Why do vineyards and orchards use wind machines and heaters?

Wind machines provide protection by mixing the air in the lowest parts of the atmosphere to take advantage of the large amount of heat stored in the air. The fans or propellers minimize cold air stratification in the orchard and bring in warmer air from the thermal inversion.

How does a wind machine work?

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

What does the Bible say about the vineyard?

Why do they plant mustard in vineyards?

Mustard growth helps suppress nematode population (microscopic worms that can damage vines), because mustard contains high levels of biofumigants. Some vineyards have created their own varieties that are specifically bred to have high levels of Glucosinolate compounds, or are 'extra spicy,' to further deter nematodes.

How do frost fans work?

Frost Fans work by utilizing warmer/drier air from the 'inversion' layer to create air movement at the fruiting/flowering height in orchards on still cold nights—preventing damage to flowers, soft tissue and fruit. Many growers have moved away from using water sprinkling in preference for frost fans.
