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.
Khumic E+ active humic acid Granular natural soil conditioner based on high active Leonardite. It is organic chelator and natural plant growth stimulant.
Product Advantages
Khumic E+ active humic acid Granular is ideally suitable for addition with granular fertilizers, such as Urea.
With prominent effect to release the locked phosphate by some ion such as Fe3+, Al3+,
also can slow-release nitrogen fertilizer to promote the function of NPK fertilizers.
Used as multi-functional compound fertilizer, combined with Nitrogen and Phosphorus, Mainly used as basal fertilizer, top dressing, seed fertilizer.
.Has excellent blending capabilities when mixed with MAP,ammonium sulfate and KCL based fertilizers. Ideal for broadcast or in-furrow application
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.
Khumic N+ is a humic-acid-enhanced nitrogen fertilizer engineered to meet the specific physiological and agronomic demands of Vaccinium spp.
(blueberries). Formulated for high-efficiency nitrogen delivery in acidic, low-C.E.C. soils, Khumic N+ improves nutrient availability,
supports fine-root development, and enhances soil structure—all critical factors for optimizing blueberry yield and fruit quality.
Technical Advantages in Blueberry Systems:
1.Enhanced Nitrogen Efficiency: Stabilizes nitrogen in the root zone, reducing leaching loss common in coarse-textured soils typically used in blueberry production.
2.Root-Zone Activation: High humic acid content stimulates rhizosphere activity, improving fine root proliferation and nutrient absorption.
3.Optimized Soil-Plant Interface: Promotes better soil aggregation and moisture retention—essential for shallow-rooted blueberry crops.
4.Improved Berry Set & Uniformity: Supports hormonal balance and nutrient flow during flowering and fruit set stages, contributing to more uniform berry sizing.

Looking to boost watermelon yield, sweetness, and resilience?
Fulvicmax is a premium organic fertilizer powered by mineral-source fulvic acid,
specifically designed to enhance nutrient efficiency and root development in fruit crops like watermelon.
Derived from high-grade leonardite, Fulvicmax contains highly active fulvic acids that improve nutrient solubility and mobility
in soil—leading to better uptake of nitrogen, phosphorus, potassium, and trace elements through roots.
This results in stronger root systems, faster early-stage growth, and healthier vines with improved flowering and fruit set.
In watermelon cultivation, Fulvicmax delivers clear advantages:
✔Accelerates fruit expansion and uniform sizing;
✔Increases sugar content for sweeter taste and better market value;
✔Enhances drought tolerance during critical fruiting stages;
✔Improves soil texture, aeration, and microbial activity.
Fulvicmax is suitable for basal application and mechanical broadcasting, especially in sandy or saline-alkaline soils where
watermelon ias typically grown. It also helps unlock locked nutrients, reduces fertilizer losses, and supports sustainable production.
In the pursuit of premium grape quality, more growers are turning to Alga 800(seaweed extract)—a high-performance biostimulant derived from 100% natural
seaweed species like Ascophyllum nodosum and Laminaria. Rich in bioactive compounds such as alginic acid, trace elements, and plant hormones,
Alga 800 strengthens grapevines from the very beginning.
By stimulating early root development and improving nutrient uptake, Alga 800 lays a solid foundation for vigorous canopy growth and balanced shoot development.
During the flowering stage, it promotes better bud formation and fruit set, reducing the incidence of flower drop or malformed clusters.
As grapes mature, its influence becomes even more evident—enhancing sugar accumulation, boosting pigment intensity, and improving overall fruit uniformity.
Moreover, Alga 800(seaweed extract)helps grapes withstand environmental stress like heat and drought,
while also reducing post-harvest shrinkage and extending shelf life—an added value for export-quality crops.
To adapt to diverse farming practices, Khumic offers Alga 800 in Powder, Flakes, and Micro Granule forms,
ensuring compatibility with both foliar spray and fertigation systems. Whether for organic or conventional vineyards, Alga 800(seaweed extract)offers a natural edge in performance.
