After googling...
Organic cotton is generally understood as
cotton, from non
genetically modified plants, that is certified to be grown without the use of any synthetic agricultural chemicals such as
fertilizers or
pesticides.
[1] Its production also promotes and enhances biodiversity and biological cycles.
[2]In the United States cotton plantations must also meet the requirementsenforced by the National Organic Program (NOP), from the USDA, in orderto be considered organic. This institution determines the allowedpractices for pest control, growing, fertilizing, and handling oforganic crops.
[3][4]As of 2007, 265,517 bales of organic cotton were produced in 24countries and worldwide production was growing at a rate of more than50% per year.

Advantages
Cotton growers who make the transition to biologically based growingpractices expect to not only offer a healthier and cleaner product, butto also benefit the planet. Some of the contributions to the differentecosystems include:
- Protecting surface and groundwater quality (eliminating contaminants in surface runoff)保护地表水和地下水的质量（消除地表径流污染物）
- Reduced risk insect and disease control by replacing insecticide with the manipulation of ecosystems降低风险，减少昆虫和疾病，取代杀虫剂
- Long-term prevention of pests through beneficial habitat planting. 有利长期防止害虫
- Conservation of biodiversity保护生物多样性
- Eliminate the use of toxic chemicals used in cotton
消除棉花使用的有毒化学品 - Organically grown crops also yield soils with higher organic mattercontent, thicker topsoil depth, higher polysaccharide content, andlower modulus of rupture; therefore reducing considerably soil erosion
大概意思~

"传统的棉花生产普遍使用杀虫剂，全球２５％的杀虫剂用来抑制棉花病虫害。而有机棉花则不使用任何杀虫剂，生产过程中也不用任何漂白剂或染料，从而不会导致过敏症的出现。"
