Fracciones de fósforo edáfico bajo diferentes manejos = Phosphorus fractions under different managements por Giannini, Ana Paula, Andriulo, Adrian Enrique, Wyngaard, Nicolás, Irizar, Alicia Beatriz

“…La reserva de PT disminuyó aún más al incrementarse los años de agricultura debido principalmente a reducciones en el Pi y también por la brusca caída del extractable (Pe) (92%), el cual se ubicó debajo de los valores típicos reportado para la subregión pampa ondulada. El sistema de cultivo predominante pone en riesgo el estado nutricional de los suelos y la productividad de los agroecosistemas.…”

Sampling scheme optimization to map soil depth to petrocalcic horizon at field scale por Domenech, Marisa Beatriz, Castro Franco, Mauricio, Costa, Jose Luis, Amiotti, Nilda Mabel

“…The method was tested with real data at four agricultural fields localized in the southeast Pampas plain of Argentina. The purpose of the method was to minimize the sample dataset size to map soil depth to petrocalcic horizon based on ordinary cokriging, five calibration sample sizes (returned by Conditioned Latin hypercube –cLHS-), and apparent electrical conductivity (ECa) or elevation as variables of auxiliary information. …”

Contribution of Integrated Crop Livestock Systems to Climate Smart Agriculture in Argentina por Colazo, Juan Cruz, Herrera, Juan De Dios, Sager, Ricardo Luis, Guzman, Maria Laura, Zaman, Mohammad

“…So, our objectives were to (i) compare SOC and its physical fractions in ICLS and CC, and (ii) evaluate the use of δ13C to identify the source of C of SOC in these systems in the Pampas region of Argentina. For that, we compared two farms, an ICLS and a CC having the same soil type and landscape position. …”
