IG-MKP (P | K)
Mono-potassium phosphate
IG-MKP is a highly efficient source of phosphorus and potassium for plants. Suitable for drip irrigation and foliar applications, IG-MKP is recommended for use early in the growing season when phosphorus availability is critical for root system establishment. IG-MKP can be mixed with other fertilizers to meet plant nutrient needs throughout the crop cycle. It is ideal for producing blends and liquid fertilizers and should not be combined with fertilizers containing calcium and magnesium.

Recommended dosages and application stages
Fertigation
It is recommended to use IG-MKP as a source of phosphorus and potassium, with nitrogen levels kept at a low level. Featuring moderate acidity, MKP is not corrosive to fertilizer pumps or irrigation equipment.
Quantitative fertigation
Each kilogram of IG-MKP in the tank provides 520 grams of P₂O₅ (equivalent to 230 grams of P) and 340 grams of K₂O (equivalent to 280 grams of K).
Foliar Nutrition
Foliar application of IG-MKP is an optional supplement to soil fertilization at growth stages when high levels of phosphorus and potassium are required. An early-season foliar application with IG-MKP promotes the establishment of a healthy root system.
Field crops and vegetables
For most crops, it is recommended to apply a spray concentration of 0.3% on young leaves. On mature leaves and more tolerant crops, the spray concentration may be increased up to 0.5%. On young leaves, a spray concentration of 0.5% IG-MKP is recommended in most crops. On mature leaves and more tolerant crops, a higher concentration (0.5% or more) may be applied.
Fruit trees
| Crop | Conc. | Timing |
| Citrus | 0.2-0.5% | 2-3 successive monthly sprays at early fruit development, starting 1 month after fruit-set |
| Stone fruits | 0.3-0.5% | 2-4 applications from fruit-set to fruit coloring |
| Banana | 0.5-1% | 2-6 applications, along with pesticides |
| Table grapes | 0.5-1.0% | 1 application during fruit-set, 1 application during ripening |
| Wine grapes | 1.0% | 1 application during fruit-set, 1 application during ripening |
| 1.0% | Every 2 weeks, starting when twigs are 10-14 cm long, alternated with a proper fungicide | |
| Olives | 1.0-2.0% |
