Listing Detail Tabs

Natrakelp (Tasmanian Bull Kelp) has been widely used in Australia for plants, soil, livestock and poultry since 1987. Whole kelp is liquefied and fermented, using modern cold-processing, to produce one of the world’s richest and most effective sources of pure minerals and micronutrients for use in agriculture and horticulture.

Natrakelp® is the pinnacle of seaweed concentrates and comes in 1L bottles for home gardeners, as well as cost-effective larger quantities for horticulture, viticulture and agriculture use.

1L of Natrakelp® for Plants concentrate can produce 250 litres of biostimulant or foliar spray. Natrakelp’s difference from other currently available liquid seaweed products is that ALL ALGINATES ARE RETAINED in the kelp, to feed plants and unlock other nutrients in the soil, producing optimum plant growth and health.

When used in conjunction with a herbicide, Natrakelp® will significantly reduce eradication time. Natrakelp allows the plant to take up anything that comes into contact with it, whether it be herbicide or residual fertiliser in the soil.

Natrakelp® is a unique product which has been proven to out-perform all other Liquid Seaweed products currently on the New Zealand market.

Natrakelp® Liquid Seaweed concentrate has demonstrated increased yields in small and broadacre crops, turf and pasture, horticulture, ornamental and home gardens and also provides significant health benefits for horses, pigs, poultry and livestock.
