MKP (0-52-34) is the kind of fertilizer that contains the highest amount of main elements among the fertilizers completely dissolved in water.
The formula is KH2PO4. Due to the absence of nitrogen, it is highly suitable for intensive agricultural applications requiring intensive fertilizer use. MKP fertilizer is the most suitable source of potassium and phosphorus for plants, especially during periods where nitrogen is avoided. In other periods, it is a preferred type of fertilizer in that it provides free application of the desired nitrogen form (such as ammonium, nitrate or urea nitrogen).
