SuperSlag Basic

Steel works slag varies slightly, but typically contains the following elements. Also recorded are commonly found maximum contents.

 These samples were analysed by various laboratories from steel works slag from South Wales.

Steel Works Slag

Steel works slag is a by-product of the basic oxygen steel making process used by Corus at their Port Talbot, Scunthorpe and Teeside works.

Like the old basic slag our grade of steel works slag called Super Slag Basic is principally a lime based material which has absorbed the oxides and trace elements arising from the refining of iron. Although it contains less phosphates than the old basic slag. Super Slag Basic produces a high phosphate response in the soil owing to its soil conditioning properties. Field trials and practical experiences have shown that steel works slag performs exceptionally with significant improvements in crop yield and pasture quality.

Super Slag Basic has similar neutralising properties to that of ground limestone and is applied to the land at a similar rate, appropriate to its pH level. At the maximum recommended rate of 1.5 tonnes/acre, it provides around 38 units of phosphate together with magnesium, manganese, boron and a wide range of trace elements essential for healthy crops and animal wellbeing.

On spreading, Super Slag Basic acts in four ways. It provides:-

• an effective source of phosphate

• an effective source of lime

• a source of essential trace elements

• a release mechanism for locked up phosphates.

Super Slag Basic is crushed down to a size that is agronomically effective. It is safe to handle and easy to spread and is prepared to 4 ml to dust particle size. This size gives the optimum release of nutrients whilst enabling ease of handling and spreading.
