Crop yield is ultimately dependent upon weather events. Soil moisture, soil temperature, insect damage, disease development, and weed competition are each directly influenced by the meteorological environment. Crops are directly impacted by freezing events, which may have wide area impact, and by localized events such as hail storms. The weekly monitoring of meteorological events is crucial to evaluation of crop condition and development. To the extent that events may be anticipated, production and marketing strategies may be adjusted to manage the risk associated with an agronomic system.
