    by Simon Leake on February 17, 2020 at 5:00 am

    A survey of commercial and industrial (C&I) waste in NSW in 2008 found that a lot of recyclable material still goes to waste. This represents both a loss of usable materials (which are cheaper than new) and plenty of opportunities for entrepreneurs to make money by diverting these materials from landfill.

  • Six Reasons Why You Should Have A Plant Tissue Test Done
    by christopher@sesl.com.au (Christopher Galloway) on February 12, 2020 at 11:00 pm

    The nutrient status of a plant (and therefore its health and productivity) is ultimately determined by what it can pull out of the soil. The only way to determine how much the plant has actually taken up is by testing some of the plant tissues. Tissue analysis is a powerful tool for assessing the mineral nutrition of plants and, thus, their likely response to fertiliser. After all, too little […]

  • Soil Carbon Sequestration
    by Simon Leake on February 12, 2020 at 5:00 am

    Soil carbon – the carbon (C) present in its various forms in the soil – offers a potential means of mitigating the effects of industrial CO2 release on climate change. Increasing the C content of soil is good agronomic management, as soil organic carbon retains and buffers cations and other nutrients, holds soil moisture, encourages beneficial soil organisms and reduces soil erosion. […]

Lead contamination  Residents in any place where lead-based paints were used – in effect everywhere up until the 1970s – need to be careful of lead contamination in soil and dust. The problem is greater in older suburbs and towns (where lead-based paint has been used for up to 200 years), in inner city suburbs (where […]
