Seaweed extracts are among the most valuable natural biostimulants in modern plant nutrition programs. With their high polysaccharide, natural growth regulator, and alginic acid content, they protect plants against stress and support development. RapidAlg is a seaweed-based fertilizer that delivers these benefits in a foliar-applied formula. This guide explains its content, benefits, and how to use it.
What Is RapidAlg?
RapidAlg is a seaweed-based foliar fertilizer rich in polysaccharides, natural growth regulators, and alginic acid. Its guaranteed content is:
- Total Organic Matter: 50%
- Organic Carbon: 25%
- Total Nitrogen (N): 3%
- Water-Soluble Potassium (K2O): 12%
- Alginic Acid: 2%
- Free Amino Acids: 3% · pH: 6.5
Benefits of Seaweed Fertilizer
- Stress protection: shields plants against heat, drought, and environmental stress.
- Tissue resistance: improves resilience against disease.
- Root and fruit development: natural growth regulators support rooting and fruiting.
- Trace-element uptake: alginic acid's chelating effect eases micronutrient uptake.
- Overall vigour: high potassium supports fruit quality and plant resistance.
Why Is Alginic Acid Important?
Alginic acid is a natural polymer derived from seaweed. It increases the soil's water-holding capacity, retains nutrients in the root zone, and stimulates root development, improving nutrient-use efficiency.

How to Apply RapidAlg
RapidAlg is applied foliarly. Apply in the early morning (6:00-9:00) or late afternoon (after 5:00 PM), ensuring full leaf coverage, and avoid application in high heat. For the exact dose tailored to your crop and growth stage, contact the Agrorun technical team. Regular application is recommended during periods of increased environmental stress and during fruit development.
Which Crops Benefit?
It can be used on a wide range of crops, especially vegetables, fruit, and vineyards, with notable results in stressed and high-value produce.
Combining with Other Products
RapidAlg can be rotated with AminoWork for protein synthesis and stress management, and planned alongside Power NPK for balanced macronutrition. This combination strengthens both the plant's nutrition and its stress resistance.
Seaweed fertilizers are a sustainable tool that supports plant resistance and yield from a natural source, without adding chemical load.
