Rural producers and agricultural advisors in Paraná state will be able to rely on BioAS soil technology from now on. This technique was initially orchestrated for annual crops of grain and fiber in the Cerrado, and from now on it is also available for crops in Paraná. BioAS PR technology will be launched on May 17, 3:30 p.m., at the 9th Brazilian Soybean and Mercoja 2022 Conference.
This expansion was possible because interpretation algorithms were developed for the enzymatic activity levels (high, medium and low) specific to Parana soils under annual crops. “We are working so that the technology reaches more and more areas of Brazil as well as other crops, such as sugar cane, coffee, and pastures,” says Embrapa Cerrados researcher Ieda Mendes, Bioindicators Project Leader.
Technology – Launched in July 2020, after twenty years of studies, the BioAS technology was developed with the goal of filling a gap in lab soil analyses. Until then, only factors related to chemistry and physics had been evaluated. With BioAS, it became possible to reveal aspects related to the biological performance of soils, which until then had gone unnoticed in fertility analyzes, but could affect the economic performance of crops and the sustainability of agro-ecosystems.
The technology consists of the analysis of two enzymes (beta-glucosidase and arylsulfatase) associated with productive potential and sustainable land use. They are related, respectively, to the carbon and sulfur cycles and act as biomarkers of soil health. Explains researcher from Embrapa Cerados, Fabio Bueno.
According to him, large amounts of these biomarkers are indicative of appropriate and sustainable production systems or soil management practices. On the other hand, low values are a warning to the farmer to re-evaluate the production system and adopt good management practices. “BioAS technology allows the farmer to know whether the management system adopted on the farm promotes health or favors disease of the soil in which he grows his crops,” he asserts.
BioAS technology is available to Brazilian farmers through a network of Embrapa-enabled laboratories. Laboratories from all over Brazil can gradually integrate the Embrapa BioAS network. They connect to Embrapa’s servers through a web platform called the BioAS Soil Quality Interpretation Module, which also includes the calculation of soil quality indicators (IQS).
IQS is calculated based on both chemical and biological properties (IQSFERTIBIO) and separately (IQSBIOLOGICAL and IQSQUÍMICO). The reference parameters and indicator tables involved in the BioAS technology are systematically updated, based on the Embrapa Experiment Network to calibrate and develop this technology. As a result, lab clients will always have results containing reports with an updated interpretation by Embrapa, Harvest by Harvest.
“Now Paraná farms and laboratories that provide this type of soil analysis service can count on something more regional and suited to the peculiarities of the country,” says Marco Antonio Nogueira, researcher at Embrapa Soja. According to him, it is very important to calculate this table for the state of Paraná because it allows the most realistic interpretation of the state of the state. “Bio-analysis comes to the aid of the producer from Parana, who will be able to have this refinement in the interpretation of the results of their soil analysis. This kind of interpretation is unprecedented in the world. This great contribution has now reached our state and will certainly help the agriculture in Parana “, confirms .
Database Expansion – Interpretation algorithms have been calibrated to the Soil Bioanalysis technology and are currently available exclusively for annual crops in the Cerrado biome, now in the state of Paraná. However, researchers participating in BioAS have assessed that opening the platform might be interesting to expand the database for research purposes, without impact in terms of agricultural recommendation. “From now on, data from other countries and cultures may be submitted to the platform as long as the data entry actually reflects the culture and region of origin of the soil sample,” said Embrapa agrobiologist Guilherme Chaer.
