Palouse

Geography and History:
– The Palouse region is located in the northwestern United States, spanning parts of Idaho, Washington, and Oregon.
– Known for wheat and legume production, the area experienced rapid growth in the late 19th century.
– Home to the University of Idaho in Moscow and Washington State University in Pullman.
– Traditional Palouse region is defined as fertile hills north of the Snake River.
– Settlement boom in the 1880s due to successful wheat farming.
– Spokane served as a major urban hub and transportation center for the Palouse region.

Farming:
– Early farming in Palouse was labor-intensive, relying on human and horse-power.
– Combine harvesting became feasible in the 1930s with the invention of smaller machines.
– Transition to combine harvesters for wheat harvesting by 1930.
– Palouse region is now the most important lentil-growing region in the USA.
– Tractor use was limited initially due to steep hills, but increased with the introduction of smaller tractors in the 1920s.

Geology:
– Palouse Prairie characterized by loess hills underlain by wind-blown sediments.
– Palouse Loess covers over 50,000 sq mi in Washington, Idaho, and Oregon.
– Multiple layers of Palouse Loess separated by calcrete paleosols.
– Layers of loess accumulated between 2 and 1 million years ago.
– Uppermost layer of Palouse Loess accumulated between 15,000 years ago and modern times.

Agriculture Innovation:
– Idaho Harvester Company in Moscow played a crucial role in making combine harvesting feasible.
– Development of smaller tractors in the 1920s improved mechanization in Palouse.
– By 1930, 90% of Palouse wheat was harvested using combines.
– Palouse region now boasts advanced agricultural practices and technology.
– Tractor use increased as smaller, general-use tractors were introduced.

Ecological Impact:
– By 1910, 22,000 people lived in 30 communities on the Palouse Prairie.
– Agriculture intensification led to altered water quantity and quality, increased erosion, and loss of perennial prairie streams.
– Crop production surged post-World War II with the introduction of fertilizers.
– Significant conversion of grasslands and wetlands to agriculture.
– Grazing in canyonlands led to irreversible changes, replacing native grasses with annual grasses and noxious weeds.
