Synthetic Fertilisers

Straight fertiliser is a term commonly used to describe fertilisers which contain only one of the macronutrients, such as Urea (Nitrogen) or Muriate of Potash (Potassium).

Many ‘straight’ fertilisers, such as Suphate of Ammonia also contain other essential nutrients like sulphur.

Blended Fertiliser

Blended fertiliser is the term  used to describe fertilisers that are a mix of or more ‘straight’ fertilisers. Examples of blended fertilisers are CK 88, GF 301 and GF 303.

Many fertiliser blends contain different ratios of NPK to suit different stages of plant growth.

Compound Fertiliser

Compound fertilisers are manufactured by a chemical reaction and will contain two or more major nutrients. Unlike blended fertilisers each granule is a simular size and contains the same nutrients. Examples of compound fertilisers include Nitrophoska Special and di-ammonium phosphate (DAP).

Organic Fertilisers

Organic fertilisers are manufactured using animal or plant by-products, many are certified organic. Examples of organic fertilisers includes Blood & Bone, Poultry Manure and Seasol (seaweed).

Most Organic Fertilisers are slow releasing as the nutrients need to be converted into a form which the plant can uptake them. Besides supplying quantities of NPK, sulphur and some trace elements, they also provide organic matter to improve soil structure.

Slow-release Fertiliser

Slow-release fertilisers are fertilisers which are not readily water soluble and will usually have a special coating. Examples of slow release fertilisers include Osmocote and Troforte M.
