We evaluated the effect of fertilization treatments in combination with clippings disposal on perennial ryegrass (Lolium perenne L.) in two adjacent locations. Clippings left on turf during mowing decreased dollar spot (Sclerotinia homoeocarpa F.T. Bennett) in both locations during three summers compared with clippings removed in mower baskets. However, brown patch (Rhizoctonia solani Kuhn) increased during July and Aug. 1995 when clippings were left on turf. Dollar spot was more severe with N (kg·ha–1·year–1) at 120 compared to 240; brown patch was more severe at 240. While clippings disposal had significant effects on disease incidence, implementation may not be practical because of the contrary responses of the observed diseases to this management approach.
( Cabral, 2005 ). Pruning wood is currently burned as an economic means of disposal. However, the New Mexico Environment Department and the U.S. Environmental Protection Agency are concerned with this practice and may restrain, prohibit, or otherwise
14.7 × 10 5 tons in 2017 ( Gao et al., 2019 ). Although PE mulch has many advantages, there are also growing disadvantages, largely due to disposal challenges and potential soil and water contamination. Removal from the field is labor intensive, and
to the nursery. The shrub would be transported to the landscape with a light truck and trailer as part of a 50-plant load traveling 32 km. After 50 years of useful life, removal and disposal of the shrub after a 50-year useful life would require 0.5 h
, positive impact on atmospheric GHG. The life cycle GWP of the described redbud tree, including GHG emissions during production, transport, transplanting, take-down, and disposal, would be a negative 63 kg CO 2 e ( Ingram et al., 2012 ). These data can be
economic means of disposal. However, pruned wood is increasingly chipped and incorporated into the soil as an environmentally viable method of handling the waste. Although more expensive than burning, chipping and soil incorporation avoid burning controls
the development of water use restrictions and decreases in permitted water use for agriculture. Increased use of reclaimed water for agricultural irrigation would not only reduce the wastewater disposal problem for urban areas, but could also reduce
). The conversion of squid waste (squid byproducts) into organic fertilizer may present a solution to problems associated with high disposal costs for squid processors. The economic burden of squid byproduct disposal, and the high N content associated
The availability of organic components of potting media is limited due to supply and shipping costs. Disposal of solid waste has also become a serious problem for many municipalities. The utilization of solid waste compost in agricultural production promises to be a solution for both concerns. The objective of this experiment was to determine the efficacy of sol id waste compost from Miami, Dade County, Florida as a propagation medium for vegetative reproduction of ornamental and landscape plants.
Cuttings of Podocarpus macrophylla, Chrysobalanus icaro, and Impatiens spp. 1-13 cm long, treated with .2% NAA ppm IBA were rooted in media composed of sphagnum peatmoss: perlite (1:1) or Agrisoil (TM) solid waste compost: perlite (1:). Cutting rooted well in both media. Data included number of roots and root weight.
.8% on a dry weight basis ( Mitchell et al., 1995 ). Land application was the predominant disposal method for PL in the past. However, as a result of increased environmental awareness, PL is now under strict new state and federal regulations concerning
