Gemstones associated with metamorphic rock include beryl, jade, lapis lazuli, turquoise, spinel, ruby, sapphire and zircon. Rocks and minerals are in a constant state of change, which is referred to as the rock cycle. Igneous rock can change into sedimentary or metamorphic rock.
Lime is a soil amendment made by grinding limestone, a naturally occurring type of rock that is very high in calcium. Two types of lime are commonly used in lawns and gardens, agricultural lime and dolomitic lime. Agricultural lime, also sold as garden lime, is made from calcium carbonate.
Use your soilâs pH test to determine how much lime is necessary. Wait for the right day. As we said before, fall is the best time to apply lime. If you lime your lawn before the first frost of the year, the freezing/thawing pattern of winter will help the lime seep into the soil. Donât apply lime when your soil is very wet and avoid windy days, especially if your lime is in powder form.
