Topsoil Investigation Screen

Topsoil Investigation Screen

Is your topsoil up to scratch? Many of us spend thousands of pounds on our gardens, creating an idylic space to sit back in and relax. But much of that effort could be wasted if the topsoil we are working with is not up to scratch. Sub-optimal fertility levels and in some cases where a handful of unscrupoulous suppliers pass off poorly sourced “dirt” as topsoil, even dangerously contamination materials can be lurking beneath our feet. “Why chance it? Test it!” is a motto Safe Soil UK lives by.

 

To that end, we devised the Topsoil Investigation Screen, which looks at fertility levels, including phosphorus, magnesium and potassium, as well as checking for contaminant levels to ensure we are not compromising our well-being and indeed the health of our loved ones. In addition to asbestos and various hydrocarbons, we also take in heavy metals including lead, mercury and cadmium among other potentially dangerous elements.

 

Our TI Screen can set your mind at ease that the soil in your garden or growing space is fertile and safe, adhering to British Standards Institute (BSI) topsoil parameters as set out in BS3883:2015.

  • SHIPPING INFO:

    We will send you a testing kit that includes a soil sample bag and amber jars (these needs to be filled right to the top because some of the elements we are testing for can interact with air) as well as instructions on how to take samples from your garden or allotment. When you're done, place the two-thirds full sample bag and full jars back in the box that will have a pre-paid postage label already affixed, seal it and pop the package into a Royal Mail post box or drop it off at a local post office.
