Abstract/Contents:"Compost amendment of soils degraded by urban development is seen as a way to improve soil and landscape quality, reduce runoff, and create a high-value market for locally produced compost. This review evaluates literature on organic soil amendments used in agriculture and horticulture, and extends results to disturbed soils in urban landscapes. Research on agricultural use of organic amendments consistently shows soil bulk density and penetration resistance decreasing with increasing amendment rate, and aggregate stability, porosity, and infiltration rate increasing with amendment rate. The effect of organic amendments on plant available water is less clear. Although organic amendments increase soil water holding capacity, much of the increase may not be available to plants. The nutrient benefits of compost amendments are often overlooked. Composts with C:N ratio of 20:1 or less can provide significant amounts of nitrogen and other nutrients, improving the establishment of turf and landscape plants, and reducing the amount of supplemental nutrients needed. Materials with high C:N ratio immobilize N, which can retard plant establishment. Results suggest that compost amendment rates of about one-third by volume should be suitable for establishing landscape beds in humid, temperate environments in soils degraded by development. Rates of 15 to 25% by volume are suggested for lawn establishment."
