peck reach vary in their dirt types . Many ranges or case-by-case pot are rocky and have only small amounts of filth , but many also have plentiful amount of dirt . The United States Department of Agriculture carve up soils into 12 fiat , each with discrete feature article . Seven of these occur oftentimes in mint . To translate how best to grow plants in craggy areas , it is important to be able to place what form of soil you have and what its various strengths and weaknesses are .

Ultisols

Soils in the ultisol order hap in the main in the Southeast and contain large measure of clay . This kind of soil is rough-cut in the Appalachian mount range but can also be find in the Cascades of Washington and Oregon . It is often found in more humid mood . Ultisols are usually acidic and check most nutrients in the upper few inch of the ground . They do not retain fertilizer well .

Inceptisols

Inceptisols are some of the most rough-cut soils in craggy regions . They can be found in the Appalachians , the Cascades , the Sierra Nevadas and the Rocky Mountains , although they are not as coarse there . The soils in this order are widely varied and occur in climates ranging from humid to semi - desiccate . This type of soil is not highly weather and does not contain silicate clay .

Spodosols

Soils of this edict are not found in many mountain ranges but do have a bearing in the Cascades and the higher - altitude areas of the Rocky Mountains . Spodosols are often find under coniferous forest and are highly acidic and nutrient - poor . They are also humiliated in constituent matter .

Andisols

Andisols are rich dirt and hold nutrients and H2O very well . They often check volcanic materials and can often be found in area with greater - than - average amounts of rain . As such , it is unsurprising that they take place primarily in the Cascades . They are also present in the Rocky Mountains in northern Idaho .

Entisols

Entisols are present in the Rocky Mountains and the southerly Sierra Nevadas . They form in areas with high corrosion , peculiarly usurious slopes and dunes . They are often composed of material like sand , metal oxides and corpse .

Alfisols

Alfisols are scatter throughout various hilly areas , especially the Appalachians and the Rocky Mountains . They are less vulgar in the Cascades and the Sierra Nevadas . They often form under timber and take cadaver in the subsoil ( rather than close to the control surface ) . They are often very in effect grunge for USDA .
