Trust in Proven Performance

Choosing Osmocote coated fertilisers means choosing proven performance for the best results for your crops. A coated fertiliser must do what you expect from it. It needs to be predictable and consistent in its performance for good results. Over the decades, Osmocote has proven to be worthy of your trust. Our years of experience, tried and tested coatings, pure and best quality raw materials used in our products and continuous quality control are the pillars of this trust. This is what you can expect from us at ICL Specialty Fertilisers: guaranteed high-quality crops and the best return on investment for your business.

The quality of your plants is guaranteed thanks to optimum growth. Plants grow better because Osmocote provides them with the nutrients they need exactly at the moment they need them. This gradual nutrient supply ensures that plants experience less disease pressure and can grow into vital, healthy specimens. The plants even keep their vitality and health when they are delivered to the consumer. This is yet another benefit that comes from the continued release of nutrients from Osmocote fertilisers… customer satisfaction!

The Osmocote working principles

Osmocote are coated fertilisers containing nitrogen, phosphorus and potassium.

 

Every granule is covered by an organic resin coating that regulates the daily release of nutrients to the plant.	Granules contain NPK, B, Cu, Fe, Mn, Mo and Zn.	Water penetrates the coating and dissolves the nutrients inside the granule.	Osmotic pressure releases the dissolved nutrients through the granule coating.	Influenced by temperature, the nutrients are released at a constant, regular and controlled rate during the longevity. Effective and efficient!	Once empty, the coating eventually breaks down.

Osmocote fertilisers are available in five different longevities: 3-4, 5-6, 8-9, 12-14 and 16-18 months. So there is an Osmocote for every situation and crop type. The colour coding on the packaging indicates the longevity. Osmocote Exact and Osmocote Exact DCT products also contain colour tracers for easy recognition. This ensures you always add the fertiliser with the correct longevity to your substrate!

The fertiliser ingredients and the thickness of the coating determine the longevity. The longevities in turn apply to an average temperature of 21°C. Higher temperatures accelerate the nutrient release, while lower temperatures slow it down.
 

Other factors such as salt levels, pH of the substrate, microbial activity, water quality and rainfall do not influence the nutrient release, making Osmocote the most reliable coated fertiliser.
