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.

Sod Production

The objective of this experiment was to determine the suitability of a compost obtained from a commercially available solid-waste processing plant for sod production when placed over a plastic barrier. Comparisons were made between compost-grown sod with and without fertilizer and between compost-grown sod and commercially grown sod. Six weeks after seeding or sprigging, both fertilized and nonfertilized compost-grown `Argentine' bahiagrass (Paspalum notatum Flugge), `Tifway' bermudagrass (Cynodon transvaalensis × C. dactylon), and `Floratam' St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze.] had discolored leaf blade tissue and poor growth. At 6 weeks, bahiagrass leaf tissue had a low N concentration, which suggested that the compost immobilized fertilizer N. Additionally, initial high salinity of the compost (2.85 dS·m-1) may have contributed to turf discoloration and lack of vigor. However, poor growth and discoloration were temporary. At 3 and 5 months, fertilized compost-grown turfgrasses had higher quality and coverage than nonfertilized sod. At 5 months, fertilized sod had sufficient coverage for harvest, whereas for conventional field production 9 to 24 months generally is required to produce a harvestable product. Compost-grown sod pieces had similar or higher tear resistance than commercially grown sod. One and 3 weeks after transplanting on a sand soil, compost-grown sod produced higher root weight and longer roots in the underlying soil than did commercially grown sod. The solid-waste compost used in this study offers a viable alternative material for producing sod that will benefit solid-waste recycling efforts.

Aims: Availability of nutrients-rich topsoil for nursing cocoa seedlings is becoming limited and poor growth of cocoa seedlings in the nurseries has been ascribed to the use of unsuitable potting media. Experiments were conducted to investigate the suitability of compost in improving soil chemical properties and boost the growth of cocoa seedlings at the nursery. Study Design:  The experiment was laid out in a Completely Randomized Design (CRD) with four replications. Place and Duration of Study: The experiment was carried out at the main nursery of Cocoa Research Institute of Ghana, New Tafo-Akim, between September, 2014 and June 2015. Methodology: Polybags were filled with soil obtained from an old cocoa plot (K6O2) at Cocoa Research Institute of Ghana. The soil has been classified as Rhodic-Lixic Ferrasol. Three soil: compost mixtures treatments, that is, 90:10, 80:20 and 70:30% w/w were tested. A Standard foliar fertilizer and unamended soil were included as treated and untreated controls. Seedlings were raised from mixed hybrid cocoa and assessed at bi-monthly intervals for six months for growth. Pre and post treatments soil analyses were carried out using standard laboratory procedures. Results: Initial soil analyses showed that OC (1.18%), Ca (5.60 cmol kg-1), P (14.23 mg kg-1) and pH (5.63) were below the critical values required for good cocoa growth. The 70:30 soil: compost treatment produced significantly (P = .05) tallest plant (41.9 cm) with the unamended control the shortest (30.7 cm) at the end of the study. Residual pH (6.98), OC (2.30%), P (14.23 mg kg-1) and Ca (13.02 cmol kg-1) were significantly (P = .05) higher under the same treatment compared to the unamended control; pH (5.36), OC (1.04%), P (11.65 mg kg-1) and Ca (5.60 cmol kg-1). Conclusion: Less fertile soils could be improved with the addition of Municipal Solid Waste (MSW) compost for raising good quality cocoa seedlings at the nursery in Ghana.

Glomus Intraradix

SUMMARYFive potting media components mixed in various combinations and in various percentages of one with another (0, 14·3, 29, 42, 57, 71 and 100% by volume of the second component with the first) were inoculated with Glomus intraradix in six experiments. Seedlings of citrus rootstocks were grown from seed in these mixes. Sour orange in inoculated peat plus vermiculite, Astatula fine sand plus vermiculite, and peat plus Perlite® in all percentage combinations grew c. two- to threefold taller than noninoculated control plants. Up to twofold growth increases of sour orange occurred in vermiculite amended with wood shavings. The best evidence for fungus-mediated plant growth occurred in Astatula fine sand amended with 29–71% Perlite, and the roots in that combination had the highest percentage of infection. In another experiment in which Astatula fine sand was amended with up to 16% of an acid peat, ratios of inoculated rough lemon plant growth to controls decreased as the peat content in the medium increased. Top and root weight ratios of inoculated:control seedlings in the six experiments did not fit four simple linear models.

Solid Waste Landfills

The need to introduce resource-saving technologies and environmental policies at both international and regional levels, the rapid growth of the world's population in recent centuries and related processes of industrialization, urbanization, intensification of agricultural production, increasing energy demand and, consequently, increasing waste , polluting the environment further complicates the task of substantiating the location of new landfills and assessing existing ones. In Ukraine, the issue of waste management is regulated by a number of legislative acts, plans, strategies, recommendations, they contain high-quality criteria for assessing the selected site for solid waste, but none of them has clear guidelines for identifying places for potential landfills. That would meet all the above criteria. The authors consider the problem of the lack of methods for selecting sites for landfills in Ukraine in terms of decentralization and reform in the field of waste. The experience of scientists from Russia, America, Serbia, Ethiopia, Italy, China, etc. is also analyzed, their systems of site selection, features, advantages and disadvantages are clarified. In such circumstances, an important scientific and practical task is to improve methodological approaches to determining the location of landfills and the development of land management projects for the allocation of land for landfills, because currently there is no such methodology. At the same time, the methods developed by foreign scientists need to be improved and even if they are used in Ukraine, they require adaptation to local, regional and other conditions.
