The soil suborders within an order are differentiated on the basis of soil properties and horizons which depend on soil moisture and temperature. Forty-seven suborders are recognized in the United States. [6] The soil great group category is a subdivision of a suborder in which the kind and sequence of soil horizons distinguish one soil from ...
The National Cooperative Soil Survey Program (NCSS) is a partnership led by the United States Department of Agriculture's Natural Resources Conservation Service of Federal land management agencies, state agricultural experiment stations, counties, conservation districts, and other special-purpose districts that provide soil survey information necessary for understanding, managing, conserving ...
Soils are the product of climate, organisms and topography, acting on parent (geologic) material over time. Thus the great diversity of geologic materials, geomorphic processes, climatic conditions, biotic assemblages and land surface ages in the United States is responsible for the presence of an enormous variety of mineral and organic soils.
Ultisol, commonly known as red clay soil, is one of twelve soil orders in the United States Department of Agriculture soil taxonomy. The word "Ultisol" is derived from "ultimate", because Ultisols were seen as the ultimate product of continuous weathering of minerals in a humid, temperate climate without new soil formation via glaciation .
A state soil is a soil that has special significance to a particular state. Each state in the United States has selected a state soil, twenty of which have been legislatively established. These official state soils share the same level of distinction as official state flowers and birds .
The practice of water management focuses on the efficiently controlling the flow of water while causing the least amount of damage to life and property. [35] This helps to provide protection in high risk areas from flooding. Irrigation management is the most efficient way to use and recycle water resources for land owners and farmers. [35]
The Soil and Water Conservation Act (RCA) is a 1977 law (P.L. 95-192) that requires the United States Department of Agriculture (USDA) to periodically prepare a national plan for soil and water conservation on private lands based on an inventory and appraisal of existing resource conditions and trends.

The large woody root traces can transport water and clay using their large pipes. They are very efficient at moving soil into a subsurface horizon when the plant dies and the roots decay.
