Abstract

The rapid urbanization occurring in arid environments like the Intermountain West region of the U.S. significantly alters soil conditions. Construction of roads, buildings, and other infrastructure leads to the disturbance of soil structure, nutrient depletion, and reduced fertility. This research addresses the need for sustainable soil management practices that may restore soil health post-construction. In this study, the effectiveness of various soil amendments and application methods on specific soil parameters and turfgrass establishment in construction-disturbed soils was evaluated. The study highlights the critical role of soil amendments, particularly municipal solid waste (MSW) compost, in improving soil quality and plant growth. Additionally, the cost of various turfgrass establishment methods in construction-disturbed soils was evaluated. Results indicate that surface application of soil amendments facilitates nutrient access for young plants, without adversely affecting growth due to increased salinity. The economic analysis underscores that compost alone, particularly inexpensive MSW compost, is a cost-effective, sustainable option for soil restoration in urban settings. This research offers practical implications for homeowners, landscapers, and urban planners for landscape establishment in construction-disturbed, urban soils.
