Garden or agricultural lime.........

The most common component of garden lime is pulverized limestone, i.e. #CaCO_3(s)#. If you are a bit of a gardener, you know that lime is added to soils to sweeten them up, i.e. to make them less acidic. Some plants and veg LOVE lime, i.e. cabbages, spinach, peas; whereas some plants grow better in more acidic soils, tomatoes, spuds. Of course, plants are living organisms, and we are talking about soil #pH# ranges of approx. #6.5-7.5#; i.e. tolerably close to neutral. I've only recently become interested in gardening, but I can finally see its appeal. There's an old Chinese proverb that goes something like this: #"If you want to be happy for a week kill your pig and eat it."# #"If you want to be happy for a month, get married."# #"If you want to be happy for the rest of your life, grow a garden."#

undefined To reduce soil acidity, substances such as lime (calcium carbonate), dolomite lime (calcium magnesium carbonate), or wood ash can be added to the soil. These materials help neutralize acidic pH levels and raise the soil's pH towards a more neutral range.
