Inheriting Chemical Foundations, Innovating Agricultural Solutions
Building on its foundation in chemical technology, Diamond Quantum applies nano calcium carbonate across industries, extending its use to agriculture by combining chemical and biotechnology to develop scientifically advanced and environmentally friendly products. Upholding the principles of innovation and practicality, we actively develop non-registered plant protection materials that are both safe and eco-friendly. These products effectively combat pests and diseases, are suitable for a variety of crops, and provide farmers with solutions that enhance efficiency while reducing the environmental impact of chemical pesticides.
In 2019, Diamond Quantum officially entered the agricultural biotechnology field, partnering with top Taiwanese academic and research institutions to focus on developing beneficial microorganisms. We have transferred and developed multiple technologies, including products from Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus siamensis, and Streptomyces species. We believe that healthy soil is the foundation of sustainable agriculture, and our organic and microbial fertilizers provide scientific and effective solutions for soil improvement, disease resistance enhancement, and yield increase.
Diamond Quantum practices its core value of “Land Friendly, Environmentally Caring” by promoting organic agriculture through the use of calcium carbonate fertilizers and liquid organic fertilizers.
