Sustainable management practices

The implementation of sustainable agricultural practices is essential for soil preservation and increased agricultural productivity. Techniques such as crop rotation and green manure play crucial roles in this process, ensuring adequate management of available natural resources.

Crop rotation

Crop rotation is a fundamental practice that prevents the depletion of soil nutrients by diversifying the type of crops grown throughout the harvests.

This method not only improves the soil fertility, but also reduces the incidence of pests and diseases. In regions such as the Cerrado, for example, it is recommended to plant cultivars that are more tolerant to diseases during the rainy season.

Digital tools such as those from BASF’s xarvio® Digital Farming Solutions can significantly assist in the management of this technique, optimizing seed distribution and soil nutrition.

Green manure

Green manure involves the use of specific plants to enrich the soil with organic matter and nutrients, promoting biological activity.

This practice is beneficial in several locations, such as in Southern Brazil, where planting medium and late cycle cultivars can mitigate the effects of drought in the vegetative phase.

Furthermore, green manure helps to conserve the soil and maintain its structure, being an effective strategy in the context of sustainable agricultural practices.

A detailed analysis of the practices adopted in several Brazilian states reveals interesting data on agricultural and livestock production:

These data, combined with the efficient use of techniques such as crop rotation and green manure, demonstrate the importance of sustainable agricultural practices for the national agricultural economy.

Organic fertilizers and fertilisers

Organic fertilizers are essential for maintaining the soil health in the long term. They help to preserve the natural soil nutrients and improve their structure, ensuring sustainable agricultural production.

Home composting

THE composting homemade is a simple and effective practice that allows you to transform kitchen and garden waste into organic fertilizer rich in nutrients. This process not only reduces the amount of household waste but also enriches the soil with natural soil nutrients, promoting more sustainable agriculture.

Use of animal manure

The use of animal manure as organic fertilizer is another traditional practice in agriculture. This method enriches the soil, improving its fertility and helping with water retention. In addition, animal manure provides natural soil nutrients, essential for plant growth.

The importance of soil pH

The understanding of Soil pH is crucial to any effective agricultural practice. The soil acidity and your alkalinity are determining factors in the availability of nutrients for plants.

A soil with an unbalanced pH can limit crop growth, negatively affecting productivity.

According to studies by the Federal University of Paraná (UFPR), crop rotation is a fundamental technique for diversification in agricultural planting, avoiding soil exhaustion and maintaining fertility. In this context, the pH adjustment of the soil is vital to ensure soil health.

There are four main types of agricultural limestone used to correct the soil acidity: calcitic limestone, magnesian limestone, dolomitic limestone and filler limestone.

The correct application of these limestones can bring several benefits, including improving soil structure and stimulating microbial activity.

To maximize the pH adjustmentIt is recommended to apply lime approximately three months before planting. This practice is corroborated by several sources, including Brasmax Genética, which explains how crop rotation and continuous monitoring of soil pH are essential for a healthy crop.

In addition, the use of limestone helps reduce the toxicity of elements such as aluminum and manganese, promoting a more sustainable environment for plant growth. Based on the practices recommended by Agropec News, planting onions or other crops requires careful pH management to optimize productivity.

In this way, the pH adjustment Soil conservation not only improves plant health, but also plays a crucial role in agricultural sustainability. It is through these practices that more efficient and environmentally friendly production can be achieved.

Benefits of plant cover

Implement the ground cover through vegetation brings numerous benefits not only for environmental preservation, but also for the health of crops. This effective method acts as a natural barrier against erosion, in addition to optimizing moisture retention in the soil.

Erosion protection

THE erosion prevention is a crucial factor in maintaining soil integrity. The presence of plants on the surface reduces the impact of heavy rain and winds, minimizing the loss of fertile soil. This is particularly important in regions facing intense climate change, as pointed out by the UN, thus ensuring the productive stability of crops.

Moisture retention

THE water conservation is another vital benefit provided by plant cover. Plants help retain moisture in the soil, reducing evaporation and making the environment more favorable for crop growth.

On properties such as those located in the North of Rio Grande do Sul, where efficient management of water resources is essential, the practice has shown positive results.

The data shows that approximately five properties in this region have designated plots of land to experiment with covered soil management, showing a growing trend in the adoption of this sustainable practice.

The Operação 365 program has also contributed to promoting sustainability and productive stability in crops, encouraging the use of good management practices.

Biomass and biochar: natural solutions

The use of biomass and biochar emerges as an innovative and natural solution for soil improvement. These features not only help increase the soil fertility, but they also play a crucial role in carbon sequestration, counteracting the effects of climate change.

Studies have shown that transitioning from conventional to regenerative agricultural practices can lead to substantial increases in carbon sequestration. Regenerative practices can sequester up to several tons of carbon per hectare per year, making a significant contribution to mitigating greenhouse gas emissions. biochar, for example, can improve soil structure and retain carbon for hundreds or even thousands of years.

Practices such as composting and the application of biochar are particularly effective in increasing soil carbon content, improving soil fertility and overall health.

The gasification of biomass and the pyrolysis method for production of biochar are key processes for transforming these materials into valuable resources for soil improvement.

Below we present a summary of the practices and their implications:

Adopting these practices is essential for farmers who want to not only maintain but also improve soil health and productivity in the long term. Above all, improving soil structure and its ability to retain nutrients and water is a significant benefit, promoting more sustainable and efficient agriculture.

Soil monitoring and analysis

THE soil monitoring and analysis are essential steps to ensure soil quality and health. Carrying out a soil test regular monitoring helps identify nutrient deficiencies, contamination and organic matter levels that directly influence plant growth.

In the Northeast of Brazil, milk production is significant, reaching 5.7 billion liters in 2022, representing 16.5% of the national total. Innovative projects, such as the implementation of the first robotic milking at Fazenda Haras Tripuí, Bahia, are transforming the region.

The implementation of advanced techniques for soil health diagnosis was one of the focuses of this project, which foresees a daily production of 10,000 liters of milk, with 140 lactating cows in the first phase and capacity for 280 cows with the adoption of four robots.

These projects are improving not only the quality of the milk produced, but also the efficiency of agricultural practices, thanks to in-depth soil analysis that optimizes the production of bulk and silage. The Haras Tripuí Farm, for example, has accumulated 2,600 tons of silage stored for the herd.

To illustrate the impacts and challenges, see the table below highlighting QGX Digital's performance after being analyzed by Delfia:

The benefits of soil health diagnosis are evident, promoting more efficient and sustainable agriculture. Soil integrity and health directly reflect crop productivity and the quality of final products, benefiting producers and consumers.

How to improve soil quality through biodiversity

Integration of Different Plants

The integration of diverse plants into agricultural systems contributes to the diversity of cultures, essential for creating richer and more balanced soils. Projects such as the Cacau Floresta Project in Bahia promote the cultivation of cocoa in agroforestry systems, encouraging regenerative practices.

1. Increased biodiversity: makes agricultural systems more resilient to pests and diseases.
2. Improved moisture retention: ILPF experimental areas showed an increase of between 0.1 mm and 0.7 mm of moisture retained per centimeter of soil.
3. Soil sustainability: systems such as those at Fazenda da Toca, which integrate agroforestry practices and organic cultivation, demonstrate improvements in indicators of water availability and aeration.

Grazing Animals in Crop Rotation

THE animal integration in agriculture also contributes to the soil biodiversity. Rotational grazing, used by Joel Salatin at Polyface Farm, exemplifies how the presence of animals can enrich the soil.

• Soil macroporosity: Increase of 50% compared to pastures not cultivated for more than 30 years.
• Soil aeration: Experiments with eucalyptus and native species show greater aeration capacity compared to pasture reference areas.
• Available water capacity: In Morrinhos, the ILPF system increased water capacity due to the increase in micropores.

Through these practices, we can observe a significant improvement in soil biodiversity, resulting in healthier and more productive agricultural systems. Promote diversity of cultures and the animal integration in agriculture are essential strategies for a balanced and sustainable agroecosystem.
