  • Phosphorus distribution in untreated and composted solid fractions from slurry separation

    Received for publication May 7, 2009. The distribution of phosphorus (P) (water-soluble inorganic P [Pi], acid-soluble Pi, and residual P) was determined in 40 samples of solids from solid–liquid separated slurry. These were collected from separation plants using different technologies, separating by simple mechanical means, by flocculation as pre-treatment before mechanical separation or by ...

  • Effect of compost-, sand-, or gypsum-amended waste foundry sands on turfgrass yield and nutrient content

    Received for publication July 19, 2008. To prevent the 7 to 11 million metric tons of waste foundry sand (WFS) produced annually in the USA from entering landfills, current research is focused on the reuse of WFSs as soil amendments. The effects of different WFS-containing amendments on turfgrass growth and nutrient content were tested by planting perennial ryegrass (Lolium perenne L.) and tall ...

  • Effects of peat moss substitution with arboretum and greenhouse waste compost for use in container media

    Plugs of impatiens (Impatiens walleriana Hook.f.), salvia (Salvia splendens Sellow ex Roem. & Schult.), and vinca (Catharanthus roseus (L.) G. Don) were transplanted into containers filled with commercial Sphagnum peat moss plus perlite medium (Sunshine Mix #1) or arboretum and greenhouse waste compost (CT), Sphagnum peat moss (PS), and perlite (PE) medium at percentages of (by vol.) 50:50 ...
