Resumo(s)
This book describes the physics and biology of frost occurrence and damage, passive and active protection methods and how to access the cost-effectiveness of active protection techniques. Night-time energy balanceis used to demonstrate how protection methods are used to reduce the likelihood of frost damage.Simple methods and programs are provided to help predict temperature trends and to help determine the timing for active methods. Plant physiology related to freeze damage and critical damage temperatures for a wide range of crops and ornamentals are presented. Finally, an economic analysis program with examples is included to assist users to evaluate cost-effectiveness of various active methods. Although the book contains considerable technical information, it was specifically written for growers rather than scientists as a practical guide for frost protection
