'Bio-cotton?'

BioCotton is the brand name of a new semi-manufactured finished product derived from organic cotton, which is obtained using bio-dynamic cultivation techniques. This form of cultivation substitutes chemical fertilizers and pesticides with certified natural fertilizers and with a programmed rotation of the cotton fields . Bio-dynamic cultivation takes into account the lunar phases best adapted for sowing. This is preceded by the introduction of homeopathic substances into the earth (such as mineral silicon) which reinforces soil structure. From this type of cultivation comes a high quality and easily worked product. The pure biological nature of the cotton makes this fiber both non-allergic and usable without warning indications even for people who are hypersensitive or affected with special skin pathologies (it doesn't alter neutral Ph), by breastfeeding or future mothers, by hospitals.
