What are the types and properties of lime fertilizer?

Commonly used lime fertilizers include quicklime, hydrated lime (hydrated lime), limestone powder and dolomite powder.

(1) quicklime: limestone or shells are heated and burned in a kiln. Quicklime has a strong ability to neutralize soil, and it is a kind of lime fertilizer commonly used by farmers. Because it is massive, it is generally powdered by adding an appropriate amount of water when applied.

(2) hydrated lime: quicklime is mature lime by adding water. The ability to neutralize soil acidity is also very strong, easy to use, but do not come into contact with seeds, seedlings, etc., because of high temperature, strong corrosiveness, otherwise plant dwarf is easy to be injured.

(3) Limestone powder: the main component is calcium carbonate, which is directly crushed from limestone, and the ability to neutralize soil acidity is slow. It contains all kinds of impurities, not only calcium carbonate, but also magnesium carbonate and so on.

(4) Dolomite powder: the main components are magnesium carbonate and calcium carbonate, and the ability to neutralize soil acidity is also slow.
