How to Harvest Cotton: From Field to Fabrics
How to Harvest Cotton?
To harvest cotton, farmers use either cotton pickers or cotton strippers.
Cotton pickers remove seed cotton from the bolls while leaving the burrs behind.
They use spindles to pull the cotton out of the burrs and into a pneumatic conveying system.
On the other hand, cotton strippers are used to harvest storm-proof cotton by removing the complete boll from the plant.
Strippers use counter-rotating rolls with nylon brushes and rubber bats to strip the boll.
After harvesting, the seed cotton is packed into modules using a moveable tramper, which are then lifted and moved to another location.
Most cotton pickers today are highly automated, and round modules covered with polyethylene film are becoming more popular for protection and compression.
The harvested cotton, known as seed cotton, is then taken to a cotton gin to separate the fibers from the seed and remove any trash or leftover seeds.
The fibers are cleaned and packaged for use in textile manufacturing, while the cottonseed can be sold as feed or used for oil or planting the next year’s crop.

Did You Know?
1. Did you know that cotton plants belong to the same family as hibiscus and okra? These seemingly different plants all fall under the Malvaceae family.
2. Before the advent of modern machinery, cotton was harvested by hand, a labor-intensive process. It took approximately 600 hours of work to hand-pick enough cotton to produce one bale, weighing around 500 pounds!
3. The fibers of the cotton plant are not solely used for making textiles. Believe it or not, cotton is also found in some forms of currency, such as banknotes in more than 100 countries worldwide.
4. The cotton industry has a long history of innovation. In 1793, Eli Whitney invented the cotton gin, a machine that revolutionized cotton production by significantly speeding up the process of separating cotton fibers from their seeds.
5. Cotton is highly absorbent and can retain up to 27 times its own weight in water. This amazing property makes cotton an ideal choice for towels and bathrobes, as it effectively wicks moisture away from the body, providing comfort and quick drying.
Importance Of Timing In Cotton Harvesting
Harvesting cotton is not a simple task. It requires careful planning and precise timing in order to ensure optimal fiber quality and yield. Farmers often spend months planting and tending to their cotton crops, and the harvest marks the culmination of their hard work. However, harvesting too soon or waiting too long can have detrimental effects on the quality and quantity of the cotton fibers.
Timing is crucial because the cotton fibers undergo changes as the bolls mature. Harvesting too early can result in underdeveloped fibers that lack quality and strength. On the other hand, if the cotton is left on the plants for too long, the fibers can become overripe, leading to lower yield and compromised quality.
Farmers must closely monitor the cotton plants and the bolls to determine the optimal harvest time. They often take into account factors such as weather conditions, temperature, and the plant’s overall health. It requires experience and knowledge to gauge the right moment for harvesting.
The Role Of Cotton Pickers In Harvesting
Cotton pickers play a crucial role in the harvesting process of cotton. Their primary function is to separate seed cotton from the bolls while leaving the burrs behind. Seed cotton refers to the cotton fibers that are still attached to the seeds. Cotton pickers utilize spindles, which are rotating bars with wires or teeth, to gently extract the cotton from the burrs.
To efficiently transport the picked cotton, pickers are equipped with a pneumatic conveying system. This technology ensures that the cotton is effectively and quickly harvested while minimizing damage to the fibers.
In recent years, cotton pickers have witnessed significant automation. They are now often fitted with advanced sensors and technology that optimize the harvesting process. These machines can adjust their speed and function based on the condition of the cotton plants, resulting in maximum efficiency and minimal waste.
Harvesting Storm-Proof Cotton With Strippers
In areas prone to storms and inclement weather, farmers often opt for storm-proof cotton that can withstand harsh conditions. Harvesting storm-proof cotton requires a different approach compared to using cotton pickers. This is where cotton strippers come into play.
Cotton strippers are machines designed specifically for harvesting storm-proof cotton. They remove the complete boll from the plant, allowing for better protection of the valuable fibers. These machines use counter-rotating rolls with nylon brushes and rubber bats to gently remove the boll from the plant without damaging the fibers.
However, harvesting cotton with strippers has its trade-offs. The process tends to result in a higher trash content, as the strippers do not differentiate between the boll and other plant debris. This means that additional steps need to be taken to dispose of the plant trash effectively.

Disposing Of Plant Trash In Cotton Harvesting
Cotton harvesting, particularly with the use of strippers, results in a significant amount of plant trash, encompassing remaining bolls, stems, leaves, and other debris separate from the cotton fibers. Proper disposal of this plant trash is crucial to ensure an efficient and clean harvesting process.
Farmers have devised various methods for managing the plant trash. Some employ specialized equipment, such as shredders or balers, to gather and compact the plant debris. This compacted trash can be repurposed for activities like composting or serving as a source of biomass energy.
An alternative approach to disposing of plant trash involves plowing it back into the field. By integrating the plant debris into the soil, farmers can enhance soil fertility and increase its organic matter content. This practice sustains the overall health and productivity of the land for future cotton crops.
- Proper disposal of plant trash is imperative for efficient cotton harvesting.
Packing Seed Cotton Into Modules
Once the cotton is harvested, the next step is to pack the seed cotton into modules. Module builders are machines specially designed for this purpose. They compress and pack the seed cotton into large rectangular modules, typically measuring eight to twelve bales in size.
A moveable tramper is used within the module builder to compact the seed cotton densely. This compression helps protect the fibers and ensure that the modules are stable and transportable. Once the module is complete, it is lifted by hydraulics and pulled away to another location for storage or transportation to the gin.
In recent years, round modules have become increasingly popular. These modules are covered with an engineered polyethylene film, which provides protection and compression to the cotton. Round modules offer advantages such as improved weather resistance, reduced storage space requirements, and efficient transportation.

The Role Of Cotton Gins In Separating Cotton From Seed
After the cotton is harvested and packed into modules, it is transported to cotton gins for further processing. The purpose of a cotton gin is to separate the cotton fibers from the seed and remove any trash or leftover seed. Gins play a vital role in preparing the cotton for commercial use.
At the gin, the seed cotton goes through a series of cleaning and drying processes. Machinery removes foreign particles, such as dirt, sticks, and lint, from the cotton. The seed cotton is then fed into the gin’s saws, which separate the fibers from the seeds. The seeds and fibers are further processed and separated through various mechanisms, including air blowers and mechanical brushes.
Once the cotton fibers are separated, they undergo additional cleaning and packaging processes to ensure high-quality commercial products. The clean and packaged fibers are then ready for commerce, where they will be used for textile manufacturing. Additionally, the cottonseed that is separated during the ginning process can be sold as feed or used for oil production, or even saved for the next year’s crop.
harvesting cotton is a complex and multi-step process that requires careful timing, modern machinery, and attention to detail. From the use of cotton pickers and strippers to the proper disposal of plant trash, each stage plays a crucial role in ensuring the successful harvest of high-quality cotton. The cotton fibers and seeds are then separated at gins, and the fibers are cleaned, packaged, and prepared for textile manufacturing. The entire process, from field to fabrics, is a testament to the hard work and ingenuity of cotton farmers and industry professionals.
