Frequently Asked Questions

 

What is a fertiliser?

Fertiliser is generally regarded as material, the primary purpose of which is to provide nutrients to plants. Plant nutrients are normally broken down into macro materials (Nitrogen, Potassium and Phosphorous) which are applied in large volumes. Secondary materials (Calcium, Magnesium and Sulphur) along with a broad range of micro or trace elements are applied in smaller amounts but are also essential for good plant nutrition.

What is a biostimulant?

The European Biostimulant Industry Council ( EBIC) have a working definition as follows “Plant biostimulants contain substance(s) and/or micro-organisms whose function when applied to plants or the rhizosphere is to stimulate natural processes to enhance/benefit nutrient uptake, nutrient efficiency, tolerance to abiotic stress, and crop quality”.

What is a plant protection product?

A plant protection product is often referred to as a pesticide and is something that prevents, destroys, or controls a harmful organism (‘pest’) or disease, or protects plants or plant products during production, storage and transport.

What are seaweed extracts?

Seaweed extracts are products that are derived from one of the 9500 different seaweed species for use as either a fertiliser or biostimulant depending on the properties of the extract. The extraction process can vary from producer to producer but all have the common purpose of releasing the minerals and organic compounds contained in the seaweed. Different species and extraction processes means that no two extracts are identical though they may contain common ingredients with gives similar effects in given situations.

 

How do I compare seaweed extracts?

Comparing seaweed extracts is not always easy as the information regarding the content is frequently presented in different ways. The best starting point is to bring everything back to a simple common denominator – for example 1 litre and ensuring all values are given relative to this 1 litre volume. Ultimately the product efficacy is what matters most and due to the complexity of seaweed extracts a simple growth trial is the best method of evaluation.

How do I use seaweed extract?

Seaweed extract is not a replacement for good crop husbandry, but rather an additional input that when used as part of a good crop management strategy can increase crop yield, condition and return on investment to the grower. Seaweed extract is generally regarded as being compatible with most other farm inputs and can be applied in most tank mixes. It is strongly recommended that a “jar test” be carried out to verify compatibility prior to mixing larger quantities of different materials in a tank.
