EC Fertilisers - Lime
Hanson can supply powdered limestone that can be used for agricultural applications like conditioning soil and the production of animal feed. We quarry agricultural limestone, which is then crushed, ground into a fine powder and applied as a soil conditioner on agricultural land.Using ground limestone on soil can:
- Increase the pH of acidic soil to reduce acidity
- Provides a source of calcium and magnesium for plants
- Allows for improved water penetration for acidic soils
- Helps the uptake of major plant nutrients
Aggregates for SUDS sub-base
Hanson can supply aggregates for the sub-base of Sustainable Urban Drainage Systems (SUDS).We have worked with the UK’s leading SUDS providers to create a range of aggregates that help reduce flood risk and improve water quality.
Hanson’s range offers blended aggregates combined to produce voids that allow the free flow of water whilst still retaining the mechanical strength of the inter-locking particles.
Hanson can offer both a 4/20 aggregate mix and a Type 3 sub-base bespoke products are available upon request.
Our aggregates meet the required specifications for SUDS systems as well as Interpave’s latest guidance.
