Researches on the Protection of Vineyards and Orchards Against Spring Frosts Using Heat and Smoke and Using the Resulting Ash as Soil Amendment

Abstract

Orchards and vineyards can be exposed to climatic phenomena with unfavorable effects on tree growth and fruiting, such as: winter frosts, frosts and late spring frosts, hail, icing, etc. Smoke and heat are a valuable ally of fruit and vine growers, often intervening in preventing and limiting the negative effects of frosts and frosts on fruit trees and vines during the periods of budding, flowering and fruit binding. The accident is due to the freezing of water in the cellular structure of the vegetative organs (flower buds, buds, flowers, leaves). The paper presents a method of the protection for orchards and vineyards against hoar and late frosts as well as the possibility to use the resulting ash as soil amendment.
