Ultimately the goal is to separate the lint from the seed. First, any trash—such as grass or leaves—is removed from the bottom of the module. Next, fine-toothed saws pull out sticks and burs. The last step involves a crusher, which extracts the oil. Any leftover meal from the crushing process becomes feed for animals. The cotton lint now must be cleaned since it comes from the field and can contain field dirt, plant parts, mold, and bacteria.
Also, fibers must be removed from the seeds. Once it undergoes the cleaning process it enters a condenser, which converts the lint into pound bales of cotton. These bales are then shipped to textile mills or manufacturers, the last stop before cotton becomes a product used by consumers.
From textile mills comes apparel, ranging from t-shirts to socks to dresses, all made with natural cotton. Other manufacturers make a variety of consumer goods, such as wipes, diapers, or filters. Moths produced in the refuge crops will disperse and mate with any potentially resistant moths from the Bollgard 3 crops.
This tactic is called genetic dilution. Squares flower buds develop several weeks after the plant starts to grow, before flowers appear a few weeks later. The flowers then drop, leaving a ripening seed pod that produces fruit, known as bolls, after pollination. On irrigated cotton farms, the initial irrigation watering is usually followed by several additional irrigations at two-to-three week intervals depending on soil type and weather conditions from mid-December to late-February.
This differs depending on the region, average seasonal temperatures and soil type. The UN's Food and Agriculture Organisation defines IPM as "the careful consideration of all available pest control techniques and subsequent integration of appropriate measures that discourage the development of pest populations and keep pesticides and other interventions to levels that are economically justified and reduce or minimize risks to human health and the environment.
Growers conserve beneficial insects natural enemies to pests , and manage their natural resources to help suppress pests, which is at the heart of IPM. The use of biotechnology in cotton has made a significant contribution to the dramatic reduction in insecticides applied to Australian cotton crops. Growers usually choose to harvest the cotton crop once most bolls have opened and fully matured.
It is extremely important that cotton is dry when it is picked, or discolouration may occur and reduce quality. When mature, the crop is harvested mechanically and placed into large modules. The modules are loaded onto trucks and transported from the farm to a cotton gin. Cotton gins are factories that separate cottonseed and trash from the lint raw cotton fibre.
After ginning, the cotton lint is tightly pressed into bales. An Australian cotton bale weighs kilograms. Once the cotton bales are ginned, pressed and containerised, they are loaded onto trucks and trains and sent to ports for shipping, mostly to overseas markets. How Cotton is Grown. After cotton has been harvested, producers who use conventional tillage practices cut down and chop the cotton stalks.
The next step is to turn the remaining residue underneath the soil surface. Producers who practice a style of farming called conservation tillage often choose to leave their stalks standing and leave the plant residue on the surface of the soil. In the spring, farmers prepare for planting in several ways. Producers who plant using no-till or conservation tillage methods, use special equipment designed to plant the seed through the litter that covers the soil surface.
Producers in south Texas plant cotton as early as February. In Missouri and other northern parts of the Cotton Belt, they plant as late as June. Seeding is done with mechanical planters which cover as many as 10 to 24 rows at a time.
