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

Agriculture in the state of Alaska is unique and diverse. The state’s climate and geography allow for a wide variety of crops and livestock to be raised.

Agriculture is an important part of the state’s economy, providing jobs for many Alaskans.

Now, it’s time to take a look at the US Plant Hardiness Zone Map of the state.

Plant Hardiness Zone Map For Alaska


Alaskan mean annual temperatures range from the low 40s in the south to 10° F along the arctic slope north of the Brooks Mountain Range.

In winter, the minimum temperature drops down to -20˚ to -30˚F.


The annual average rainfall amounts to over 200 inches in the southeastern part to around 150 inches along the northern coast of the Gulf of Alaska.

Amounts decrease to near 60 inches on the southern side of the Alaska Range in the Alaskan Peninsula and the Aleutian Islands sections.

Soil Order Of Alaska

Soil TypeLocationCharacterstics
EntisolsOn flood plains and outwash plains, on uplands adjacent to major rivers, in other young material such as recently exposed glacial moraines and very cold or very steep areas.1. Wet mineral soils.
2. Have no diagnostic horizons other than an ochric epipedon
HistosolsSouthern Alaska1. Made up of organic material.
InceptisolsFound everywhere except southeastern Alaska, the south-central Alaska mountains, and the Cook Inlet-Susitna1. Have an umbric and mollic epipedon with a cambic horizon
2. Poorly drained soils with permanent frost
MollisolsMostly in Tundra areas but a few occur on calcareous or nonacid material in forested regions1. Have a mollic epipedon with no underlying horizon dominated by ashy material.
2. Base saturation more than 50%.
3. Have a wide range in drainage conditions and texture.
SpodosolsCommon in forested areas of southeastern Alaska, south-central Alaska mountains, Cook Inlet-Susitna Lowland, and Kuskokwim Highlands1. Have a surface mat of organic matter
2. The amounts of organic carbon, aluminum, and iron are accumulated in the spodic horizon
