Seasol is only really a nitrogen fertiliser... useful as a foliar spray... and some people put it into the tank as an extra "nitrogen" source to supplement the fish nutrients.

Seasol is a dynamic growth stimulant and plant tonic, it is not by definition a fertiliser. Scientific trials and field observations over many years have proven its value as a means of promoting healthy vigorous growth in plants, improving resistance to insect and fungal attack, and reducing the symptoms of stress from excessive heat, frost damage and transplanting.

The manufacturing process used to extract the liquid concentrate is also unique. Seasol is the only seaweed extract in Australia to have the naturally occurring growth stimulants scientifically identified, and this work, conducted by the Australian National University, has been published and is recognised worldwide.

WHAT MAKES SEASOL DIFFERENT FROM A FERTILISER ?

Nitrogen based fertilisers are often highly soluble and the plant cannot regulate how much it takes up. If confused nitrogen stimulates extensive growth which results in a weakening of the cell wall if used too frequently, or at too higher rate.

By contrast, Seasol promotes cell division as well as cell elongation and this, along with thicker cell walls, renders the plant much less prone to sucking insects and fungal pathogens, which must pierce the cell to inflict their damage.

Another difference between Seasol and a fertiliser, is that Seasol is a balanced formulation containing many trace elements, amino acids, vitamins and other compounds essential for plant growth.

Every known trace element is found in Bull Kelp.

Maxicrop Seaweed plant Food Concentrate is a general purpose
plant food for application to leaves or roots. The seaweed extract
contains over 60 trace elements, minerals and naturally occurring
growth factors that are important for plant growth and
development. The seaweed is fortified with added Nitrogen,
Phosphorus and Potassium.

How often can I apply Seasol?

A one-off Seasol treatment will provide significant benefits, however regular applications (eg. fortnightly or monthly) produce best results. Unlike fertilizers, Seasol can be applied all year round, even in winter and at the height of summer.

What is the difference between Seasol and PowerFeed?

Seasol is made from pure Bull Kelp. It is not, by definition, a fertiliser (as it contains only marginal nitrogen and phosphorus levels), however it is a dynamic stimulant which improves the root system and increases the reproductive capacity, thereby increasing the number of flowers per plant as well as the flowering season.

PowerFeed is a fertiliser. It has a fish base which is fortified with nitrogen, phosphorus and potassium. The ratio of which is 12:1.4:7 respectively. PowerFeed also contains dynamic soil improvers in the form of humic acids. These compounds work at very low rates and are literally like adding liquid composts to the soil. As well as being a quality fertiliser, PowerFeed is also a clay breaker. It stimulates beneficial soil microbial activity and markedly reduces leaching in sandy soils.

So whats in powerfeed that is not in maxicrop?
