The Gronamic range
Combines organic and mineral nutrients with Organo-mineral nutrients. A balanced and reliable nutrient supply can be achieved by using them all year round.
Key benefits:
-Multiple sources of nitrogen for gradual nutrient release
-Complex formulations contain Polyhalite (source of K, Ca, Mg, S)
-Long potency
-Low C:N ratio, which promotes faster nutrient uptake
Composition and effect:
Organic matter content of products ranges from 39-100%
Nitrogen comes from multiple sources: Urea, ammonium, organic nitrogen
C:N ratio in all products is optimized for mineralization
Order of N sources:
- Ammonium → Urea → Organic (mineralizing) N
Gronamic products contain a variety of carefully selected N sources → for phased nutrient uptake
As the Gronamic granules decompose in the lawn:
- Ammonium first,
- Then urea,
- Finally, mineralizing organic nitrogen supplies the plant.
Result: a sustained supply of nitrogen from a single product.
The C:N ratio of Gronamic products allows the mineralisation of organic nutrients without binding (immobilisation).
The C:N ratio determines whether:
- organic nutrients are readily converted into an absorbable form,
- mineralization (release) or immobilization (binding).
General rule:
- C:N < 20:1 → mineralisation occurs (all Gronamic products fall under this rule)
- C:N > 30:1 → immobilisation occurs
Recommendation for use:
Package: 25 kg
Dosage: 25-40 g/m²
Duration of action: 6-12 weeks
Granule size:2-4 mm
Characteristics of ICL Gronamic Sport High K:
Gronamic High K provides a sustained supply of nutrients to the turf throughout the growing season and high potassium levels in the autumn. The provision of all essential macronutrients results in healthy plants, excellent turf colour and good wear resistance. The balance of mineral and organic components provides the benefits of both nutrient supply methods. Provides carbon and a balanced C:N ratio in the soil/root zone.
Guaranteed composition:
N: 7%
P: 0%
K: 20%
Organic matter content: 49%
Contains polyhalite which provides Ca, Mg and K.
Benefits:
- High potassium content to support the plant during periods of stress
- Low nitrogen levels for slower growing periods of the year
- Polyhalite mineral to provide Mg and K for healthy growth
Dosage:
Recommended dose: 20-40 g/m2
Directions for use:
1 Apply to dry foliage
2 If there is no rainfall within 1-2 days after application, water
3 Irrigation or rainfall will promote particle degradation and reduce the risk on short-cropped surfaces
4 Avoid application during periods of frost or drought
5 Do not mow or rake the lawn for 2 days after application to ensure proper degradation of the product
6 The product contains iron, so if it is spilled on paving, concrete or decorative surfaces, sweep it off immediately as it may cause discolouration
