- CWT is an abbreviation for hundredweight, a unit of measurement equivalent to 100 pounds in the US (the “short hundredweight”, or “cental”) and 112 pounds (a “long hundredweight”) in the UK. CWT is typically used to price agricultural or industrial goods (particularly raw materials) such as fruits and vegetables, grains, steel, and livestock.
Lettuce production in the United States is primarily concentrated in two states: California and Arizona. These states boast significant agricultural output, particularly conducive climates, and suitable soil conditions for lettuce cultivation. Lettuce requires cool temperatures, adequate sunlight, well-drained soil, and consistent moisture levels to thrive. California, with its diverse microclimates ranging from coastal regions to inland valleys, provides ideal growing conditions for lettuce throughout much of the year. Similarly, Arizona’s warm and arid climate, coupled with modern irrigation systems, supports lettuce cultivation, especially during the winter months when other regions experience colder temperatures.
California, often referred to as the nation’s salad bowl, leads lettuce production in the United States, accounting for a substantial portion of the country’s lettuce supply. Its vast agricultural expanses, particularly in the Central Valley and Salinas Valley, contribute to high lettuce yields year-round. Arizona, known for its fertile agricultural regions, such as the Yuma and Imperial Valleys, also plays a significant role in lettuce production, particularly during the winter season when it benefits from milder temperatures compared to other parts of the country. Together, California and Arizona’s contributions make them key players in meeting the nation’s demand for fresh lettuce.
