ICL Osmocote Pro 3–4M 19-9-10 + 2MgO + TE - 25kg

Verified nutrient analysis

The current ICL product information states 19% total nitrogen, 9% P₂O₅, 10% K₂O and 2% MgO, together with trace elements. This page uses the current 19-9-10 analysis rather than relying on older or market-specific product information.

For shorter crop cycles

ICL describes Osmocote Pro 3–4M as a controlled-release fertiliser for short crop cycles and rapidly growing plant material. Its 3–4 month longevity can make it appropriate where the production period is relatively short and a longer-duration fertiliser would extend beyond the intended crop cycle.

Using controlled-release fertiliser

Choose the product longevity and application rate according to crop species, container size, production period, growing-medium fertility, irrigation regime and supplementary feeding programme. Controlled-release fertiliser should be distributed consistently through or applied to the growing medium using a method appropriate to the crop and production system.

Avoid damaging coated granules during mechanical handling or application, as damage to the coating can alter nutrient release.

Temperature & nutrient release

Controlled-release fertiliser performance is influenced by growing conditions, particularly temperature. Crop nutrient demand also changes with growth rate, irrigation and season, so monitor crop response rather than assuming the stated longevity alone guarantees the correct nutrition programme.

Integrating with irrigation & water-soluble feeding

Account for nutrients already supplied by irrigation water, growing media and any supplementary fertiliser. Where water-soluble feeds are also used, adjust the overall programme to avoid unnecessary nutrient loading.

Storage & handling

Store fertiliser dry and protected from contamination and physical damage. Follow the current ICL product information and safety data sheet for handling, application and storage requirements.
