Commitment & Innovation Define U.S. Cotton Production
U.S. cotton producers are leading the way in responsible cotton production practices.
Through the support of research and implementation of technology, U.S. cotton production is on the path to continual improvement, maximizing efficiencies while minimizing inputs.
Setting Science-Based Targets
Commitment and innovation define U.S. cotton production. Over the last 35 years, the commitment of U.S. cotton producers, researchers, and industry organizations led to dramatic reductions in land use, soil loss, water use, energy use, and greenhouse gas emissions.
Innovation in technologies, management systems, and conservation created opportunities for advancements in yield while taking stewardship of natural resources for cotton agriculture to the highest levels in the world.
For the next decade and beyond, U.S. cotton producers and industry organizations are setting new environmental targets to keep pushing the frontier of sustainability and leading the worldwide effort in responsible cotton production.
The target areas and goals were established using science-based evaluations, including key performance indicators (KPIs) for producing each pound of cotton and pathways to achieve them.
Increase Soil Carbon by 30%
Increasing soil carbon, often referred to as regenerative agriculture, is seen by many organizations as a key strategy to reducing atmospheric greenhouse gas (GHG) that leads to climate change. The soil carbon measurement is important not only for understanding carbon flows to and from cotton fields, but it is also an accepted indicator of soil health.
There is a significant growing interest in the use of winter cover crops by U.S. producers and there has been an increasing trend towards no-tillage and strip tillage.
In addition to reducing the amount of GHG released to the atmosphere, improving soil health can also contribute to increased crop yields, reduced water use, increased nutrient uptake, reduced fertilizer use, reduced nutrient runoff, and reduced soil loss.
No-till practices increase microbes and organic matter in the soil. In the image on the right, Dr. Bill Robertson, Extension Cotton Agronomist at the University of Arkansas Division of Agriculture, holds up two examples of this: The degraded cotton underwear (on the left) demonstrates the microbes present in healthy soils as well as the ability of cotton to biodegrade compared to synthetics (on the right) after a five-week time period.

Increase Land Use Efficiency by 13%
The effective use of agricultural land is critical to creating a more sustainable future.
Population growth and the related increased demand for food and fiber necessitates a need to maximize land use efficiency, or yield.
The U.S. cotton industry continues to increase its land-use efficiency by:
- Increasing cotton fiber yields through better genetic varieties and appropriate grower management.
- Reducing the amount of water per pound of cotton, especially with highly uniform water delivery systems.
- Improving soil health through crop rotation, no-till practices, and the planting of cover crops.
- Implementing improved irrigation scheduling tools (e.g., computer programs and sensors).
Research aimed at increasing cotton yields and reducing cotton land use are seen as key priorities for reaching these sustainability goals while also increasing the profitability of growers.
Geospatial technologies and digital technology applications provide growers with information to improve land-use efficiency.
Of the many areas of research and activities to increase yields, the following are some of the most promising:
- The use of geospatial technologies that analyze in-field water and nutrient measurements to expand precision applications.
- The incorporation of digital technology applications across cooperating growers to provide greater predictive power to grower decisions.
- Preserving the low insect-, weed-, and disease-related yield loss that U.S. growers currently experience.
- Expanding soil health knowledge and implementing practices that foster a diverse and healthy rhizosphere.
- Further adoption of in-field, plant-based sensors to optimize irrigation in variable-rate systems.
- Furthering the use of CRISPR genome editing, which has been demonstrated in cotton.1 The CRISPR technology is superior to traditional biotechnology approaches for its reduced regulatory burden, genome location precision, trait flexibility, and potential to broaden the providers of genetic innovations for agriculture.2
- Improvements in plant breeding techniques combined with more rapid adoption of improved varieties.
Setting Sustainability Goals
Cotton Incorporated’s Vice President of Agriculture and Environmental Research, Dr. Kater Hake, and Chief Sustainability Officer, Dr. Jesse Daystar, discuss the goal-setting process by the U.S. cotton industry as well as the path producers, researchers, and stakeholders are on to achieve these goals.
This webinar focuses on the sustainability goal to increase land-use efficiency and how this goal is heavily connected to the other five sustainability goals

Decrease Greenhouse Gas Emissions by 39%
Cotton growth naturally removes CO2 from the environment through photosynthesis. However, the use of fertilizers and other on-farm activities release CO2 and other greenhouse gas (GHG) to the environment.
One of the strongest contributors to cotton’s agricultural GHG footprint is the use of synthetic nitrogen (N) and its energy-intensive manufacturing process. In addition, N is a strong GHG contributor because a small percent of applied N fertilizer is lost to the atmosphere as nitrous oxide, a potent GHG.
The cotton industry is working with scientists to decrease the amount of nitrogen required to produce each pound of cotton through efforts to increase nitrogen use efficiency (NUE).
Refined management systems are calling for precise amounts of nitrogen to eliminate waste and over application.
With the increased use of site-specific management and new technologies such as on-the-go sensors, there will be increases in NUE and corresponding decreases in GHG emissions.
Sensors enable growers to more accurately measure plant needs and to be more efficient with the inputs applied to the crop.
Reducing Climate Impacts in Agriculture
USDA Research Agronomist, Dr. Arlene Adviento-Borbe, and Cotton Incorporated’s Chief Sustainability Officer, Dr. Jesse Daystar, discuss the latest cotton research focused on greenhouse gas emissions and conservation cropping systems at the Judd Hill Foundation Farm in Arkansas—a research project supported by Cotton Incorporated.

Decrease Soil Loss Per Acre by 50%
Soil conservation efforts are a high priority for cotton farmers as soil losses can create environmental degradation, reduce farm productivity, and decrease the quality and quantity of usable soil. While cotton field soils are continually produced from parent material, the industry goal is to produce more new soil than is lost due to water or wind erosion.
From 1980 to 2005, large numbers of cotton growers in the Mid-South and Southeast adopted conservation tillage to reduce soil erosion.
This land-use pattern was aided by the launch of cotton varieties tolerant to broad-spectrum foliar herbicides in 1997, and by their rapid adoption across the U.S. Cotton Belt over the next five years.3 More recently, grower interest in cover crops for weed suppression and for soil health has extended the protection of soil to intense rainfall. Cover crop adoption for weed control and soil health will continue to be an important component of continuous improvement efforts of the U.S. cotton industry.
Weed resistance will continue to expand as more weed species gain resistance to existing herbicide modes of action. Since no new modes of action4 are anticipated in the next ten years, growers will be under even greater pressure to adopt cover crops to suppress weeds. Research will clarify which cover crop species and varieties provide allelopathic weed suppression, enhancing cover crop efficacy.
Cover crops suppress weeds, improve soil health, and prevent soil loss.
Soil health is a major initiative of the USDA-NRCS.5 The initiative is designed to expand the benefits of rhizosphere biology (nutrient and water uptake through roots) by increasing the soil organic matter and diversity of shoots, roots, and microbes grown in the field. Ancillary benefits include seedling wind protection and pathogen suppression. Grower adoption of soil health measures will continue to be promoted in educational outreach efforts.
The majority of the U.S. cotton crop is grown without irrigation or with only supplemental irrigation. Thus, rainwater capture, infiltration, and protection from soil surface evaporation are beneficial for cotton yield. With increasing intensity of rainfall attributed to climate change,6 research and educational efforts will increase the use of no-till, cover crops, and surface residue which all enhance rainwater utilization. These practices also prevent soil erosion.
Decrease Water Use by 18%
Cotton is an inherently drought-tolerant crop, however, in some regions of the U.S., cotton fields are irrigated to increase productivity. Increasing water-use efficiency (WUE) would allow growers to produce more cotton using the same amount of water; doing more with less. This increase would help the U.S. cotton industry meet the demand for more sustainable fibers while using fewer resources per pound of cotton.
Over the past several decades, U.S. cotton growers have increased yields without increasing water use. This historical progress has been achieved through the use of tools and practices such as:
- The implementation of better water delivery systems (e.g. Pipe Planner®, laser leveling, low nozzle center pivots, and drip irrigation) to
- The use of improved irrigation scheduling tools (e.g., computer programs, and crop and soil sensors).
The trend of increased yields without increased water use will continue, as the adoption of irrigation scheduling technologies is promoted.
Better water delivery systems help growers to increase water use efficiency by delivering water closer to the plant, preventing evaporation. The irrigation system uses scheduling tools to only apply water when and where it is needed.
There is a strong business case for improving WUE. Data from Daystar et al. (2017)7 indicate that producers using sensor-based irrigation achieved 100 pounds higher yield/acre without increased water use compared to producers not using sensors.
Did you know U.S. cotton growers can use smartphone apps to schedule irrigation only when the cotton plant needs it? Learn how “Smart Irrigation” works from George Vellidis, professor of Agricultural Engineering at the University of Georgia.
Increasing Cotton’s Water Productivity
Increasing water-use efficiency (WUE) is a cotton industry goal to allow growers to produce more cotton using the same amount of water. Though cotton is an inherently drought-tolerant crop, efforts are still being made to further increase productivity by irrigating cotton fields in certain regions of the U.S.
In this webinar, Cotton Incorporated’s Dr. Ed Barnes and Dr. Jesse Daystar discuss the metrics and methods the cotton industry is using to chart progress towards its water productivity goal and the technologies being implemented by farmers in the field to help us get there.

Decrease Energy Use by 15%
The primary energy expenditures in cotton production include manufacturing nitrogen fertilizer, harvesting, ginning, and tillage. U.S. cotton growers began reducing their energy expenditures in the 1980s by employing reduced tillage and reducing nitrogen applications per pound of fiber produced. Since the energy requirements for harvesting and ginning are relatively constant, the pathway to further decreases will be addressed by the increase in the number of growers employing reduced tillage and reduced nitrogen applications, as well as emerging technologies.
Several promising technologies will be available in the 10 to 30-year time frame that will lower the harvesting and ginning energy consumption, including:
Robotic implements are already available for factory and residential cleaning. Considering the large market for robotic implements in agriculture, these will be entering the market soon and will lower cotton harvesting energy use and cost.
Gene Editing of Fiber to Seed Attachment Force
Even without a major improvement in machinery, it is anticipated that gene editing will facilitate the development of cotton varieties with lower gin energy costs due to the ability to manipulate the fiber to seed attachment force (ginning represents approximately 25% of the U.S. cotton energy footprint for non-irrigated conditions).
Robotic technologies are one tool that U.S. cotton growers can employ to further decrease their energy use in the near future.
Learn more about the tools and technologies that U.S. cotton ginners can employ to reduce energy during the ginning process from Paul Funk, USDA Agricultural Research Service-Southwestern Cotton Ginning Research Laboratory.
The Goal-Setting Process
The goal-setting process followed the Framework for Sustainable Agriculture standard S629 recently adopted by the American Society of Agricultural and Biological Engineers (ASABE). Leaders from U.S. cotton industry organizations including the National Cotton Council, Cotton Board, Cotton Council International, and Cotton Incorporated engaged ten technical experts in cotton biology and production to discuss how future technologies would impact trends in 14 key performance indicators, which are used to assess the sustainability of cotton production systems. In addition to leading experts in cotton production-related fields, a recent survey of over 50 cotton producers on their perceptions of future opportunities and challenges influenced the discussion.
As a result, recommendations for six science-based U.S. cotton industry goals were presented to the newly formed U.S. cotton sustainability task force. A seventh goal, enrolling 2.5 million acres in the Fieldprint® Calculator, was also set. The Fieldprint Calculator is the tool that will measure progress and each environmental KPI.
Framework for Sustainable Agriculture
by American Society of Agricultural & Biological Engineers, Standard S629
The recommendations included goals for the next five, ten, and 30 years. The five and ten-year goals are more tactical in nature, while the 30-year goals reflect aspirational goals for the industry. This summary document highlights the ten-year goals as approved by the U.S. cotton sustainability task force.
