DeltaCote controlled-release fertilizers

Controlled nutrition for better crop performance

DeltaCote controlled-release fertilizers are designed to provide crops with a consistent and efficient nutrient supply over a defined period. By controlling nutrient release, DeltaCote helps align nutrient availability with crop demand, supporting healthy growth, strong root development and more efficient fertilizer use across a wide range of crops and growing systems.

• Available in different longevities to match crop cycles and growing conditions
• Controlled nutrient release for more consistent crop nutrition
• Suitable for ornamentals, fruit & vegetables, arable crops and plantations
• Improved nutrient use efficiency with reduced nutrient losses
• Helps reduce leaching and unnecessary fertilizer losses
• Fewer fertilizer applications and more efficient crop management
• Supports strong root development and balanced growth
• Flexible formulations for different crops, markets and applications

CRF solutions for arable crops and field production

Conventional fertilizers can release nutrients faster than crops are able to absorb them, while nutrient demand changes continuously throughout the growing cycle.

When nutrient availability exceeds crop uptake, part of the fertilizer may be lost before the plant can use it effectively. This can reduce nutrient use efficiency, increase the risk of leaching and result in less consistent crop nutrition.

Modern crop production therefore requires more than simply supplying nutrients. The challenge is to make nutrients available in the right amount, at the right time and for the right duration.

The DeltaCote approach: control the release. Match the crop.

DeltaCote is a controlled-release fertilizer technology designed to regulate nutrient availability over a defined period. The coating around each fertilizer granule gradually controls nutrient release, helping synchronize nutrient availability with crop demand. This supports more consistent crop nutrition, improved nutrient use efficiency and reduced nutrient losses throughout the growing cycle. Whether used in ornamentals, vegetables, field crops or long-cycle plantations, DeltaCote provides growers with a more controlled approach to crop nutrition.

What is DeltaCote?

DeltaCote is our controlled-release fertilizer technology, designed to deliver the right nutrients at the right time, for higher efficiency, stronger crops and a more sustainable future. It is a complete technology platform (previously known as Ekote) combining coating technology, formulation expertise and manufacturing capabilities to develop nutrient solutions tailored to specific crops, markets and nutrient-management requirements.

We help growers, distributors and fertilizer manufacturers apply the right nutrient source, at the right rate, at the right time and in the right place, through controlled-release nutrition designed around crop demand.

From 3 to 18 months predictable release

No leaching. No scorching. More efficient crop nutrition. Depending on product design, nutrients are released predictably over 3 to 18 months.

How does DeltaCote work?

Every granule is coated with a polymer that controls the release of nutrients. Moisture enters the granule, nutrients dissolve and are released gradually through the coating membrane. The release rate is influenced by soil temperature and is always matched to the nutritional requirements of the crop.

01

Nutrients encapsulated

Macronutrients (N, P, K) and other trace elements are encapsulated in an organic polymer coating.

02

Water enters

After being applied, the granule attracts water, which passes through the coating.

03

Nutrients dissolve

The nutrients dissolve in water to form a concentrated nutrient solution inside the granule.

04

Controlled release

Depending on the product design, the formulation is released over a specified period, from 3 up to 18 months.

What controls release?

Flexible coating coverage

We offer different coating coverage levels to match your crop, nutrient program and desired balance between immediate and controlled nutrient availability.

Or a tailored solution for your specific requirements. By adjusting the proportion of coated and uncoated granules, we can develop formulations that provide both immediate nutrient availability and controlled release, around crop demand, application timing, nutrient requirements, growing conditions and target release period.

Formulation flexibility: one technology, multiple fertilizer possibilities

DeltaCote can be incorporated into different fertilizer formulations, allowing us to develop controlled-release solutions for a wide range of crops and applications.

Nitrogen fertilizers

Including coated urea for regulated nitrogen release.

NPK fertilizers

Partly coated and uncoated formulations for a balanced nutrient supply.

Specialty fertilizers

With secondary nutrients and trace elements.

Tailored solutions

Customized formulations for specific crops and markets.

Why DeltaCote: controlled nutrition designed around the crop

One technology. Multiple crop solutions.

Different crops require different nutrient ratios, release periods and fertilizer strategies. A short-cycle vegetable crop has very different nutritional requirements from a nursery plant, arable crop or perennial plantation. That is why DeltaCote combines controlled-release fertilizer technology with different formulations and release profiles, allowing crop nutrition programs to be adapted to the specific requirements of the crop and production system.

01

Ornamentals

Controlled nutrition for consistent quality

Ornamental crops require balanced nutrition throughout their production cycle to support strong roots, healthy foliage, compact growth and flowering. DeltaCote provides consistent nutrient availability for container-grown plants, bedding plants, nursery stock and other ornamental crops.

Best suited for: Potted Plants, Bedding Plants, Nursery Crops, Container Production, Flowering Ornamentals

02

Fruit & vegetables

Efficient nutrition from establishment to harvest

Fruit and vegetable crops experience changing nutrient requirements throughout establishment, vegetative growth, flowering and fruit development. DeltaCote helps maintain nutrient availability throughout these stages, supporting crop development, fruit quality and efficient fertilizer use.

Best suited for: Vegetables, Fruit Crops, Greenhouse Production, Protected Cultivation, Open-Field Production

03

Arable crops

Reliable nutrition throughout the growing season

Arable crops require efficient nutrient management across large production areas and changing growing conditions. Controlled nutrient release helps align nutrient availability with crop development, supporting strong establishment, efficient nutrient use and productive yields.

Best suited for: Maize, Wheat, Potatoes, Sugar Beet, Oilseeds, Broadacre crops

04

Plantations

Long-term nutrition for long-cycle crops

Plantation crops require reliable nutrient availability over extended growing periods. DeltaCote provides controlled nutrition designed to support root development, vegetative growth and sustained crop productivity while helping improve fertilizer-use efficiency.

Best suited for: Coffee, Tea, Fruit Trees, Tree Crops, Tropical Crops, Perennial Plantations

From fertilizer application to controlled nutrition

DeltaCote helps move crop nutrition from rapid nutrient availability toward a more controlled and crop-focused approach.

Nutrition designed around your crop

Every crop and growing system has different nutritional requirements. By combining the right nutrient formulation with the appropriate release period, DeltaCote enables fertilizer programs to be designed around the actual requirements of the crop.
