Seaweed Polysaccharides + 8 Chelated Elements: A "Marine-Grade" Comprehensive Nutrition Solution for Crops

This product is an ultra-concentrated full-nutrition liquid fertilizer with a high density of 1:1.4, revolutionarily integrating five major and medium elements: nitrogen, phosphorus, potassium, calcium, and magnesium. It is also rich in seaweed extract and eight chelated trace elements (B, Fe, Mn, Zn, Cu, Mo, Ti, Se). It aims to provide all-around support for crops from foundational nutrition to biostimulation:

1. Comprehensive Nutritional Coverage: Macro, secondary, and micro-elements in one step. Provides N>10%, P>4%, K>4% basic nutrition, while containing high calcium (CaO>12%) and high magnesium (MgO>4%), effectively strengthening plant cell walls, promoting chlorophyll synthesis, and preventing calcium-deficiency blossom-end rot and magnesium-deficiency yellowing.

2. Seaweed Polysaccharide Stress Resistance: Activates plant immunity. >2% seaweed oligosaccharides (the core component of seaweed extract) act as natural biostimulants, significantly enhancing crop resistance to drought, salinity, and diseases, activating beneficial microorganisms in the rhizosphere, and improving nutrient absorption efficiency.

3. 8-Dimensional Trace Element Guarantee: Comprehensively repairs physiological deficiencies. A total content of >3% of chelated trace elements such as boron, iron, manganese, zinc, copper, molybdenum, titanium, and cesium ensures high bioavailability, avoids soil antagonism, and supports enzyme activity, photosynthesis, and reproductive growth.

4. Synergistic Efficacy: Builds a healthy soil-plant ecosystem. The synergistic action of macro, secondary, and micro-elements with seaweed polysaccharides optimizes soil fertility structure, comprehensively enhancing crop vitality, yield, and quality.

5. High-Density Liquid Advantage: Precise, efficient, and easy to apply. The ultra-high density of 1:1.4 ensures nutrient concentration. It is a 100% water-soluble liquid, suitable for various irrigation systems without clogging nozzles, ensuring nutrients evenly and directly reach target parts of the crop.

Expert Advice: As a general-purpose, full-nutrition product, it is suitable for the entire growth period of crops (especially vegetative growth and early fruit setting). It is recommended to be applied via flushing, drip irrigation, or foliar spraying as a powerful supplement to conventional fertilization programs.

1

What are the synergistic advantages of the 13 elements in this product, and what is the core role of seaweed oligosaccharides?

The core advantage of this product lies in its full nutritional combination and seaweed active empowerment: Nitrogen ensures the nitrogen source needed for crop growth, promoting strong leaves and shoots; phosphorus and potassium synergize to promote flower bud differentiation and strong, lodging-resistant plants; calcium and magnesium strengthen cell walls and prevent deficiency-induced yellowing. Seven trace elements, including boron, iron, and manganese, accurately fill the trace element gap, avoiding problems like malformed fruits and little leaf disease. As a biostimulant, seaweed oligosaccharides can activate crop root activity, improve the absorption efficiency of each element, and simultaneously enhance the crop's resistance to cold, drought, and disease, achieving a three-in-one effect of "nourishment + absorption promotion + stress resistance".
