Seaweed A Clear Picture

For the highest elemental content seaweeds must be: • Harvested live • Harvested at the correct time in the growth cycle • Processed immediately • Processed without excessive heat or chemical • Once processed stored correctly

Nutritional and PGR properties of seaweed It is often claimed that the seaweeds sourced from colder waters contain more nutrient and plant growth regulators. However it is more the stage of growth at which the seaweed is harvested that determines the level of nutrient and PGR present in the harvested seaweed. Also the way the raw seaweed is processed is also important.

The main methods of processing seaweed are: • Alkaline extraction • Cold compression (which can be followed by low temperature drying) • Dried seaweed is ground in to a fine powder • Fermentation All methods produce a good finished product, however if the seaweed is dried or refined using heat many properties can be lost

Common examples of these methods available in NZ: • Goemar BM486 – French seaweed mixed with added nutrient. Sold internationally as a fertiliser with seaweed, sold in NZ as ‘Seaweed Cream’ • AgriSea – fermentation • Kelpak – cellburst with added MAP With liquids it is important to know how they are made and if imported check out international labels. Many contain added nutrient in particular nitrogen so it is important to know the NPK content.

• Consistent blend of cold water Northern Hemisphere and sustainably farmed brown seaweeds grown and harvested in pollution free waters. • Alga 600 ™ contains three seaweed species, Sargassum, Laminaria and Ascophyllum Nodosum the primary seaweed in Alga600, which is sourced from Norway. • Alga 600 ™ is created using low temperate, fast drying cell burst technology through alkaline extraction • 1kg per ha

• Orca Plus™ is a liquid plant stimulant for foliar application. • 2-3 L per with a water rate of 1000L per ha. • Guaranteed Analysis 1N, 2P, 4K. • 30% Alga600 seaweed extract powder concentrate. • Triacontanol, a natural PGR, stimulates growth and nutrient uptake.

Ascophyllum Nodosum Sourced from the coasts from 40 latitude in the northern hemisphere Ascophyllum Nodosum is a standard base seaweed used either as a product on its own or as a base for liquid seaweeds and nutrient products.

Laminaria spp Sourced from the coasts around Indonesia and China where it grows wild and in farms. It also grows in the same waters as Ascophyllum Nodosum. Commonly known as “Kelp” Laminaria contains Polysaccharides. Polysaccharides aid the plants immune system and encourage disease resistance.

Sargassum spp Sourced from all over the world. As a pest invasive species of seaweed for many countries its harvest is often not restricted. However it is also farmed for food and medicinal purposes in particular areas of the world. In particular off the costs of China, Indonesia and Korea. Sargassum is rich in Alganic Acid and Cytokinins

Foliar applications Seaweeds contain natural Plant Growth regulators which can help: • Trigger growth in plants • Aid in even flower development • Increase: • carbohydrate production in plants • root development • the plants ability to cope with stress Seaweeds contain natural compounds such as Alganic acid and Polysaccharides which: • Aid the plants natural defense system • Inhibits some mite species (S. D. Hankins and H. P. Hockey , 1990)

Soil applications Used as a soil drench seaweeds can: • Increase root development (Sangeetha, V and Thevanathan, R*, Journal of American Science 2010) • Increase soil microbial action • Used to clean up soils contaminated with heavy metals • Increase seed germination and reduce establishment stress (G. Thirumaran, M. Arumugam, R. Arumugam and P. Anantharaman, American-Eurasian Journal of Agronomy 2009) However it is important to time a soil application of seaweeds with a solid fertiliser application or in plant dormancy. As when seaweeds are applied to the soil they temporarily drop the Nitrogen levels down for up to six weeks. This occurs as the microbes require additional nitrogen to multiply. This nitrogen is then released later when this process is finished.
