This year's spring brought severe stress to the field crops due to the changing and difficult field conditions. These conditions, although they are not extreme, which we may encounter in March, April and May, are a characteristic feature of our climate zone. So a few words about stress in plants, about preventing stress and limiting its effects.
In Poland, spring cold spells are a common phenomenon; they occur at the end of April and in early May, during the so-called "Ice Saints". A cold spell is a drop in air temperature below the freezing point of water, i.e. below 0°C. The temperature drops from -1°C to -8°C may damage flower buds, flowers, or fruit buds in fruit trees and shrubs. Late spring frosts also often cause large losses in the cultivation of winter rape, cereals and field cultivation of vegetables.
