Mowing, Herbicide Spraying and Litter Pickup Cost Comparisons

摘要

The study evaluates the practices and costs of mowing, litter pickup, and herbicide spraying maintenance functions. Data are collected to determine the extent of and reason for changes in mowing and vegetation management costs through time series and cross-sectional data analyses. Cost comparisons are made to determine the cost-effectiveness of contract mowing and litter pickup. Overhead costs are also estimated for in-house mowing, contracting mowing, in-house litter pickup, contract litter pickup, and in-house herbicide spraying functions. The herbicide overspraying program to control Johnson grass and other pest plants is evaluated to determine its cost-effectiveness in reducing mechanical mowing and releasing Bermuda grass and various native grasses. A survey of maintenance personnel in 12 districts reveals the expected effects of implementing different vegetation control strategies in the state.
