    Product Overview:

    Liquid NPK + Humic Acid is a premium, water-soluble, liquid fertilizer that combines essential macronutrients (Nitrogen, Phosphorus, and Potassium) with bioactive humic substances derived from high-quality leonardite. This blend is designed to improve nutrient absorption, enhance soil health, stimulate root development, and promote plant vigor throughout all growth stages.

    Humic acid acts as a natural chelator, increasing the availability of nutrients and improving the cation exchange capacity (CEC) of soils. This synergistic formulation ensures both immediate and long-term benefits for crops.


    Key Benefits:

    • ✅ Enhanced Nutrient Uptake: Humic acid improves the absorption of NPK and other minerals

    • ✅ Stimulates Root Growth: Promotes stronger, deeper roots and better drought resistance

    • ✅ Soil Conditioner: Increases microbial activity and improves soil texture and water retention

    • ✅ Boosts Crop Yield and Quality: Improves flowering, fruiting, and chlorophyll production

    • ✅ Stress Resistance: Helps plants cope with drought, salinity, and disease pressures

    • ✅ Versatile Application: Suitable for foliar spray, fertigation, soil drenching, and drip irrigation


    Application Recommendations:

    Crop Type Foliar Spray Soil/Drip Irrigation
    Vegetables 2–4 mL/L of water 10–25 L/ha per application
    Fruits 3–5 mL/L of water 15–30 L/ha per application
    Field Crops 2–3 mL/L of water 10–20 L/ha per application
    Ornamentals 2 mL/L of water 5–10 L/ha per application
    Greenhouse/Hydroponics 0.5–1.5 mL/L 2–5 L/1000 m² per application

    Frequency: Apply every 10–15 days during active growth stages
    Compatibility: Compatible with most agrochemicals. Conduct a jar test before mixing


    Storage & Handling:

    • Store in a cool, dry, and well-ventilated area

    • Keep container tightly closed and away from direct sunlight

    • Shake well before use

    • Use gloves and eye protection during handling


    Target Uses:

    • ✅ Open-field and greenhouse cultivation

    • ✅ Hydroponic systems and vertical farming

    • ✅ Fruit orchards, vineyards, plantations

    • ✅ Turfgrass, landscaping, and nurseries

    • ✅ Suitable for organic and conventional agriculture


    Conclusion:

    Liquid NPK + Humic Acid Fertilizer is a high-efficiency, dual-action solution for modern agriculture. It not only supplies essential nutrients in a readily available form but also conditions the soil to sustain long-term productivity. Ideal for improving crop yield, root vitality, and plant resilience—making it an excellent addition to any nutrient management program.

    ECHEMI Editorial Reference
    Urea is a powerful protein denaturant via both direct and indirect mechanisms. A potent emollient and keratolytic agent. Used as a diuretic agent. Blood urea nitrogen (BUN) has been utilized to evaluate renal function[3]. Widely used in fertilizers as a source of nitrogen and is an important raw material for the chemical industry.
    Urea appears as solid odorless white crystals or pellets. Density 1.335 g /cc.

    Urea appears as solid odorless white crystals or pellets. Density 1.335 g /cc. Noncombustible.|Urea is a carbonyl group with two C-bound amine groups. The commercially available fertilizer has an analysis of 46-0-0 (N-P2O5-K2O). It has a role as a flour treatment agent, a human metabolite, a Daphnia magna metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite, a mouse metabolite and a fertilizer. It is a monocarboxylic acid amide and a one-carbon compound. It derives from a carbonic acid. It is a tautomer of a carbamimidic acid.|A compound formed in the liver from ammonia produced by the deamination of amino acids. It is the principal end product of protein catabolism and constitutes about one half of the total urinary solids.|Urea is a nitrogenous compound containing a carbonyl group attached to two amine groups with osmotic diuretic activity. In vivo, urea is formed in the liver via the urea cycle from ammonia and is the final end product of protein metabolism. Administration of urea elevates blood plasma osmolality, resulting in enhanced flow of water from tissues, including the brain, cerebrospinal fluid and eye, into interstitial fluid and plasma, thereby decreasing pressure in those tissues and increasing urine outflow.

    Reactivity Profile:

    UREA is a weak base. Reacts with hypochlorites to form nitrogen trichloride which explodes spontaneously in air [J. Am. Chem. Soc. 63:3530-32]. Same is true for phosphorus pentachloride. It reacts with azo and diazo compounds to generate toxic gases. Reacts with strong reducing agents to form flammable gases (hydrogen). The heating of improper stoichiometric amounts of urea and sodium nitrite lead to an explosion. Heated mixtures of oxalic acid and urea yielded rapid evolution of gases, carbon dioxide, carbon monoxide and ammonia (if hot, can be explosive). Titanium tetrachloride and urea slowly formed a complex during 6 weeks at 80° C, decomposed violently at 90 C, [Chem. Abs., 1966, 64, 9219b]. Urea ignites spontaneously on stirring with nitrosyl perchlorate due to the formation of the diazonium perchlorate. Oxalic acid and urea react at high temperatures to form toxic and flammable ammonia and carbon monoxide gases, and inert CO2 gas [Von Bentzinger, R. et al., Praxis Naturwiss. Chem., 1987, 36(8), 41-42].
