Action of different corrective in microbian soil biomass

Abstract

Microorganisms are important biological indicators, responding quickly to changes triggered by actions performed by man. In Brazil, due to a soil solution resource, perform the calibration process using the appropriate development of agricultural crops. The neutralization of the soil solution can influence a microbial population and the processes mediated by it. Thus, we aim to evaluate how changes in the soil microbial population over time triggered by the application of different agricultural assets. For this, a superficial layer of a clayey soil was collected and through the need for calibration applied to the following procedures: T1 - Control; T2 - Conventional calcite limestone; T3 - Se Power; T4 - Se Power Bio, with 4 repetitions/treatment. Samples for microbiological analysis were collected before the application of treatments and up to 30, 60 and 90 days after application. 10 g of soil were weighed every 5 cm in depth and these were serially diluted to 10^-4 where a 0.1 ml aliquot was taken and disassembled in BDA medium. The application of soil amendments provides soil pH variation in the 0-5 cm layer during the evaluated period, with a maximum value of 30 days after application. There were changes both in the population of bacteria and in fungi present in the amounts of soil at all depths and in the applied adjustments. Treatment with the product Se Power Bio shows a different performance in the microbiota, possibly due to the presence of bacterial bacteria that are not the same, which can favor the sustainability of agro-environmental production systems.
