How to Use

SEER Rockdust is added as a TOP DRESSING for growing medium, ie soil or compost and as a COMPOST ACTIVATOR for composting systems. As a TOP DRESSING, it has been found to benefit all types and pH of soil and promotes plant growth and vigour. It can be applied at any time of year and at any stage of plant growth.  The only exception to this is when the ground is frozen and the SEER Rockdust cannot get into the soil.  Simply sprinkle SEER Rockdust evenly onto soil from the edge of a spade or trowel then rake in, or let worms and weather do this for you.

MINIMUM ANNUAL DOSE

Apply 0.5kg per square metre, or in gardener’s terms “a handful a yard”. One 20kg bag will cover up to 40 square metres. This annual dose has also been seen to benefit lawns.

OPTIMUM ANNUAL DOSE

Apply 2kg per square metre in first year for an initial boost then apply 0.5kg per square metre in subsequent years.

MAXIMUM DOSE: As used at the SEER Centre

Apply 5kg per square metre. One 20kg bag covers 4 square metres and achieves an initial boost and the longer-lasting beneficial effect for up to 5 years or more, depending on soil conditions and type of crops grown. Apply again when soil fertility decreases.

APPLICATION to POTTED PLANTS

Sprinkle 3mm SEER Rockdust onto soil surface. No need to mix, just water your plants as normal OR mix with potting compost prior to sowing or planting. Mix ratio, by volume, of 1 part Rockdust to  4 parts compost (as used at the SEER Centre) or up to 20 parts compost (depending on the plant’s nutrient requirements i.e. light or heavy feeder).

FOR LARGE AREAS

SEER Rockdust can be applied to fields, whether grass land or cultivated, using a LIME SPREADER.   FERTILISER SPINNERS can also be used but care has to be taken to prevent the SEER Rockdust sticking to the sides of the spinner.  SALT SPREADERS with a HEAVY DUTY AGITATOR are also ideal.  The minimim dose of 0.5kg per square meter is equivalent to 2 tonnes to the acre. The optimum dose is equivalent to 8 tonnes to the acre and the maximum does is 20 tonnes to the acre. The maximum dose will be too much for grassland.

BINN AGRI

COMPOST ACTIVATOR and ACCELERATOR

As a COMPOST ACTIVATOR simply sprinkle 3 – 5mm of SEER Rockdust onto each 5 inch / 13cm layer of green waste as you add it.

MIXING WITH OTHER PLANT FOODS

SEER Rockdust has been shown to work well with soil conditioners, animal manures and plant foods.  Whilst lime can still be used to raise the pH of acid soils, we do not recommend adding it at the same time as SEER Rockdust as this reduces the effectiveness of both materials.  Leave at least two weeks between both applications.
