Here is just some of the components in the A1Lawn Ultimate Lawn Seaweed Extract:

  1. Alginates - improve soil structure; increasing humates, forming crumb structure, increasing soil aeration & aerobic bacteria, increases moisture retention.  With mannitol a carbohydrate, trace elements (present in seaweed and the soil) are chelated and made available to plants.
  2. Amino acids - (alanine, valine, glycine, isoleucine, serine, tyrosine & stress protecting amino-betaines); these Natural L-isomers are used by plants directly in the production of proteins. 
  3. Auxins - Plant hormones are essential for plant body development, enabling a plant to react to external conditions.  Auxins stimulate cell elongation & promote root initiation.
  4. Cytokinins - promote cell division and plant growth.
  5. Gibberellins - regulate plant growth & enzyme production, breaking dormancy and stimulating cell elongation causing plants to grow taller.
  6. Vitamins - A, B1, B2, B3, B5, B12, C, D, E, K, choline & carotene.
  7. Betaines - aid plants to cope with stresses such as cold, heat, water deficient or high salt conditions and increases the tolerance of plants to abiotic stress.
  8. Fucoidan - provides plant protection in strong sunlight and harsh environments.
  9. Laminarin - accelerates seed germination and plant growth and elicits defense response in plants reducing infection of the plant by various diseases.
  10. Mannitol - increases trace element availability, increases a plants tolerance to salt and osmotic stress and has a role in a plants response to attack from pathogens; reducing biotic & abiotic stresses.  Mannitol decomposes readily & unlike cellulose, doesn’t immobilise Nitrogen.
