Protection systems against late spring frosts in permanent crops

The appearance of late spring frosts due to climate changes causes’ great damage to orchard – viticulture production. The main aim of the paper was to study and process all methods of protecting permanent plantations from late spring frosts. The causes and occurrence of frost, as well as measures and methods of suppressing negative effects are explained. Protection methods are divided into three most important: active, passive and chemical measures. The methods that are in the domain of agricultural engineering are explained in detail, because researches show that they are the most effective: using a sprinkler by slow raining ; direct heating (stationary furnaces and mobile heat generators), fans for air mixing. Among the other possibilities, the methods with smoking and covering of permanent crops still show some effectiveness. Domain of protection of permanent crops regarding late spring frost, due to climate change, will become more pronounced, and agricultural engineering must keep up with the challenges of modern production and give an answer to all challenges
