Tropical storms tornadoes and strong winds

Wind induced stem and root lodging of crops is too widely occurring but understanding of the complex interaction between husbandry as a mitigating factor, weather and soil has just begun (Sterling et al. 2003). Variety choice, sowing date, seed rate, drilling depth, soil fertility and the widely used application of plant growth regulating chemicals are the best known mitigation factors in large scale cereal growing (Berry et al. 2003; Sterling et al. 2003). Wind reduction in agriculture as far as very strong winds are concerned have mainly to do with microclimate manipulation using forestry and non forest trees (e.g. Stigter et al. 1989; Stigter et al. 2002; Ruck et al. 2003; Stigter et al. 2003b).

Even mildly strong winds can be disastrous, as the wind erosion problems in northern China illustrate, but again mitigation with ground cover and plantings has the solutions (e.g. Zhao Caixia et al. 2006). On the other hand there are positive effects from wind damage of forests as well (e.g. Ruck et al. 2003). ttis also applies to the humid and sub-humid tropics (e.g. Zhao Yanxia et al. 2005).
