Installing the frost blanket directly on top of the recently planted row increases yield at the end of harvest.

Protection against Cold Weather and Frost

Frost blanket INVERNAVELO® is make from nonwoven polypropylene. That is use as a protection for crops during the brief but devastating frosts of fall and winter.

With a frost cover you can prevent the total loss of what you planted because of brief freezes of down to 5 degrees below zero (23° F). 

This blanket creates a thermal buffer, capturing heat store in the ground, which is a thermal mass heat by IR rays during the day. This radial value gets return to the atmosphere during the night.

INVERNAVELO® essentially traps this thermal delta creating a thermal difference of several degrees. This is enough to save the crop, having created the effect of a greenhouse.

As a frost shield

This frost blanket prevents direct contact with nighttime dew.  As the night passes, dew comes into contact with plant tissue of the vegetables and their plants. 

This moisture, as the temperature falls and drops below zero (32° F), ends up freezing and consequently the fruits and leaves do too. 

Frost blanket act as a shield and the moisture dont be in contact with the plant. When the temperature drops below zero (32° F), the frozen water remains on top of the fabric without harming the plants.

Obligating crops with the nonwoven INVERNAVELO®

Every farmer, know that getting to the market with one week’s difference to the competition, can mean unexpectedly high earnings. 

To the contrary, getting to market late sometimes obligates one to abandon the harvest or deliver it to livestock. Because harvesting costs more than what the market pays. 

Being able to create this ideal microclimate which manages to force the seed and seedling by heating the soil. Trapping the warmth in this thermal mat, permits advancing to the vegetative stage.

These types of advantages allow the grower who use INVERNAVELO® to uncover the plants when the weather is warmer. The plants are blossoming, and are ready to host pollinating insects or to be pollinate by the wind. 

The one who plants without this frost blanket will barely have started planting when the plants under INVERNAVELO® are at this stage. 

This grower will arrive at the martket with others competidors. Meanwhile the grower that uses INVERNAVELO® can preparing other crop cycle.

INVERNAVELO as insect protection

This fabric permits evaporation and the passage of air, but acts as a very efficient barrier against insect. Even the whitefly will can´t past it to the row that is cover and protect by INVERNAVELO. 

By preventing plants from attracting thrips and whiteflys, which cause viral diseases. By transmitting them through physical contact, and by tying this together with the fact that we are advancing growth by several weeks, means that we are saving agrochemicals, producing organically, and harvesting at a time when the market is fighting for our produce.

Rain damage and how INVERNAVELO® keeps the impact of rain and wind from knocking down plants

Upon install the INVERNAVELO® frost blanket the length of the row (be it use sticks, a system with twine, trellis netting, wire, or U-shaped bars invert over the row), the plant or seedling is protect from the devastating effects of heavy rain, or, even worse, torrential rain when the weight of the water knocks down the leaves or bends over the plant putting it into contact with the ground and thereby exposing it to fungal diseases. 

The wind can also cause this kind of damage to plants left exposed to the elements. The fabric of the INVERNAVELO® row cover acts as a windbreaker and as a shock absorber for raindrops or hail that can fall with great velocity during a storm. 

Nevertheless, once on the fabric, the rain can pass through and help us with its moisture to bring vitality to the plant.

INVERNAVELO® as a means for saving irrigation water

Finally, it is necessary to mention the properties of the INVERNAVELO® frost blanket in regards to its capacity to keep just the right amount of moisture trapped so that the plant will develop without the development of fungi. 

Especially in arid areas where water becomes scarce, covering the rows with this fabric will help in maintaining a relatively optimal moisture level for crops like tomatoes or cucumbers that need it.
