How is Cotton Harvested?
Cotton harvesting is a significant process in the cotton industry, where machines have transformed the way cotton is harvested. In the United States, hand labor is no longer used, and two main types of machines are employed: cotton pickers and cotton strippers.
Cotton pickers are machines designed to twist the seed cotton from the bolls, ultimately leaving the plant intact in the field. These machines effectively remove the seed cotton from the bolls while leaving the burrs (dried locules) behind. The leftover burrs may later be addressed during the ginning process.
On the other hand, cotton strippers employ rollers or brushes to take the entire boll from the cotton plant, along with its leaves and branches. These machines collect the bolls using rollers equipped with bats and brushes, effectively separating the “seed cotton” from the boll and other debris. The seed cotton is then directed into a basket by the cotton stripper.
Regardless of the method employed, after cotton is harvested, it is formed into a module and then transported to the processing plant. Cotton harvesting typically begins in July in southern Texas and later in October in more northern regions of the country.
Understanding the Cotton Harvesting Process:
To better comprehend the intricacies of cotton harvesting, let’s delve into each process more deeply.
