When fertilizing potassium sulfate or potassium chloride, how long does it take for the fruit tree (citrus) to be completely absorbed and increase the sweetness?

When fertilizing potassium sulfate or potassium chloride, how long does it take for the fruit tree (citrus) to be completely absorbed and increase the sweetness?

 The potassium oxide content of potassium chloride and potassium sulfate is 60% and 50%, respectively. Potassium chloride is slightly hygroscopic, and the price of potassium sulfate is higher. However, there is no difference in the behavior of potassium ions in the soil. Generally speaking, almost all potassium in fruits is transported from the leaves. Therefore, potassium fertilizer should be applied 2-4 months before the fruit hypertrophy period. Potassium chloride needs to be applied earlier than potassium sulfate, considering that chloride ion will promote plant tissue fiber. Therefore, early application can leaching chloride ions into the groundwater to improve fruit taste.
