Free Lime in solil (calcareous soil)

Asked June 21, 2013, 3:25 PM EDT

What is the best, quickest, and most economical way to lower the pH of soils containing free lime? In addition, the well water we use to water our plants is very hard (contains a lot of calcium carbonate). So we have two strikes against us, soil which contains a high amount of free lime, and hard water that contributes to the problem by depositing dissolved calcium into the raised beds.

Hi,

There is no long-term and economic way to permanently lower or extreme buffered pH soils and water in this part of the state. They key here is to work with the soils and water that we we have, through building the soils with organic material via enriched compost over time and or green manure crops. Also, growing specific crops with a good nutrient program and irrigating with drip irrigation. The use of Iron and or sulfur products is not practical.

Good luck!
