeters to 2.00 millimeters.

Crops Home MSUcares Home Soils Soil is the unifying factor in Mississippi crop production. Understanding the fundamental properties of soils proceeds to better appreciation of soil fertility and fertilization, as well as soil management and conservation. Integrating nutrient management, soil management, and conservation leads to considering soil quality or health. Simply put, soil quality is the ability of a particular soil to function as desired. Some functions include crop production, water control, or structure support. What exactly is soil? There are many, many definitions. Specific ones depend on the viewpoint of the user. Some stakeholders consider soil to the living, breathing substance near the earth's surface which fosters life on all scales. Others consider it to be the aggravating skim on the earth's surface. The study of soil is not the study of dirt. Dirt does not have life sustaining properties. Greenhouse media is not soil either. It does not have the unique three-dimensional characteristics that can only evolve as a function of place, time, and the environment. More information on soil properties and formation are available on the Master Gardener reference manual links below.

COVERING THE LITHOSPHERE Although soil has many uses, it is really just a layer of dirt between the atmosphere and the bedrock in the tectonic plates . The top layer of the planet is called the lithosphere . Soil is the loose stuff on the surface of the lithosphere. We have talked about plate tectonics and swirling clouds in the atmosphere. In the same way those conditions change, the soil changes. It changes very slowly but very definitely. It's a very complex system that supports all of the life on land. MORE THAN DIRT Soil is much more than just dirt. It is the result of the breakdown of rocks. The breakdown is both physical and chemical. Soil is mainly something scientists call regolith . Regolith is sandwiched between the bedrock (the rock that makes up the continents) and the actual loose soil (the top stuff at the surface). If you see a tree you know its roots make it into the soil. They could even go all the way to the regolith and stop when they get to the bedrock. FROM HERE TO THERE As the process of erosion happens, some areas are built up and some areas are destroyed. The first thing to change is the soil. One extreme example would be the Grand Canyon. Over millions of years, the Colorado River has eroded and washed away tons of soil and rocks at the surface. It all went to the ocean eventually. Inland processes work the same way. The soil and rocks from the sides of a mountain move downhill and collect in the lower areas. Slowly the valleys fill up with very rich soil and minerals. Soil is always moving.

Individual cells abut each other to form the filaments. Click on image for full size. Cryptobiotic soil crusts, consisting of soil cyanobacteria, lichens and mosses, play an important ecological roles in the arid Southwest. In the cold deserts of the Colorado Plateau region (parts of Utah, Arizona Colorado, and New Mexico), these crusts are extraordinarily well-developed, often representing over 70 percent of the living ground cover. Cryptobiotic crusts increase the stability of otherwise easily eroded soils, increase water infiltration in regions that receive little precipitation, and increase fertility in soils often limited in essential nutrients such as nitrogen and carbon (Harper and Marble, 1988; Johansen, 1993; Metting, 1991; Belnap and Gardner, 1993; Belnap, 1994; Williams et al., 1995).
