Yates Nutricote N16 Blue Controlled Release Fertilizer

Yates Nutricote N16 Blue 25kg: Controlled Release Fertiliser (16-4.4-8.3, Type 140)

Yates Nutricote N16 Blue is a premium controlled-release fertilizer that gives plants a steady, consistent supply of nutrients from a single application. It carries a balanced NPK analysis of 16-4.4-8.3, delivering the nitrogen, phosphorus and potassium plants need for strong root development, lush foliage and good flowering. It suits a wide range of plants, including flowers, vegetables, shrubs, ornamentals and potted plants, which makes it a practical one-product feed for the garden, containers and nursery.

The way Nutricote releases is what sets it apart from ordinary fertilizer. Each granule is coated with an advanced resin that controls how quickly nutrients are released, and that release is regulated by soil temperature. As it warms and plants are actively growing and needing more, the granules release faster, and as it cools and growth slows, release slows too. This keeps feeding broadly in step with plant demand rather than dumping everything at once, avoiding the feast-then-famine pattern of quick-release feeds.

This is the Blue (Type 140) grade, formulated to release over roughly 140 days, which typically works out to around four to six months in the garden depending on soil temperature. That controlled release means one application replaces months of repeat feeding, and because nutrients are released slowly rather than all at once, far less is lost to leaching and runoff, making it efficient, economical and cleaner than heavy repeat doses of soluble fertiliser.

How to Use

Apply at the start of the growing season or just after planting, then water well to begin the release. As a general guide:

• Garden beds and shrubs: apply evenly around the root zone at about 50 to 100 grams per square metre.

• Pots and containers: mix into the potting mix at about 5 grams per litre.

• Vegetables and flowers: spread evenly and lightly mix into the top layer of soil.

Always water in after applying, since soil moisture and warmth are what start and drive the controlled release. For exact rates on specific plants, follow the product label.

Getting the Best From It

• Apply at the start of the season. Feeding early lets the release period cover the main growing window from one application.

• Always water in. The release is driven by soil moisture and temperature, so watering after applying gets it working.

• Mix it through potting mix. For containers, blending it evenly gives consistent feeding rather than one concentrated pocket.

• Don't over-apply. It is efficient and long-lasting, so the recommended rate is enough. More is wasteful rather than better.

Frequently Asked Questions

How long does Yates Nutricote N16 Blue last?
It is the Blue (Type 140) grade, formulated to release over roughly 140 days, which usually works out to around four to six months in the garden depending on soil temperature.

What is the NPK analysis?
It has a balanced analysis of 16-4.4-8.3 (nitrogen, phosphorus, potassium), suited to a broad range of plants.

How does controlled release work?
Each granule has a resin coating that regulates nutrient release according to soil temperature. Nutrients release faster in warm, active-growth conditions and slower when it is cool, keeping feeding broadly in step with plant demand.

What is the difference between N16 Blue and N14 Magenta?
Both are Nutricote controlled-release fertilisers with slightly different NPK analyses. The N16 Blue (Type 140) is a medium-term feed lasting around four to six months, while the N14 Magenta is the long-life grade formulated to feed for up to 12 months. Choose based on how long you want one application to last.

How do I apply it?
Apply at the start of the season or after planting, spread it around the root zone or mix it through potting mix, and water well. Use around 50 to 100g per square metre for beds, or about 5g per litre of potting mix.
