RCF AGRICULTURAL LIME 

Limestones are rock deposits of either primary or secondary origin. They consist essentially of Calcium Carbonate or of a mixture of the carbonates of calcium and magnesium. When 10 to 20 percent of magnesium carbonate is present the rock is referred to as “dolomite” or “Magnesium Limestone”. If the quality of magnesium carbonate is above 20 percent the rock is designated “high magnesium” limestone and if the amount approaches 45 percent the rock is then virtually a pure dolomite and is then regarded as a distinct mineral composed of calcium and magnesium carbonates. Limestones therefore vary considerably in composition and this affects the uses to which they can be put. In addition to the calcium and magnesium carbonates, impurities are often present these being – Clay, Silica, Iron, Sulphur and Manganese.

WHY RCF LIME?

The main purpose of lime and calcium carbonate is to bring the soil into a FIT STATE for beneficial bacteria to convert the organic matter in the soil into plant foods and to prevent the growth of harmful fungi.

CaCO₃ ………………..96.37%

SiO₂ ……………………….1.10%

MgCO₃ …………………1.10%

Fe₂O₃ …………………..1.75%

AL₂O₃ ………………….0.25%

LOI ………………………42.40%

Sedimentary rock consisting largely of calcium carbonate and containing not more than 15% of magnesium expressed as MgO and of which 100% will pass through a sieve of 5mm, not less than 95% will pass through a sieve of 3.335mm and not less than 40% will pass through a 150micron sieve.

Agriculture & Horticulture

RCF Agric Lime’s most important function is to adjust the soil to the hydrogen-ion concentration , or pH, which constitutes the best environment for the soil bacteria which convert otherwise unavailable nitrogen into a form ready assimilable by the plant.

It aids the decomposition of waste vegetable matter, and by reducing acidity, it retards or even prevents the development of harmful organisms which thrive in acid soils, such as the type which promote ‘club root’ in the cabbage family.

RCF Agric Lime improves the texture of the soil and renders it more workable.

RCF Agric Lime deficiency will result in low yields from crops sensitive to it, such as sugar beet, barley, turnips, sprouts, cabbage, banes and similar market-garden crops.

RCF Agric Lime is strongly alkaline and has a neutralizing value of 98.
