Solarisation: Innovative Technique for Soil Disinfection

In the search for sustainable and effective solutions for crop soil disinfection, the innovative technique of “solarisation” has emerged. Its application not only promotes soil health, but also contributes to the preservation of the environment. In the following sections we will be able to see what this technique consists of and the various advantages of its implementation in crops.

What is Solarisation?

Solarisation is an agricultural technique that uses solar energy to disinfect the soil and control pathogens, weeds, and nematodes. It consists of covering the damp soil with transparent plastic for several weeks, preferably in the warmer months of the year. Under the plastic, solar radiation raises soil temperature to levels lethal to harmful organisms, while trapped moisture encourages beneficial microbial activity. Solarisation is in line with the principles of permanent agriculture, regenerative agriculture and organic agriculture.

Advantages of its use

Solarisation has several advantages, including its low cost and compatibility with organic production systems. In addition, it is effective in controlling soil diseases such as Fusarium and Verticillium, especially in crops such as tomatoes, peppers, and strawberries. However, it is important to note that its effectiveness may vary according to location and climate, and that it may temporarily affect the soil microbiota.

In terms of sustainability, solarisation minimizes the use of chemical biocides, thus contributing to the preservation of the environment and human health. In addition, by improving soil quality and increasing nutrient availability, this technique promotes more sustainable farming practices in the long term.

Conclusions

Solarisation is a promising tool for soil disinfection in agriculture, especially in regions such as Almeria, where the sun spends the winter, an ideal climate to take advantage of this type of technique.
