Arkansas: Plant Hardiness Zones, Climate & Soil Conditions

Our experienced writers spend hours deep researching, considering both scientific and experimental info to bring the insights you can trust.  

Arkansas is a leading producer of rice, soybeans, cotton, poultry, and aquaculture. The state’s topography is diverse, with the Ozark Mountains in the northwest corner and the Arkansas Delta in the southeast.

This diversity allows for a wide variety of crops to be grown. Arkansas’s climate is also conducive to agriculture.

The state has hot summers and mild winters. This means that crops can be grown year-round.

There are also plenty of rivers and streams, which provide irrigation for fields.

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

Soil Order Of Arkansas

Soil / Sub OrderLocationCharacteristics
Entisols/FluventsIn the Boston and Ouachita Mountains1. Fluvents are the more or less freely drained Entisols that formed in recent water-deposited sediments.
Vertisols/AquertsIn the Mississippi alluvial plains and some parts of Arkansas Valleys1. Aquerts are the wet Vertisols. Drainage of cropland presents special problems since the saturated hydraulic conductivity of these soils is very low.
Ultisols/UdultsMostly all over the state.1. Udults are the more or less freely drained, relatively humus-poor Ultisols that have a udic moisture regime.
Alfisols/Aqualfs and UdalfsIn the eastern and southern parts of the state.1. Aqualfs have warm and aquic conditions.
2. Udalfs have a udic moisture regime.
Inceptisols/AqueptsIn the Mississippi alluvial plains.1.Aquepts are wet Inceptisols that require artificial drainage due to their poor natural drainage.
