Most crops require more potash than sulfur. How do I get a proper fertilizer blend using K-Mag Fertilizer?
Generally, K-Mag is not used as a source for the total potash requirement. For most field crops, K-Mag will be recommended at a rate to supply most, if not all, of the magnesium and sulfur fertilizer requirements. Then, muriate of potash (KCl) would be used to provide the remaining potash needed. In high-cash-value crops – where quality is critical for marketing, chloride sensitive crops are grown, or when low salt index is required – K-Mag can be used in combination with potassium sulfate or potassium nitrate to provide the remaining potash.
