Half ＆ Mu Fang 98% + Chitosan Oligosaccharides (Agricultural Grade), COS, Fully Water-Soluble Plant, Horticultural and Fruit and Vegetable Fertilizer(250g/8.8oz)

Half ＆ Mu Fang Agricultural-Grade chitosan oligosaccharides are refined from high-quality crustaceans such as shrimp and crab shells. They efficiently retain the biological activity of chitosan oligosaccharides, possess biocompatibility and degradability, are full water solubility, and are widely used in agricultural production.Content :>98%Appearance: Yellow powderDeacetylation (DAC degree): ≥85％；pH：5-7Fine inorganic arsenic :≤0.5ppmLead :≤0.ppmWater-insoluble matter :≤0.5%Moisture content :≤10%Ash content :≤2‌Key Benefits of Agricultural-Grade Chitosan Oligosaccharide:Promoting root growth, with a well-developed root system, a significant increase in the number of root hairs and secondary roots, and a well-developed root zone, will enhance the plant's ability to absorb nutrients and water, as well as its drought resistance and lodging resistance. Improve the soil, increase the organic matter content of the soil and enhance the fertilizer efficiency.Usage & Dosage:This product is a fully soluble powder and can be directly sprayed without filtration.1.For foliar spray or root irrigation: First dissolve in 10x water as stock solution, then dilute 300-400x before application. Apply 1-2 times per crop season (recommended at seedling stage and full bloom), with annual maximum of 2-3 applications.2.Apply with water: Use 28-48 grams per hectare and apply evenly with water Foliar sprayConcentration: 30-50ppm (0.03-0.05g per kg of water)Dosage: 2.1-3.5g powder per hectare per application, diluted and sprayed. Apply every 7-10 days for 2-3 consecutive applications.Soil flushing/drip irrigation Soil improvement: Mix with organic fertilizer, 140-560 grams per hectareStorage:Store in a cool, dry, and dark place at room temperature. After opening the bag, if not used up, seal it well and store in a cool and dry place.
