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 known to man and contains a vast range of minerals, trace elements, mannitols, alginates, amino acids, naturally occurring antibodies and plant growth hormones that provide a nutrient ‘feast’ for fruit trees.

A fertile and productive soil is a biologically active soil in which large microbial populations flourish, building the precious humus layer which is the nutrient storehouse of the soil that aids disease protection and moisture retention.

AgriSea Soil Nutrition feeds and increases the soil microbial population, while promoting the development of a strong and healthy root system.

AgriSea Foliar Nutrition provides nutrients directly to the tree in a form that is readily absorbed.

An experienced NZ grower reports

“Heritage Farm has been applying AgriSea Soil & Foliar concentrates for four seasons now and every year we see more benefits – or to put it another way, less problems. We have noticed that our apples have better than normal taste, and they store well.

We also use both the Soil & Foliar brews on kiwifruit, plums and asparagus and have noted similar results to the apples. These benefits have become more apparent every year and we will continue to use these products as part of our management practices”
