Chitosan Plant Fertilizer is a concentrated liquid nutrition product developed for fruit trees, especially mature or weakened trees with rough, aging or damaged bark. With chitosan oligosaccharide as the central functional ingredient, the formula also supplies NPK, organic acids, amino acids, humic substances and other readily available nutrients. It can be used on trunks, around the root zone or on foliage as part of a broader orchard maintenance program.
Product Introduction
Shandong Zhongnong Fuyuan Ecological Agriculture Development Co., Ltd. is one of the leading manufacturers and suppliers of chitosan plant fertilizer in China, also supports high quality customized service. If you're going to wholesale bulk advanced chitosan plant fertilizer made in China, welcome to get quotation from our factory.
As fruit trees age, the condition of the trunk and bark can gradually deteriorate. Rough bark, peeling outer tissues and weakened branches are often accompanied by lower tree vigor and reduced nutrient movement. Simply increasing soil fertilizer does not always address these visible problems.
This formulation takes a different approach. Chitosan Plant Fertilizer can provide nutrition directly to treated woody tissues while also supplying functional components associated with plant recovery and stress response.
The product contains ≥5% chitosan oligosaccharide, together with organic acids, fructonic acid, amino acids, humic acid and NPK ≥8%. The combination is intended to support bark condition, root activity, foliage growth and overall tree vitality rather than functioning as a single-purpose NPK fertilizer.
EFFICIENT BARK REPAIR STRONG TREE PROTECTION
Main Benefits
One of the main uses of the product is on older fruit trees with rough, aging or damaged outer bark.
The formulation provides nutrition to the bark surface and supports normal tissue renewal. As old, damaged outer tissues gradually loosen, the trunk can develop a cleaner and healthier appearance without relying solely on manual bark scraping.
Woody tissues can serve as an additional route for supplying nutrients to perennial crops.
The liquid formula is readily absorbed and provides NPK together with amino acids, humic substances and organic components, helping maintain active growth in roots, leaves and branches.
Weak trees often show several problems at the same time: poor rooting, thin branches, declining foliage and lower resistance to environmental stress.
By providing both nutritional and biostimulant components, the product supports overall tree vigor and helps maintain a stronger physiological condition throughout the growing cycle.
Although trunk care is a key feature, the formula is not limited to bark nutrition.
It can also be incorporated into root-zone and foliar management programs, allowing one formulation to support root development, healthy leaves, branch growth and tree recovery.
Chitosan oligosaccharide is widely used in plant biostimulant programs because of its role in plant physiological and defense responses.
For fruit trees exposed to early-spring cold, drought or other unfavorable conditions, maintaining stronger tree nutrition can contribute to better resilience and recovery.
Healthy branches and active foliage provide the foundation for flowering, fruit setting and fruit development.
The nutritional components in the formula support fruit enlargement, surface appearance and overall quality as part of a complete orchard nutrition program.
HIGHLY ABSORBABLE NUTRITIONAL FORMULA
Designed for Mature and Aging Fruit Trees
Older orchards often require different management from newly established plantations. The challenge is no longer only to stimulate growth, but to maintain productive wood, active bark tissues, strong roots and sufficient nutrient circulation year after year.
This is where Chitosan Plant Fertilizer fits particularly well. Its chitosan-rich formulation is intended to work with the tree itself, providing supplemental nutrition while supporting renewal of aging tissues.
For trees with rough or peeling bark, the goal is not simply cosmetic. Healthier trunk tissues, stronger roots and active foliage are closely connected to the long-term productivity of the orchard.
The product can therefore be positioned as an orchard maintenance input for mature trees, weakened trees and perennial crops requiring more intensive trunk and nutritional care.
