Biological activity of soils cultivated with topinambur inoculated with Azospirillum Brasilense and micorrícic fungi.

Soil samples were collected in the province of Catamarca in lots grown with topinambur (Helianthus tuberosus L.) at the time of implantation and harvest during four agricultural cycles. The tubers were treated with Azospirillum brasilense, mycorrhizal fungi or both microorganisms. Tubers correspondi...

ACTIVIDAD BIOLÓGICA DE SUELOS CULTIVADOS CON TOPINAMBUR INOCULADOS CON Azospirillum brasilense Y HONGOS MICORRÍCICOS DI BARBARO, G. ANDRADA, H. DEL VALLE, E. BRANDÁN DE WEHT, C. Helianthus tuberosus biological activity soils Catamarca Helianthus tuberosus actividad biológica suelos Catamarca Soil samples were collected in the province of Catamarca in lots grown with topinambur (Helianthus tuberosus L.) at the time of implantation and harvest during four agricultural cycles. The tubers were treated with Azospirillum brasilense, mycorrhizal fungi or both microorganisms. Tubers corresponding to the controls were not inoculated with these microorganisms. Total Biological Activity (ABT) was determined by Fluorescein Diacetate Hydrolysis to the collected samples. The ABT of the soil was affected by the different treatments of the crop. Microbial inoculation raised the ABT of the studied soils, differing statistically with the controls. Signifi cant differences were also observed between the ABT of the soils at the beginning of the crop with the values recorded at their harvest. The inoculation of topinambur tubers with A. brasilense and mycorrhizal fungi affects the ABT of cultivated soils. Muestras de suelo fueron colectadas en la provincia de Catamarca en lotes cultivados con topinambur (Helianthus tuberosus L.) al momento de implantación y cosecha durante cuatro ciclos agrícolas. Los tubérculos fueron tratados con Azospirillum brasilense, hongos micorrícicos o ambos microorganismos. Tubérculos correspondientes a los testigos no se inocularon con estos microorganismos. Se determinó la Actividad Biológica Total (ABT) por Hidrólisis del Diacetato de Fluoresceína a las muestras colectadas. La ABT del suelo fue afectada por los diferentes tratamientos del cultivo. La inoculación microbiana elevó la ABT de los suelos estudiados, difiriendo estadísticamente con los testigos. También se observaron diferencias signifi cativas entre la ABT de los suelos al inicio del cultivo con los valores registrados a la cosecha de los mismos. La inoculación de tubérculos de topinambur con A. brasilense y hongos micorrícicos afecta la ABT de los suelos cultivados.
