Compost (2002) used by the STA program were positive. The pH, soluble salt content, total nitrogen, total carbon, carbon-to-nitrogen ratio, particle size, bioassay, and respirometry measurements of all samples were within the ideal and desirable ranges for

hydrocarbons are hydrophobic and coat soil particles while also increasing carbon-to-nitrogen ratios in the soil that limit plant nutrient availability ( Aislabie et al., 2004 ; Everett, 1979 ). Conventional petroleum-based hydraulic fluids leaks often result
through tipping fees paid by municipalities to farmers averaging $3.00/yard 3 ( Derr and Kluchinski, 1995 ). However, a potential concern with the use of municipal leaves as a soil-surface mulch in vegetable production is the high carbon to nitrogen ratio
