Innovative methods for the disinfection of agricultural soils: keep your protected and healthy crops

Soil disinfection is an essential practice to ensure the health and productivity of crops. Maintaining a path -free of pathogens not only helps prevent diseases, but also improves the structure and fertility of the land, thus guaranteeing more abundant and better quality harvests. In this article, we present the most advanced methods for the disinfection of agricultural soils, their advantages and how to implement them safely and effectively.

MAIN DISINFECTION METHODS

There are several modern techniques for soil disinfection, each adapted to different situations and types of cultivation. Next, we detail the most relevant:

1. Solarization

This method is to use the heat of the sun to raise the temperature of the soil. When covering the terrain with a transparent plastic during the warmest seasons, it is possible to increase the temperature of the soil to levels that eliminate a large number of pathogens, as well as weeds and unwanted seeds. Solarization is especially effective in areas with high temperatures and is an economic and environmental technique.

Advantages of solarization:

• Low cost.
• It does not require the use of chemicals.
• Improves soil structure by eliminating harmful organisms without harming benefits.

2. Biofumigation

This method takes advantage of the natural properties of certain crops that, when decomposing, release compounds with fumigant capacity. Plants such as mustard or broccoli generate substances that act as natural fumigants, helping to reduce the presence of pathogens in the soil. In addition, biofumigation not only disinfects, but can also enrich the soil with additional nutrients.

Advantages of biofumigation:

• Sustainable and environmental respectful.
• It brings organic matter to the soil, improving its fertility.
• It is a method that can be combined with other integrated management systems.

3. Use of chemicals

The use of specialized fumigants and chemicals is an effective technique for soil disinfection when other methods are not enough. However, careful management of these products is essential, since their improper use can have serious consequences for both human health and the environment.

MOST USED PRODUCTS:

• Meticloropressed: Highly effective against fungi and some bacteria.
• Dazomet: Acts on a wide range of pathogens, including nematodes, fungi and weeds.

Although these products are effective, it is essential to follow security recommendations, such as the use of Personal Protection equipment (PPE) and the correct application in adequate climatic conditions to avoid dispersion.

Why disinfect the ground?

Soil disinfection is a key preventive practice that protects crops against a wide range of threats, such as pests, fungi and bacteria. Besides:

• Prevents diseases They could otherwise devastate your crops.
• Improve soil quality, promoting the beneficial microbial activity and maintaining an adequate structure.
• Increase productivity by allowing plants to grow in a healthier and less competitive environment.

When is the best time to disinfect the ground?

The ideal moment to disinfect the soil depends on the chosen method and the culture cycle. Generally, it is advisable to carry out disinfection before planting, especially if in the previous season problems with pathogens or weeds were detected. The crop rotation It is also a good time to implement these practices, since it interrupts the life cycle of the harmful organisms present in the soil.

Safety when using chemicals

If you decide to use chemicals for disinfection, it is vital to follow certain safety precautions:

• Always read labels: Follow the manufacturer's instructions on dosage and application to the letter.
• Use Personal Protection Team (EPP): Gloves, masks and glasses are essential to avoid direct exposure to toxic products.
• Consider climatic conditions: Avoid applying chemicals on suction or risk of rain, as they could disperse and affect unwanted areas.

Sustainable alternatives to chemical methods

If you prefer a more ecological and sustainable approach, there are several alternatives to chemicals:

• Crop rotation: By changing crops in each season, you can significantly reduce the presence of specific pathogens.
• Coverage crops: Planting species such as legumes or cereals can improve soil structure and limit the growth of harmful organisms.
• Biological control: Using natural fidders of pests or pathogens is an effective and environmental technique.

Environmental Impact and Regulations

The use of chemicals in agriculture has a direct impact on the environment. They can alter soil biodiversity, pollute groundwater and affect non -objective species. Therefore, it is important to opt for sustainable methods whenever possible and Comply with local regulations Regarding the use of chemicals, especially if you work in crops with organic certifications.

Costs associated with soil disinfection

The cost of disinfecting the soil varies according to the method you choose:

• Solarization: Low cost, since it only requires transparent plastic and a warm climate.
• Biofumigation: Moderate cost, depending on the crop used.
• Chemicals: Greater investment, since specialized products are usually expensive and require adequate equipment and EPP.

Conclusion

Disinfecting agricultural soil is an essential practice to protect your crops and guarantee its productivity. From solarization to the use of chemicals, there are several options according to your needs and the type of crop. Always consider the most sustainable alternatives and respect local regulations to minimize environmental impact and guarantee safety in your agricultural exploitation.

Are you ready to implement these methods on your farm? Your floor and your crops will thank you!
