Soil scientists record the characteristics of the pedons, associated plant communities, geology, landforms, and other features that they study. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil and to determine their boundaries. Soil scientists can observe only a limited number of pedons. Some boundaries are sharp, where soils change over a few meters, while others are more gradual. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. Hierarchical systems of classes and subclasses are established to produce groupings at the different scales.Ĭommonly, individual soils on the landscape merge into one another as their characteristics gradually change. A system of terminology, definitions, and operations can be ascribed to the various scales. These patterns are the basis for soil identification and mapping at different scales. The repetitive patterns imprinted in soils by the soil-forming factors can be observed at scales ranging from continental to microscopic. Thus, during mapping, these models enable the soil scientist to predict with considerable accuracy the kind of soil or miscellaneous area on the landscape (Hudson, 1992). By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they formed. Soil scientists delineate these repeating patterns of landform segments, or natural bodies, on a map. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. The soils and miscellaneous areas (e.g., Rock outcrop) in a survey area are in an orderly pattern that is related to the geology, landforms, topography, climate, and natural vegetation. Soil mapping is the process of delineating natural bodies of soils, classifying and grouping the delineated soils into map units, and capturing soil property information for interpreting and depicting soil spatial distribution on a map.

In this procedure, the fibroids are frozen. The procedure Acessa is an example of myolysis. This procedure shrinks the fibroid by blocking its blood flow with a heat source, such as a laser or an electric current. This procedure attempts to destroy the fibroid with sound waves. This procedure blocks the blood flow to the fibroid with a goal of shrinking or terminating it. A myomectomy is a surgical procedure that removes one or multiple fibroids. This is a surgery that removes the entire uterus. This treatment is designed to reduce the size of the fibroid. There are a number of therapies, like GnRH agonists, designed to lower the levels of estrogen. Treatment options for all fibroids include: Your doctor will recommend treatment if you are experiencing pain or if you’re worried about getting pregnant or your current pregnancy.
Pedunculated fibroids are, for the most part, not treated.
