Technology to produce chitosan films in combination with chelating complexes, metal nanoparticles coated with urea and some other fertilizers

The project proposed a process to create oligochitosan solution with a high content of 10% without drying in order to reduce production costs; creating a coating mixture combining oligochitosan with trace amino acid chelators to coat urea and NPK fertilizers, creating a new line of fertilizers.

Experiments have been conducted on potted broccoli and hot peppers in coco peat substrates (the soil is less fertile) and on a narrow trial of these fertilizers on kohlrabi, corn, rice, oranges and dragon fruit in different soils in Lam Dong, Tien Giang, Ca Mau, Long An and Can Tho. The results show that, for red-fleshed dragon fruit, the project's fertilizer product gives better plant growth, better fruit quality, higher yield, good for long-term stable development of the plant, compared to most other fertilizers tested by Ca Mau Petroleum Fertilizer Joint Stock Company. For hot pepper plants grown in pots on coco peat substrate, the yield can increase up to 300% compared to conventional fertilizers.

The joint test showed that the fertilizer products of the project had a positive impact on the growth, development, increased yield, fruit quality, and reduced the amount of fertilizer used on tested fruit trees, bringing economic value as well as helping to reduce environmental pollution due to excess fertilizer use.The joint test showed that the fertilizer products of the project had a positive impact on the growth, development, increased yield, fruit quality, and reduced the amount of fertilizer used on tested fruit trees, bringing economic value as well as helping to reduce environmental pollution due to excess fertilizer use.
