Advantages of seaweed extract fertilizer
1. Improve the nutrient absorption capacity of plants
Seaweed extract fertilizer contains rich active ingredients that can promote the growth of plant roots, thereby improving the plant's ability to absorb nutrients from the soil.
For example, the growth regulator components in certain seaweed can stimulate the development of capillary roots in the root system,
significantly improving the efficiency of plant nutrient acquisition.
2. Improve soil structure
The natural colloids and polysaccharides in seaweed extracts can improve the physical properties of soil, making it looser and more breathable,
increasing water holding and drainage capacity, and increasing the organic matter content of soil.
This improvement helps promote the reproduction of soil microorganisms and enhance the ecosystem function of the soil.
3. Improve plant stress resistance
The natural hormones, amino acids, and trace elements contained in seaweed extract fertilizers can enhance plant stress resistance and
resist adverse environmental factors such as drought, cold, and pests and diseases. For example, seaweed extract can enhance the antioxidant
capacity of plants and reduce the damage caused by environmental stress.
4. Environmental Protection and Sustainability
As an organic fertilizer, seaweed extract emphasizes sustainability and environmental friendliness.
It does not contain harmful chemicals and will not have a negative impact on the environment during use.
Meanwhile, seaweed is a rapidly growing biological resource that does not cause significant damage to the ecological environment during collection,
contributing to the development goals of green agriculture.
Application fields of seaweed extract fertilizer
Application fields of seaweed extract fertilizerSeaweed extract fertilizer can be widely used in the cultivation and management of various crops, including but not limited to:-Fruits and vegetables: especially used during the fruit swelling and bud formation stages, can significantly improve yield and quality.-Grain crops: The use of seaweed extract can improve the stress resistance of grain crops such as wheat and rice.-Flowers and ornamental plants: Adding seaweed extract to soil can promote the growth of flowers, increase flowering rate, and enhance the brightness of flower colors.-Lawn and Horticulture: Suitable for maintaining home gardens and public green spaces, it can improve the growth status of lawns.How to use seaweed extract fertilizer
How to use seaweed extract fertilizer
There are multiple ways to use seaweed extract fertilizers, which can be flexibly applied according to different crops and growth stages.
Here are several common usage methods:
1. Foliar spraying
During critical stages of plant growth, such as flowering and fruiting, seaweed extract can be applied by foliar spraying,utilizing the plant's stomata for rapid absorption.
It is usually recommended to spray in the early morning or evening when the temperature is low, to avoid direct sunlight causing the liquid to evaporate too quickly.
2. Root watering
Adding seaweed extract fertilizer to the soil can effectively promote root growth and improve soil quality. Mix an appropriate amount of seaweed extract with water,
and then water the roots of the plants. Generally, using 1-2 times a month yields the best results.
3. Apply to the soil
Mixing seaweed extract fertilizer into the soil before cultivation can provide a good nutritional foundation for crop growth.
This method is suitable for use before sowing or during the seedling stage, and can effectively improve the overall condition of the soil.
Fulvicmax – Mineral Fulvic Acid Solution for Tomato Nutritio...
Fulvicmax is a high-purity mineral-sourced fulvic acid formulation designed to optimize nutrient efficiency and soil-plant interaction in intensive cropping systems.
Derived from natural leonardite and 100% water-soluble, it plays a critical role in improving nutrient bioavailability, promoting early root vigor, and enhancing crop resilience.
Proven Agronomic Advantages for Tomato Cultivation:
1.Chelates macro & micronutrients, improving translocation and uptake efficiency, especially under pH stress or saline soil conditions.
2.Enhances early-stage root and shoot development, supporting robust vegetative growth and uniform flowering.
3.Increases fruit set and size, while improving soluble solids (°Brix), firmness, and post-harvest quality.
4.Improves abiotic stress tolerance, including drought, salinity, and heat, common in protected and open-field tomato production systems.
5.Stimulates rhizosphere microbiota, contributing to long-term soil structure improvement and nutrient cycling.
Compatible with fertigation systems, foliar application, and NPK compound blends,
Fulvicmax is suitable for integration into high-value crop nutrition programs, including tomato, pepper, cucumber, melon, and strawberry.

Application & Recommended Dosage
1.Field crops (such as rice and corn): 450-675kgs/ha, mixed with farmyard manure or compound fertilizer and tilled into the soil.
2.Cash crops (such as vegetables and fruit trees): 675-980 kg/ha, dig trenches around the root system and bury the fertilizer.
Fruit trees can be adjusted according to the age of the tree (2-5 kg per adult tree).
3.Poor soil or compacted plots: The dosage can be increased by 20%-30%, and the effect is better when used with organic fertilizer.

The application methods of 100% Water Soluble Potassium Humate
Application method & recommend application dosage:
1. Foliar Spraying
Concentration: Dilute 800–1000 times (i.e., add 15–20 g potassium humate to 15 Litre water), and spray evenly on both sides of leaves.
Timing: Seedling stage, before/after flowering, young fruit stage, before adverse conditions (drought, low temperature), or post-disaster recovery.
Note: Avoid high-temperature periods; spray in the evening for better absorption.
Can be mixed with neutral/weakly acidic pesticides (e.g., fungicides, foliar fertilizers) to reduce labor costs.
2. Root Drenching
Concentration: Dilute 1000–1500 times, and apply 200–500 mL of solution per plant, focusing on the soil around the roots.
Application: During transplanting recovery or when roots are damaged (e.g., waterlogging, root rot), to promote new root growth and restore plant vigor.
3. Seed Soaking/Root Dipping (Nursery Stage)
Seed Soaking: Dilute 500–800 times, soak seeds for 6–12 hours, then air-dry before sowing to improve germination rate and seedling robustness.
Root Dipping: Dilute 300–500 times, soak seedling roots for 10–20 minutes to reduce transplanting stress and enhance stress resistance.
Precautions
Mixing Taboos: Avoid mixing with strongly acidic or strongly alkaline fertilizers/pesticides to prevent chemical reactions that reduce efficacy.
Dosage Adjustment: Adjust dosage based on soil fertility, crop type, and growth stage (reduce for seedling stage, increase for fruit expansion stage).
Their Application Methods
Water Quality: Use clean freshwater for dilution. If water is highly hard (high in calcium/magnesium ions), let it settle first and use the supernatant.
