The practical pack of a complete granular fertiliser for gardeners who expect more than a basic NPK. Every granule combines nitrogen, phosphorus and a higher proportion of potassium with magnesium, sulphur, boron and zinc, helping distribute nutrition evenly across beds, vegetables, fruiting plants and lawns. Its low chloride content also makes it a considered choice for plants that are more sensitive to chloride-based fertilisers.
A balanced nitrogen and phosphorus base is combined with a higher proportion of potassium, plus magnesium, sulphur and two useful trace elements. Every nutrient in the formula is present within each granule, helping avoid uneven distribution of different nutrients through the soil.
Compound granular inorganic NPK fertiliser with Mg, S, B and Zn for direct application to soil.
Instead of distributing separate granules with different compositions, every application point receives the same combination of nutrients.
The 17% potassium level offers the balance many gardens need for flowering, fruiting and plants with higher nutrient requirements.
Apply it directly to soil with no mixing and no calculations in litres of water; a thorough watering afterwards is all that is needed.
Use it as a base dressing at the start of active growth or as a top dressing later, when the garden needs a complete NPK with extra potassium and additional nutrients.
For flowering plants, shrubs, climbers and other garden plants during active growth.
For vegetables and edible crops that need core nutrients, magnesium, sulphur and trace elements.
For citrus, olives, vines, fruit trees and fruiting shrubs.
For even granular feeding across lawns and larger garden areas.
The rates below are indicative for garden use. Start at the lower rate for young or sensitive plants and increase only when plant size and growing conditions require it.
Use approximately 30–60 g per square metre and distribute the granules evenly over the soil surface.
Use approximately 20–40 g per square metre, spreading evenly and watering thoroughly immediately afterwards.
Use approximately 50–120 g per plant according to its size and age. Spread beneath the canopy, not directly against the trunk.
Spread over lightly moist soil, work it gently into the surface where practical and water thoroughly to begin dissolving the granules.
Do not leave concentrated granules on leaves, shoots or directly against the trunk, and do not exceed the rate. This product is not intended for foliar spraying and is not a multi-month controlled-release fertiliser.
Depending on the rate, the 1 kg pack covers approximately 17–33 m² of beds or vegetable garden, or approximately 25–50 m² of lawn per application.
Calculation basis: 1,000 g pack divided by the selected rate per square metre.
The 1 kg pack is practical for home gardens. A separate 25 kg pack is available for larger areas, orchards or regular use.
Apply directly to soil. Moisture and watering help the granules release their nutrients.
Keep the pack tightly closed in a dry place and protect it from moisture. Store away from children and pets, and wash your hands after use.
The main instructions remain simple, while the nutrient forms and percentages are listed here in full.
Do you use the same formula regularly or cover a large area? The 25 kg pack provides the same Nitrophoska® Special in a more economical size.

Straightforward answers on rates, watering, coverage and correct garden use.
Every granule contains the same complete 12-12-17 formula together with magnesium, sulphur, boron and zinc. This helps distribute nutrients more evenly through the soil, while the higher potassium ratio is particularly useful for gardens with flowering, vegetable and fruiting plants.
Use an indicative rate of 30–60 g per square metre. Start at the lower rate for young or more sensitive plants, distribute the granules evenly over the soil and water after application.
For lawns, use an indicative rate of 20–40 g/m². For fruit trees and shrubs, use approximately 50–120 g per plant according to size and age, spreading beneath the canopy rather than directly against the trunk.
Spread the granules evenly over lightly moist soil, away from shoots and leaves. Work them gently into the surface where practical and water thoroughly so moisture can begin releasing the nutrients.
No. It is a compound granular fertiliser whose nutrients become available with moisture. It does not replace a multi-month controlled-release fertiliser and should not be overapplied.
