SCRAP produces around 0.5 tonne of worm casting per week from our worm farms. Our bulk rate includes delivery across Sydney and to the mid Blue Mountains. Rich in humic and fulvic acids, micro-organisms and worms, the casting will massively increase your soil’s productive capacity.
Not sure how much you need? Multiply the length of your garden by the width and then by a depth of around 200mm. This will give you the volume of soil. Adding a 30% mix of casting will lift the soil considerably, improving crops noticeably within a couple of weeks. The example of a 4m2 bed at 225mm deep has a volume of 0.9 cubic metres requiring up to 0.3 m3 of worm casting or around 250kg. For assistance with calculations and prices for smaller orders call us on 0400 982 516 and see our other options on this page for 4L and 10L bags.
