Now, let us see the soil orders of the state.

Soil Order Of Delaware

Soil / Sub OrderLocationCharacteristics
Histosols/HemistsIn the middle Atlantic coastal plain across the eastern boundary.1. Hemists are the wet Histosols in which the organic materials are moderately decomposed.
Entisols/Aquents, Arents and PsammentsIn the middle Atlantic coastal plain.1. Aquents are the wet Entisols.
2. Arents do not have diagnostic horizons because they have been deeply mixed by plowing, spading, or other methods of moving by humans.
Psamments are sandy soils.
Ultisols/Aquults and UdultsAquults in the southern part of the state while Udults mostly across the state except for the southern part.1.
Psamments are sandy soils.
2.Udults are the more or less freely drained, relatively humus-poor Ultisols that have a udic moisture regime.
