Alabama: 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.  

Alabama’s agriculture is as diverse as the state’s landscape.

From the fertile Black Belt soils that give birth to cotton and peanuts to the rolling hills and valleys that are home to cattle and chicken farms, Alabama farmers produce a variety of crops and livestock.

The state’s climate also lends itself to a wide range of agricultural production.

Warm temperatures and long growing seasons allow for the year-round production of many fruits and vegetables, while cooler temperatures in the northern part of the state are ideal for growing winter wheat.

Soil Regions of Alabama

Now, we will understand the soil order of the state in these regions with the help of a table.

Soil Order Of Alabama

Soil / Sub OrderLocationCharacteristics
Ultisols / UdultsFound all over the state.1. Udults are the more or less freely drained, relatively humus-poor Ultisols that have a udic moisture regime.
Inceptisols / Aquepts and UdeptsAquepts in the major floodplains and terraces and Udepts in parts of the coastal plain.1. Aquepts are wet Inceptisol
2. Udepts are mainly freely drained Inceptisols that have a udic or perudic moisture regime.
Entisols / Aquents and FluventsAquents in the coastal plains and Fluvents in a small part of limestone valleys and uplands.1. Aquents are the wet Entisols.
2. Fluvents are the more or less freely drained Entisols that formed in recent water-deposited sediments.
Vertisols / UdertsIn the coastal plains.1. Uderts are the Vertisols of humid areas. They have cracks that open and close, depending on the amount of precipitation.
Alfisols / UdalfsIn some parts of the Appalachian plateau1. Udalfs have a udic moisture regime.
