Agricultural Lime is a vital yet still often under-appreciated aspect in good soil husbandry. We have been supplying agricultural lime to farmers for 40 years and offer a cost effective service.
With rising pressures on farm expenditure Agricultural liming is often by-passed. Acidity can affect crop performance dramatically. We advise soil testing to be carried out every one to two years to determine the Agricultural lime requirements. We offer a full soil testing service, where we can then determine how much you require. We produce our own Agriculturallime in our Quarry and deliver it with our 32 Ton trucks and we spread it with our own LPG trailed lime spreaders.
When the term is encountered in an agricultural context, it usually refers to agricultural lime, which is crushed limestone (chalk), not a product of a lime kiln. Otherwise it most commonly means slaked lime, as the more dangerous form is usually described more specifically as quicklime or burnt lime.
Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate. Additional chemicals vary depending on the mineral source and may include calcium oxide, magnesium oxide and magnesium carbonate. Unlike the types of lime called quicklime (calcium oxide) and slaked lime (calcium hydroxide), powdered limestone does not require lime burning in a lime kiln; it only requires milling.
The effects of agricultural lime on soil are:
- it increases the pH of acidic soil (the lower the pH the more acidic the soil); in other words, soil acidity is reduced and alkalinity increased
- it provides a source of calcium and magnesium for plants
- it permits improved water penetration for acidic soils
- it improves the uptake of major plant nutrients (nitrogen, phosphorus, and potassium) of plants growing on acid soils.
Lack of Lime, with a resulting increase in acidity, is a major problem for agricultural land. It occurs through acid rain, natural leaching, application of ammonium-rich fertilisers. We can guide you and determine how much agricultrual lime is needed and arrange a skilled operator to apply the agricultrual lime using up to date machinery.
pH value and Agricultural Lime Requirements
We offer a service to provide you with an accurate pH report. We understand the need for accurate and objective reporting. The degree of soil acidity or alkalinity is measured by what is known as a pH scale. A figure of pH7 represents a materials relationship to the neutral position of pure water at pH 7.0 Figures below 7 indicate increasing acidity and above 7 increasing alkalinity. The optimum for general cropping is between pH 6.8 and 7.0 For permanent grassland the optimum level pH is slightly lower.
It is particularly important to adjust soil pH well in advance for sensitive crops such as oilseed rape, sugar beet, barley and peas.
We are a family run business, with the location of our chalk pit quarry at Pyecombe, near Brighton, East Sussex. We screen all our Agricultural lime to 10mm down to dust. We have two trail spreaders, which do minimal damage to the land.
