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
(carbon-to-nitrogen ratio is 500:1 for PTS and 50:1 for PB) because differences in dry weight are not present when fertilizer was applied with one exception—vinca at 1 lb/1000 ft 2 in 2006. However, N immobilization would not explain why marigold growth

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
landscape establishment and could cause root circling, leading to restricted water and nutrient movement and ability to adequately anchor. A high carbon-to-nitrogen ratio (138:1) of peat containers (S. Nambuthiri, unpublished data) may have limited their
