Abstract

The risk of frost is a serious problem for crop production, especially in the spring season when crops are most vulnerable to sudden temperature changes. Autumn frost is a limiting factor for the yield and quality of the produced products. The frequency of frosts in years varies greatly for different agricultural areas according to their geographical location and altitude, topographic features, presence of water basins, typical movements or directions of air masses and depends on the type, condition and care of the specific agricultural crops. To view the danger of frost, the concepts of “first and last” frost have been used in practice, which denote the first and last drop in temperatures to or below 0 °C within the biological vegetation period of plants in the specific calendar year. The article reviews the global practice of providing databases on the risk of frost damage to agricultural crops.
