Brewing quality products since 1996 AgriSea NZ Ltd is a multi-award winning sustainable New Zealand company, family owned and operated. The company produces Seaweed Soil, Foliar, Turf, Pasture and Animal Health concentrates for Agriculture and Horticulture.

The New Zealand native seaweed species (Ecklonia radiata) is batch-brewed with specially selected essential herbs for up to 90 days. The natural brewing process eliminates the use of processing with heat, chemicals, freezing or dehydration that might ‘denature’ the sensitive nutrient balance, allowing the natural growth stimulants and micro-nutrients to be released in an active form to enhance soil and plant health. AgriSea’s natural brewing methods are unique for commercial production.

Seaweed is one of the most complex materials available containing almost every known element.
Its vast range of minerals, trace elements, mannitols, alginates, amino acids, naturally occurring growth hormones, and antibodies etc provide a nutrient ‘feast’ for berries.

A fertile productive soil is a biologically active soil in which large microbial populations flourish.

AgriSea Soil Nutrition feeds and increases the soil microbial population building the precious humus layer which is the nutrient storehouse of the soil aiding disease prevention and water retention

AgriSea Foliar Nutrition provides nutrients directly to the crops and & helps to prevent leaf borne disease and insect attack.
