The lack of organic matter in Ultisol makes it difficult for plants to grow without proper care and considerations.
Soil amendments are generally required each year in order to sustain plant life in regions with primarily Ultisol soil.
The use of soil tests, coupled with the corresponding provisions, can alleviate issues of nutrition and irrigation that can result from non porous Ultisol.
Soil tests help indicate the pH, and red clay soil typically has a low pH. The addition of lime is used to help to increase the pH in soil and can help increase the pH in Ultisol as well.

Clay soil is known to retain nutrients very well because its negative charge helps to attract cations.
As a result, Ultisol does not often require the high amounts of fertilizer additions other types of soils often do.
However, this retention of nutrients coincides with a lack of water filtration that may subject plants to highly saturated soil.
Not all plants can survive in the moist, humid Ultisol found throughout the Southeastern United States and elsewhere.
