USDA soil taxonomy (ST) developed by the United States Department of Agriculture and the National Cooperative Soil Survey provides an elaborate classification of soil types according to several parameters (most commonly their properties) and in several levels: Order, Suborder, Great Group, Subgroup, Family, and Series.
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.
It is also used to describe a topsoil horizon that contains organic matter (humus type, [4] humus form, [5] or humus profile [6]). Humus has many nutrients that improve the health of soil, nitrogen being the most important. The ratio of carbon to nitrogen of humus commonly ranges between 8:1 and 15:1 with the median being about 12:1. [7]
The soil should be kept moist and shaded until the plants emerge. Young plants can be transplanted in a well prepared growing bed with a high organic matter in a planting distance of 6–10 inches (15–25 centimetres). To support the plants with nutrients, pine needles, rotted conifer-derived sawdust or bark mulch should be added to the top soil.
