5. Mifica


ALGA-SOL Cold Press Concentrate Seaweed Extract Ascophyllum Seaweed Extract 5Ltr Biostimulant Fertiliser Fertilizer Seaweed Plant Feed Organic Fertiliser Fertilizer

Mifica #ad - Developed and used by professionals: alga-sol seaweed extract was developed by a team of leading scientists after a 6 year study on seaweed extracts and their extraction methods. Many seaweeds on the market are high in pH due to their chemical extraction. All of these compounds are found naturally in Ascophyllum nodosum and retain their maximum levels in our unique Cell Harvest Technology process.

In the uk our extract is used every season on Gleneagles Golf Course as well as 60% of the UK Premier League Football Grounds. Due to our low temperature extraction process, functional polysaccharides alginates as well as bioactives including cytokinins, natural anti-oxidants, auxins, ALGA-SOL is high in naturally chelated micronutrients, mannitol and gibberellins. The cold-press process involves the seaweed being passed through a concentrated point of pressure similar to the extraction of virgin olive oil. Store in a cool & dry place out of direct sunlight.

This ensures that all natural bioactives are extracted and preserved before they degrade. After hand harvesting the Ascophyllum seaweed is transported and processed via our extraction plant within 6 hours of leaving the sea. Over the years we have gained a large following by several industries and we currently supply a number of companies who manage some of the leading sportsgrounds Globally. The dangers of using an alkaline based seaweed extract include the onset of diseases such as scab in potatoes. Seaweed extract is manufactured via cold-press extraction methods.
