This lime is mostly used in horticultural enterprises and is not usually applied to pastures; Slaked lime (also called hydrated lime or builder’s lime) is calcium hydroxide (Ca(OH)2) and has a higher neutralising value than agricultural lime but is more expensive and not usually applied to pastures Are both materials essentially able to accomplish the same objectives? Due to the fact that limestone dissolves very slowly, it’s only able to neutralize soil acidity in the earth directly surrounding each particle of lime. The material is worked into the soil, and reacts when introduced to water. Very fine lime has 98-100 per cent fines (as they are called) and this is the grade you are recommended to buy (Refer table 1). Dolomite Agricultural lime has been in use as far back as ancient Roman times, and has proven time and again to be an extremely effective and efficient method for achieving balance in soil pH.

Noticeable results can be detected within a few weeks of the agricultural lime’s introduction. However, you must also take into account other Here in the northeast, we’re not unfamiliar with periods of heavy rain – especially throughout the summer months.

While it’s true that both agricultural limestone and hydrated lime both have their merits, it’s important that you carefully calculate your needs and preferences before making a final decision. However, because lime quality can vary due to changes in the area or depth mined or the degree of crushing, the analytical results of future lime samples from the same company may vary. The liquid lime can then be sprayed upon the surface of the soil. For the purposes of comparison calcium carbonate is given a neutralising value of 100; ideally NV should be over 95, Lime manufactures have to specify the percentage of particles finer than 0.25 mm (a quarter of a millimetre in diameter). Hydrated, or liquid, lime is a mix of 50% agricultural lime and 50% water.
