Chitosan in agriculture: what it is for and how to use chitosan for plant care. The use of the chitosan in organic farming as a fertilizer and as a stimulant for plant growth.
Chitosan, what is it
Thechitosanit is a natural substance that improves the resistance of plants against various harmful organisms. What is chitosan? We are talking about a polysaccharide (a sugar) extracted from chitin. Chitin is the substance that makes up the integuments that cover insects and crustaceans. Chitin is a compound also present in cell wall of some mushrooms.
Thechitosanthat we find on the market is obtained fromgrinding of crustacean shellssuch as lobster, shrimp and crab.
Chitosan in agriculture
Thechitosanis a productalternativeused inagriculturewithoutcontraindicationsfor plants. This substance can be used to improve plant health but must be used as asupplementand not as a miracle remedy.
In addition to supplementing plant growth with thechitosanit will be necessary to make sure that the purchased plants are suitable for the place of planting, both for exposure and for temperature, climate and soil quality. Theplantsthey should not be subjected to adaptation stress. Adaptation stress is the leading cause of susceptibility toplant diseases.
Thechitosanconstitutes an excellent natural remedy forstrengthen plant growth, it is a good onefertilizerwhich can increase resistance to bacteria, viruses, fungi and other diseases. Along with the administration ofchitosanas a supplement, to support its function, it will be necessary to provide for irrigation, pruning, cleaning of the flower beds… In short, no natural remedy alone can replace the good agronomic practices necessary for the development and growth of plants.
Chitosan, how it works and what it is used for
Thechitosan it is not a realfertilizerbut it is called an alternative remedy for its mechanism of action.
In agriculture, it is distributed on the leaves or by roots. It will need to be administered every 3 to 4 weeks. By doing so, the plant is induced to recognize this substance as a danger and will produce barrier structures. The plant will trigger defense mechanisms activated by chitosan but which will be useful for defending the plant organism from real pathogens capable of attacking the plant.
Thechitosantherefore, it has no direct action on pathogens (viruses, fungi, bacteria, various parasites ...) but it stimulates the plant to promptly activate forms of defense against the most varied infections.
Thechitosan in agricultureit is also used asstimulatingboth for plants and to facilitate seed gemination. Applied on the seeds, thechitosanstimulates the growth of healthy and strong shoots, which are able to protect themselves from the aggression of parasites early.
As stated, thechitosan in organic farmingor inhome garden, does not presentcontraindicationsnor safety times. Aqueous solutions in which the chitosan has been diluted can be sprayed on the plants even during the harvest period. It will not be necessary to wait for any "safety interval" because fruits and vegetables can be harvested even immediately after the distribution of this particular sugar.

The other uses of chitosan and its properties
Chitosan is used as a supplement not only for plants but also in human nutrition. In particular, chitosan is used as a supplement in low-calorie diets for reducing body weight.
