Pre-planting Vegetation Contol
Competitive vegetation can be controlled chemically, mechanically, and manually. Chemical vegetation control in forest is limited or restricted in many regions. Vegetation management by non-chemical means is most critical and effective during site preparation as well as after crop establishment (Ehrentraut and Branter 1990). Mechanical site preparation often results in improved seedling survival and growth, but only intensive methods with much soil disturbance are an effective tool for controlling competing vegetation (Löf et al. 2012). Mechanical and chemical site preparation combined provides the best results. After five years of weed control treatment, site preparation by plowing and harrowing did not result in increased growth of Quercus macrocarpa Michx., but growth was superior when this mechanical site preparation was combined with a simazine herbicide application (Cogliastro et al. 1997).
