Agro em Debate talks about bean cultivation and the importance of sustainability

Agrivalle, a company in the bioinputs segment in Brazil, held on March 25th the 2nd edition of Agro em Debate on the importance of sustainability for bean cultivation. With a 100% digital format and broadcast live on the company's social networks, the project brought discussions on topics relevant to the agricultural market, providing an environment for the exchange of knowledge and information.

On the occasion, Thales Facanali, development manager, and Eduardo Bernardo, research director, both from Agrivalle, brought to the discussion a very relevant topic, the soil, its diversity and multifunctionalities, and how to assist in its regeneration. "We need to talk about soil sustainability and how to keep it "alive" through its regeneration. Much of our soil, what prevails is an environment of an imbalanced system. We have plant health problems, with microorganisms that are not beneficial, with the capacity to persist in the soil. They can remain in the soil, in the form of a resistance structure, for more than 10 years. Cases, for example, of white mold, in bean, tomato and other crops", warns Eduardo Bernardo

During the debate, both brought the perspectives and role of Agrivalle to continue improving crops, in order to meet high production demands and promoting greater efficiency and sustainability through the soil-plant system, for longevity in bean and pulse cultivation. And they brought the soil regeneration pillar as one of the main ones, since there are microorganisms that negatively affect root development. "Today we operate in a grass and legume rotation system and, in itself, this is another reason to look at the quality of the land. Some phytopathogens proliferate and pass from crop to crop. Therefore, the farmer needs to look at the soil as its heritage, and devise strategies for its sustainability. This is crucial to its production success and profitability. There is no point in planning the culture and its rotation, if this soil is not balanced, the culture implemented will suffer in its establishment and development, negatively affecting productivity", advises Thales.  

As explained by Thales and Eduardo, beans, as well as soybeans, brachiaria, corn and sorghum, are potentially host crops for soil pathogens and this can harm or impede the development of seeds and a healthy root system. "Pratylenchus, for example, has a multiplication that every 35 to 40 days a female lays 200 eggs. In the case of Meloidogyne, the potential is 600 to 800 eggs every 35 to 40 days. White mold (Sclerotinia sclerotiorum) , in a bean cycle, its pathogen can multiply up to 6 times. In other words, either we think of a strategy to reduce the persistence of these pathogens in the soil, or we can make productivity unfeasible", explains Eduardo. 

The root system itself attracts diseases and nematodes, as it is a source of food and this happens through chemical signals. Therefore, it is very important to maintain a strategy that allows diversified control so that the imbalance is managed correctly. "There is a great risk of having a high number of non-beneficial microorganisms parasitizing the roots of plants, if there is no control and strategy. Of course, there are also beneficial microorganisms in the soil, but without planning, this leaves room for the bad ones to be more prevalent. quantity, causing severe root problems. And we know that every root problem has its occurrence correlated with the biological imbalance of the soil", advises Eduardo. 

To establish a beneficial microbiota it is necessary to use more than one form of action and therefore, microorganisms used together can help control more than one problem and guarantee a prolonged residual effect. "We have mechanisms that induce the plant to produce defense compounds, hyperparasitism, antibiosis and others acting on the different phases of the parasites and, when we combine several actions for pathogens and diseases, improving diversity in the soil, being able to establish a broad spectrum of action. And the The most interesting thing is that this is possible for the different types of production environment, and different agricultural regions and types of soil that we have in Brazil", concludes Thales.

Technology package

Profix is ​​a nematicide with two bacteria and a fungus that act to treat seeds and planting furrows and Shocker contains two bacilli and a fungus that also act towards soil regeneration. Both, when added to productive land, can protect the roots from surrounding phytopathogens, reducing plant stress and converting it into productivity. 

For extra gain, biostimulants of organic origin are recommended, which improve rooting and serve as a substrate for the microbiota. In partnership with Professor Fernando Andreote from Esalq/USP, we were able to see that the increase in enzymes could mean that the biostimulant will serve both to feed the plant and to nourish the beneficial microorganisms in the soil, which could promote local biota even more healthy. 

Agriculture in Debate

Agro em Debate, is an initiative designed and carried out by Agrivalle, which will bring together, over the next few months, cycles of lectures and technical debates broadcast online and live via the company's official YouTube channel, presenting the best tools, technologies and innovative solutions for help producers produce more and more with better quality.
