What two types of aglime are most commonly used in Pennsylvania?

The two types of aglime that are most commonly used in Pennsylvania are calcitic and dolomitic limestone. Calcitic limestone primarily consists of calcium carbonate, which is beneficial for raising soil pH and providing calcium, an essential nutrient for plant growth. Dolomitic limestone contains both calcium carbonate and magnesium carbonate, making it an excellent choice for soils that are deficient in magnesium. Both forms of limestone help improve soil structure, increase nutrient availability, and enhance overall soil health, which are crucial for successful agricultural practices in the region.

Other options refer to lime products or forms that don't align with common agricultural practices in Pennsylvania. Baked and slaked lime, quick and hydrated lime, and granular and powdered lime involve different chemical processes or forms that aren't primarily used for routine soil amendment in agricultural settings. Focusing on calcitic and dolomitic limestone highlights the preferred materials specifically tailored for addressing soil acidity in Pennsylvania's agricultural landscape.
