Here are just some of the components in the A1Lawn Ultimate Lawn Seaweed Extract:
- Alginates – improve soil structure; increasing humates, forming crumb structure, increasing soil aeration and aerobic bacteria, increases moisture retention. With mannitol (a carbohydrate), trace elements (present in seaweed and the soil) are chelated and made available to plants.
- Amino acids – (alanine, valine, glycine, isoleucine, serine, tyrosine and stress-protecting amino-betaines); these natural L-isomers are used by plants directly in the production of proteins.
- Auxins – plant hormones essential for plant body development, enabling a plant to react to external conditions. Auxins stimulate cell elongation and promote root initiation.
- Cytokinins – promote cell division and plant growth.
- Gibberellins – regulate plant growth and enzyme production, breaking dormancy and stimulating cell elongation, causing plants to grow taller.
- Vitamins – A, B1, B2, B3, B5, B12, C, D, E, K, choline and carotene.
- Betaines – aid plants in coping with stresses such as cold, heat, water deficiency or high salt conditions, increasing their tolerance to abiotic stress.
- Fucoidan – provides plant protection in strong sunlight and harsh environments.
- Laminarin – accelerates seed germination and plant growth and elicits defence responses in plants, reducing infection by various diseases.
- Mannitol – increases trace element availability, enhances tolerance to salt and osmotic stress, and supports a plant’s response to pathogen attack, reducing biotic and abiotic stresses. Mannitol decomposes readily and, unlike cellulose, doesn’t immobilise nitrogen.
