Effective frost protection for crops: Innovative irrigation solutions

In response to increasing spring frosts, safeguarding plants from low temperatures is vital for orchardists and growers. Overhead irrigation emerges as a top solution, effectively shielding plants from frost damage by forming an insulating layer of ice when temperatures drop below freezing. Innovative irrigation systems like NaanDanJain's 233B and Flipper sprinklers, alongside Senninger's Wobbler sprinklers, are tailored for growers seeking efficient protection against adverse weather. Renowned for their reliability and effectiveness, these solutions bolster crop health and productivity, empowering farmers worldwide to mitigate losses and enhance market competitiveness.

Frequently Asked Questions

When should I start anti-frost irrigation?

Plants should be sprinkled from the moment the temperature drops below 0°C until it grows above zero again. It is recommended to stop irrigation when the wind speed exceeds 5.0 m/s to avoid stream drift.

What are the design principles?

The minimum water requirement for protection against frost of -3°C is 3 mm/h. With larger frosts, water demand increases by 0.5 mm/h for each additional degree of frost. Example: if the temperature is -4 °C, the minimum water demand will be 3.5 mm/h.

How much water does an overhead irrigation system use?

Water consumption depends on many factors and the solution used, but to protect 1 ha of crops, one should adopt: 
  • Flipper: approx. 20 m3/h/ha 
  • 233B: approx. 35 m3/h/ha 
  • Mini Wobbler™: approx. 30-50 m3/h/ha 
  • Xcel Wobbler™: approx. 30-50 m3/h/ha

How far apart should sprinklers be placed?

Sprinkler spacing depends on many factors, such as the type of crop, terrain conditions, local climate conditions and farmer preferences. In general, however, it is recommended to space the sprinklers evenly to ensure uniform water coverage of the growing area during the overhead irrigation process. It is worth contacting our experts who can provide more detailed information and advice on the optimal placement of Flipper, 233B and Wobbler sprinklers in a specific crop situation.

Does overhead irrigation only work in fruit orchards?

This is an effective method of protecting plants against frost and can be used in various types of crops. In addition to fruit orchards (peaches, apricots, apples, pears, plums, cherries, sweet cherries, grapes...), overhead irrigation can also be used in other types of crops: vegetables, e.g. tomatoes, cucumbers, peppers, ornamental plants, e.g. roses, chrysanthemums, lilies, herb and spice plantations.

What are the costs of installing a frost protection system?

Installation costs of Flipper, 233B and Wobbler overhead irrigation systems may vary depending on the size of the growing area, type of terrain and local conditions. However, overall the costs are not high because the installation is simple and you can do it yourself. It is recommended to consult with irrigation specialists for an accurate cost estimate and advice on optimal installation.
