INTRODUCTION The world around us is changing. Change has always been a part of this planet, but recently the rate at which change occurs has been accelerating. Extreme weather phenomena, such as tsunamis, earthquakes, heat waves, cold fronts and floods are becoming more and more common. The natural and agricultural environment is highly affected by climate change. The leafing out, blooming, flowering, ripening of fruits, water balance and so on are all very susceptible to stress and severe damage as a result of the extreme weather. One of these extreme weather events is the drop of temperatures...

FROST PROTECTION BY SPRINKLER There are different ways to use sprinklers for frost protection, taking many factors into account. However, the same thermodynamic principles apply to all methods of irrigation: A minimum application rate of 3.0 mm/h is required. This is enough to provide protection at temperatures as low as -3˚C. Another 0.5 mm/h is required for every additional degree, i.e. if the temperature is -4.0˚C, the minimum application rate will be 3.5 mm/h (35 m3/ha/hour). METHODS OF WATER APPLICATION 1. Overhead Full Cover 233B Overhead sprinkler irrigation is a very common practice in...

2. Targeted Micro Sprinklers 2005 2002 First stage swivel Young Tree Targeted micro sprinklers spray the water directly onto the plants, with smaller amounts of water falling between plant rows. Usually a single micro-sprinkler is positioned above a single tree. A big advantage of using targeted sprinklers is that they commonly have much lower flow rates compared to conventional sprinklers. In other cases, like some of the fruit wall crops, an over lapping spacing between the microsprinklers is applied and a continues wetting zone is achieved along the relatively narrow row of trees. Giving perfect...

3. Strip Method - The latest, most adaptive frost protection solution is strip FRONT VIEW

Flipper • Recommended working pressure: 2.0-3.0 bar • Flow rate: 25-45 l/h • Filtration requirements: 130 microns (120 mesh) Our approach: In many cases, especially in apple orchards, there is a 3-meter gap between the rows of trees, and the rows themselves are very narrow, creating a “fruit wall” configuration. Other crops, such as berries, grapevines, or vines in general, are also grown in narrow rows. If we could irrigate only the row itself, without applying water to the spaces between rows, we would be able to save huge amounts of water, making it possible to protect a much larger area at...
