Brazilian agriculture faces climate challenges, but sustainable practices can help soil recovery

Expert highlights the importance of good management practices to restore soil health and ensure food security amid extreme conditions

The extreme weather conditions that have affected Brazil in recent months have presented new and significant challenges for farmers. The heavy rains that have hit Rio Grande do Sul and the fires observed in various parts of the country have severely impacted soil quality, causing loss of essential nutrients and degradation of soil structure. In this scenario, there is an increasing need for innovative and sustainable practices to restore soil health and ensure the continuity of activities in the countryside.

 

“We’ve experienced severe droughts that have resulted in devastating fires, while other regions, especially the south of Brazil, have faced intense rainfall and the overflow of rivers. This scenario damaged the soil in many areas, leading to erosion of its surface layer. Now, it is crucial that producers look for alternatives to restore productive potential and guarantee food security,” says agronomist and Strategic Marketing Manager at Agrobiológica Sustentabilidade, Bruno Arroyo.

 

For soils affected by flooding, Arroyo suggests a systematic approach, which includes correcting the surface layer and detailed analysis to adjust pH and nutrients. The use of correctives, such as lime and gypsum, is vital for improving nutrient percolation and revitalizing fertility. In addition, cover crops, such as turnip rape and buckwheat, play a key role in protecting the soil from erosion and provide better aeration, which is crucial for root health.

 

In areas affected by fires, soil recovery requires specific strategies. The application of conditioners and bio-inputs re-establishes the microbiota devastated by the fire, creating an environment conducive to regeneration. The use of straw and cover crops significantly reduces the effects of erosion, as well as strengthening the roots, which are essential for soil structure. To replace lost nutrients, composting and green manures are indispensable, enriching the soil with vital organic matter.

 

The selection of cover crops, suitable for both situations, must also take into account regional particularities. “In the central region, plants like brachiaria, with deeper roots, are effective at aerating and stabilizing the soil. In the south, winter crop plants ensure soil protection and help maintain fertility during rainy periods, creating an ideal environment for regeneration. Mixes of green manures, which fit each reality and each area, are also applicable,” he explains.

 

In addition, the use of compost and beneficial microorganisms is crucial to restoring the soil’s microbiological potential. These agents not only improve soil structure, but also contribute to the success of crops such as soybeans, cereals and sugar cane, especially in areas affected by fires. The activation of microbiological and enzymatic processes allows plants to establish themselves more effectively, promoting healthy and sustainable harvests.

 

It’s worth mentioning that when it comes to bio-inputs, Brazil is one of the countries that makes the most use of biological tools and, when it comes to soil management, producers have several tools based on fungi, bacteria and mycorrhizae to protect their crops, such as bionematicides, biofungicides, nutrient solubilizers, such as phosphorus, and even bacteria that help mitigate stresses. These solutions can be applied from seed treatment or in the sowing furrow. More and more companies are investing in improved formulations and advanced research that is bringing economic gains to agriculture and optimizing the farm’s operations, with solutions that are compatible with the conventional management previously adopted.

 

This is therefore a decisive moment for Brazilian agriculture. Adopting sustainable and innovative practices will not only help recover affected soils, but will also guarantee resilient agricultural production in the face of climate change. “The mobilization of farmers, experts and institutions is key to meeting the current challenges and building a more secure and sustainable future for our sector,” Arroyo concludes.
