Cotton prices are determined by cotton grades, so it’s important to understand what makes up a good grade and how you can optimize your management practices for high marks in the field.
Key factors that establish cotton grades for optimal cotton prices
Cotton grades, which determine cotton prices, are based on six important factors.
Color grade
The color grade of cotton depends on the environmental conditions to which your crop has been exposed. Cotton’s color is at its peak the day the boll opens. Factors that can negatively affect color grade include wet conditions or an early freeze.
Fiber length, strength and uniformity
These fiber characteristics are shaped by genetics and crop stress. Cotton of uniform fiber length tends to be aided by harvesting with a picker rather than by using stripper harvesting. The more mature the fiber, the more uniform the crop tends to be.1 This is why cotton harvest timing is important.
Micronaire
Micronaire is a measurement that indicates the fineness and maturity of fiber. It can be affected by your environment, the cotton variety you’ve selected and crop nutrition.
Leaf and trash content
The presence of leaves and trash at cotton harvest is determined by your defoliation strategy, which cotton variety you’ve used and your harvesting practices. Ideally, you’ll implement management practices that allow as many leaves as possible to drop from the plant pre-harvest, creating a cleaner final product. Although it’s fairly common to defoliate when roughly 60% of bolls are open, this won’t work in all cases.2
Moisture management post-harvest
The price of cotton depends in part on keeping your harvested crop dry to preserve fiber quality and maintain good cotton grades.
Genetic factors
Certain cotton varieties have proven production benefits including high fiber quality and strong yield potential. Broadening your genetic base can encourage crop resilience. You can learn more about available cotton seed and products such as FiberMax cotton, Stoneville cotton and Axant™ Flex herbicide tolerance technology on the BASF cotton webpage.
Crop management practices to promote high cotton grades
There are several crop management practices that can help you aim for top cotton prices.
Select top-performing genetics for strong cotton prices
You can boost both yield and quality by paying attention to DNA markers, breeding advances and modern variety evaluation. Scientists increasingly are focused on sequence-based screening, which allows researchers to pinpoint which plants to breed for optimal cotton productivity.3
Customize variety selection
Choose cotton varieties that are best for your local climate and that can stand up to disease pressures present in your fields.
Balance nutrient management for optimal price of cotton
Provide your cotton crop with balanced fertility spanning nitrogen, potassium, sulfur and boron. Nitrogen rates should be based on yield goals and soil tests using split applications on sandy for example. It is crucial to have adequate N availability during the early bloom stage.4 Monitor soil pH so conditions are optimal for nutrient uptake in cotton plants.
Implement a disease, insect pest and weed control strategy
Use integrated pest management to minimize damage from insects, diseases and weeds, and to improve grades of cotton. Select the right herbicides for your fields such as Liberty® ULTRA Herbicide or Outlook® Herbicide and apply them at the right time. Consider how cover cropping might help reduce fiber contamination and support good crop health.
Adjust timing of your defoliation and harvest for best results
Correct defoliation reduces trash and leaf content on cotton plants. It also improves picker efficiency and enhances the post-harvest drying process. A timely harvest minimizes weathering and preserves fiber color and strength.
Explore cropping and sustainability practices
Several additional management practices can support good cotton prices underpinned by high grades of cotton. These include planting cover crops, implementing strip-till systems and maintaining soil health to encourage good fiber quality and sustainability.
