Application of chitosan oligosaccharide in fertilizer field

In modern agriculture, fertilizers are crucial for enhancing crop yields and quality. However, the use of traditional chemical fertilizers is not only costly but also poses risks of environmental pollution and soil degradation. As a result, scientists have been actively exploring new eco-friendly fertilizers, among which chito-oligosaccharides (COS) have gradually garnered significant attention as an emerging biological fertilizer. This article aims to introduce the mechanism and effectiveness of COS in fertilizer applications in a user-friendly manner.

Chito-oligosaccharides (COS), also known as chitooligosaccharides or low-molecular-weight chitosan oligomers, are obtained through the degradation of chitosan using specialized bioenzymatic technology. Characterized by excellent water solubility, potent functional effects, and high biological activity, COS are the only naturally occurring cationic alkaline amino oligosaccharides with positive charges. These unique properties endow COS with broad application prospects in the agricultural field.

Numerous studies have demonstrated the remarkable effectiveness of COS fertilizers in agricultural applications. For instance, the application of COS fertilizers to grain crops such as wheat, rice, and corn significantly enhances crop yields and quality. When used on fruit trees and vegetables, COS fertilizers strengthen the plants' disease resistance and stress tolerance, while improving the taste and nutritional value of the fruits.

As a novel biological fertilizer, COS plays a significant role in promoting plant growth, enhancing plant stress tolerance, improving soil conditions, and increasing fertilizer use efficiency. With the continuous advancement of science and technology and the growing demand of agricultural production, the application prospects of COS fertilizers will become even broader.
