Angus Seaweed Meal

Our Angus Seaweed Meal is 100% Ascophyllum nodosum harvested from the Atlantic Ocean.

• Promotes stress resistant healthy sward
• Increases soil fertility
• Reduces requirements for chemical fertiliser
• Useful source of organic carbon
• Contains carbohydrates, amino acids, protein and vitamins all essential for healthy soils
• Ideal content of N & K and lower in P than many of the typical NPK ratios in chemical fertilisers
• Carbohydrates in Ascophyllum nodosum improves aeration & soil structure, especially in clay soils.
• Excellent moisture retention properties

Angus Seaweed Meal top dress, turf feed and soil conditioner also contains the following:

Alginates, present in seaweed meal at levels of between 15% & 26% which increases microbial populations. It is well documented that the soil health and associated plant growth is directly proportional to the presence or absence of soil microbes. Alginates also absorb large volumes of water thus increasing the moisture in the soil.

Amino acids are a major constituent of Angus Seaweed Meal and are the essential, basic components of proteins. A range of plant hormones including cytokinins and biochemical compounds are also abundant in Angus Seaweed Meal. These substances significantly increase the protein content in grass and stabilise leaf proteins.

Cytokinins are involved in many plant processes, including cell division, shoot and root morphogenesis. Cytokinins regulate axillary bud growth and apical dominance. The “direct inhibition hypothesis” posits that these effects result from the cytokinin to auxin ratio. This theory states that auxin from apical buds travels down shoots to inhibit axillary bud growth. This promotes shoot growth, and restricts lateral branching. Cytokinin moves from the roots into the shoots, eventually signaling lateral bud growth. Simple experiments support this theory. When the apical bud is removed, the axillary buds are uninhibited, lateral growth increases, and plants become bushier. Applying auxin to the cut stem again inhibits lateral dominance.

Angus Seaweed Meal is used to condition soils; as it breaks down it gently releases nutrients. Alginates, which are unique to seaweeds act to improve the structure of clay soils whilst increasing the water holding capacity of sandy soils. Seaweed is rich in trace elements essential to plants. Angus Seaweed Meal feeds lightly and will not produce excessive growth.
