Production that understands the soil,
certified quality
Greenforce Gübre A.Ş. — a Ministry-licensed granular fertilizer manufacturer specializing in agricultural productivity and balanced plant nutrition.
Who we are
Greenforce Gübre A.Ş. is a fertilizer manufacturer based in Mersin, Türkiye. We develop granular NPK, NP and NK fertilizers enriched with micronutrients, suited to different soil types, climatic conditions and crop requirements.
We are expanding our current monthly production capacity of 4,000 tonnes, with the aim of increasing it to 8,000 tonnes. Our products are packed and marketed under the GREENTASQ brand.
Balanced nutrition. Stronger harvests.
Our production line
Seven stages from raw material to packed bag.
How is our product made?
Raw materials are carefully ground, precisely dosed and blended homogeneously. The mixture, prepared with a controlled moisture content, is formed into granules under high mechanical pressure. The pressure and the heat naturally generated during the process allow the raw materials to bond physically.
During screening, granules that are insufficiently compacted, fragile or outside specification are separated from the final product and returned to the production line.
Production built on resource efficiency
No natural gas is used for process purposes in our production. Low water consumption is prioritized, while closed grinding and controlled screening systems are designed to reduce dust emissions.
Returning off-specification granules to the production process also limits waste and raw-material losses.
Our quality commitment
What we guarantee in every production batch:

Secondary macronutrients and micronutrients
While N–P–K forms the basis of plant nutrition, sulfur, magnesium, calcium and micronutrients help the plant use nutrients more efficiently.
Secondary macronutrients
| Element | Nutrient sources used | Main function in the plant | Observed effect on the crop |
|---|---|---|---|
| SSulfur | Ammonium sulfate (NH₄)₂SO₄Kieserite MgSO₄·H₂OSOP K₂SO₄ | Involved in the formation of proteins, amino acids, enzymes and oils; supports nitrogen utilization. | High protein contentVigorous growthOil contentTaste and aromaEfficient nitrogen use |
| SO₃Sulfur equivalent | Raw materials containing sulfates | Not a separate nutrient; it is the technical expression of total sulfur as SO₃. | S × approximately 2.5 = SO₃ |
| MgOMagnesium | Kieserite MgSO₄·H₂ODolomite CaMg(CO₃)₂ | The central element of chlorophyll; it supports photosynthesis. | Dark green leavesIntense photosynthesisSugar productionBalanced maturation |
| CaOCalcium | Calcium carbonate CaCO₃Dolomite CaMg(CO₃)₂Rock phosphate | Supports the development of cell walls and young plant tissue. | Firm fruitStrong stemsEven shapeTransport resistanceLong shelf life |
Micronutrients
| Element | Nutrient sources used | Main function in the plant | Observed effect on the crop |
|---|---|---|---|

Special nutrients added according to the formulation
Every formulation is prepared according to the plant's growth stage, the soil structure and the targeted crop quality. The appropriate product and application rate must be determined based on soil analysis, the crop, the target yield, irrigation and climatic conditions.
