Per Google…
If your PH is in the 6.0-6.5 range… you may not need lime. Crushed lime would increase your PH, and add calcium, magnesium.
Lime is not the only option for increasing calcium, magnesium (and other trace minerals)… and adjusting the PH.
Bone Meal for example has a PH of around 14… and it will raise your PH too… The nutrients typically present in bonemeal include the minerals calcium , phosphorus, iron, magnesium and zinc , as well as traces of other elements.
Gypsum — basically has no affect on your soil PH… but is a good source of calcium, Sulphur and other trace elements… Minor and trace element (Na, Cl, Mg, K, Sr ) abundances in gypsum. So if your PH is Ok… needs no adjusting, adding Gypsum may benefit.
Here is one more that I use…
greenSand is a natural lime substitute. By weathering Olivine, CO2 is sequestering into silicate, bicarbonate and magnesium. It is a chemical reaction between an acid (CO2 = carbonic acid) and the alkaline mineral olivine. The bicarbonates (= lime) counteract the acidification of the soil by increasing the pH level . Greensand fertilizer is a rich source of glauconite, which is high in iron, potassium, and magnesium . These components are all important to good plant health. It also helps loosen soil, improve moisture retention, soften hard water, and increase root growth.
I learned about Gypsum while doing forest farming… Ginseng.
Ginseng thrives in a low PH soil (a PH of 4-5 is ideal), that has High amounts of Calcium.
Gypsum is a good way to increase the Calcium, without raising the PH. It also softens the soil.
