Which fertilizer increases acidity of soil

If the two nitrate ions were taken up by a plant, two of the hydrogen ions would bind with hydroxide ions released from the plant, leaving one hydrogen ion contributing to soil acidity.

If the two nitrate ions leached away from the root zone, all three hydrogen ions would remain to contribute to soil acidity. If nitrate ions taken up by the plant are from potassium nitrate fertiliser, there is a liming effect because hydrogen ions are neutralised in the process.

If those nitrate ions are leached, there is no liming effect, but also no soil acidification because no hydrogen ions are contributed to the soil with the fertiliser. Causes of soil acidity.
