Slow rooting after transplanting, uneven growth during drought or salinity, and gaps in nutrition from flowering to fruit expansion are common field problems. SEAWEED 100 combines >40% alginic acid, >2% mannitol and >3% combined Ca/Mg/S/B in green micro granules. Water solubility is 100% and pH is 8–9. The formula brings root-zone support, abiotic-stress management and secondary/micronutrient supplementation into one fertigation-friendly input for fruit, vegetable and field crops.
Alginic acid is a hydrophilic seaweed polysaccharide that interacts with water and nutrient ions, helping manage the root-zone environment and support lateral-root growth. Mannitol, a seaweed-derived polyol, is associated with osmotic balance and antioxidant processes and can complement crop care during drought, salinity or heat stress. These are biostimulant functions; field response still depends on crop, environment and use rate.
Ca supports cell walls, growing points and fruit tissues; Mg is central to chlorophyll and photosynthesis; S forms part of sulfur-containing amino acids and proteins; B supports cell walls and pollen-tube development. The >3% guarantee covers the four elements together, not >3% of each. Use soil or tissue tests to target deficiencies alongside a balanced NPK and irrigation program.
Micro granules address a handling trade-off: they disperse more readily than large flakes under comparable mixing conditions and create less airborne dust during handling than fine powders. They are easy to measure and add to a mixing tank. Fully dissolve with agitation before feeding the irrigation system; actual dissolution time varies with water temperature, mixing and loading.

Use the existing crop-rate table and local label to plan applications after transplanting, during root growth, before flowering, at early fruit development or after abiotic stress. Fully dissolve in a mixing tank with agitation. Test tank compatibility before combining with other fertilizers or pesticides; diagnose individual Ca/Mg/S/B needs from soil or tissue tests.

Three complementary components support roots, abiotic-stress response and crop nutrition, while the micro-granule form improves handling and dissolution.
Its water-loving and ion-interacting properties can help manage moisture and nutrient conditions around roots and support new and lateral root development.
This seaweed polyol is associated with osmotic and antioxidant processes, complementing crop management during drought, salinity and heat.
Ca supports growing tissue and fruit structure; Mg chlorophyll; S protein formation; B pollen tubes and cell walls. The >3% specification is their combined total.
Seaweed polysaccharide, mannitol and mineral nutrition can be delivered together, simplifying the transition from transplant recovery to flowering and fruiting.
Micro granules disperse more readily than large flakes and raise less dust than fine powder when handled; 100% water solubility supports premixing for fertigation.
Uniform granules are easy to weigh and add gradually to water, reducing clumps and local high concentration when fully dissolved before application.
Ihumate is backed by globally recognized certifications.
