The easiest home applications are limestone and wood ashes.

Limestone is primarily used in large agricultural applications.

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.

Gardening is something I have taken up in the last few years, and (finally) I can see the appeal. There is an old Chinese saying which goes to the effect......:

#"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."#
