Physical and chemical variables analysis for clustering of soils in the longitudinal dunes of Sandy Pampa, Argentina
(Springer, 2016-08)The Sandy Pampa landscape was built on ancient dune-shaped landforms, which persist today and affect the characteristics of the soil in different sectors of the dunes. Based on their topographic position, different soils ... -
Soil properties evaluation in horticultural farms of Florencio Varela, Buenos Aires, Argentina
(Springer, 2018-06)The south of the green belt of Buenos Aires is one of the most important producers of fresh vegetables in the province. Only few of the horticultural farmers receive professional agronomic advice. For this reason, an excess ... -
Cover crops in the Southeastern region of Buenos Aires, Argentina: effects on organic matter physical fractions and nutrient availability
(Springer, 2018-06)In the Southeastern region of Buenos Aires province, soybean monoculture has led to a decline in soil organic matter (SOM) levels in soil, mostly the labile fractions. The reduction of SOM has a negative impact on the soil ... -
Efecto a corto plazo de la inclusión de vicia y trigo como cultivos de cobertura sobre el C, N y P en distintas fracciones de la materia orgánica, y la disponibilidad de macro y micronutrientes
(2018-08)La mayor participación de la soja entre los cultivos de verano sumada a los largos períodos de barbecho otoño-invernales han dado como resultado una importante reducción en el aporte de residuos y consecuentemente del ... -
Paenibacillus sp. A59 GH10 and GH11 extracellular endoxylanases: application in biomass bioconversion
(Springer, 2018-03)The cost-efficient degradation of xylan to fermentable sugars is of particular interest in second generation bioethanol production, feed, food, and pulp and paper industries. Multiple potentially secreted enzymes involved ... -
Soil organic carbon, macro- and micronutrient changes in soil fractions with different lability in response to crop intensification
(Elsevier, 2018)Soils under no tillage have experienced unfavorable changes, mainly due to current agricultural practices that consist in monocultures that leave little residue cover. The inclusion of grass as cover crops during the winter ... -
Evaluación del crecimiento y estado nutricional de híbridos interespecíficos de Eucalyptus sometidos a estrés por anegamiento y salinidad = Evaluation of growth and nutritional status of interspecific hybrids of Eucalyptus subjected to waterlogging and salinity stress
(Asociación Argentina de la Ciencia del Suelo, 2016)Se realizó un experimento en condiciones controladas durante 90 días para estudiar la respuesta de dos combinaciones híbridas de Eucalyptus (Eucalyptus grandis x Eucalyptus camaldulensis y Eucalyptus grandis x Eucalyptus ... -
Including spatial correlation in structural equation modelling of soil properties
(Elsevier, 2018-06)Digital soil mapping techniques usually take an entirely data-driven approach and model soil properties individually and layer by layer, without consideration of interactions. In previous studies we implemented a structural ... -
Efectos del fuego en la matriz del suelo : consecuencias sobre las propiedades físicas y mineralógicas
(2018-04)Los incendios constituyen disturbios de muy diverso origen y variadas implicancias. Además de los efectos sobre la vegetación, los incendios pueden afectar los componentes y las propiedades de los suelos. Las modificaciones ... -
Estimating Net Primary Productivity and Carbon Inputs by Soybean Crops in Argentina
(2017)Monitoring crop net primary productivity (NPP) and its proportion returned to soil in the form of carbon (C) input is vital to better understand the ecological responses to environmental and anthropogenic changes. However, ... -
Aridity and overgrazing have convergent effects on ecosystem structure and functioning in Patagonian rangelands
(2018-02)Over 65% of drylands are used for grazing of managed livestock. Understanding what drives grazing effects on the structure and functioning of rangelands is critical for achieving their sustainability. We studied a network ... -
Estimación de la pérdida de suelo por erosión hídrica en la República Argentina
(Ediciones INTA, 2017)La obra que se presenta, constituye un aporte relevante en la dirección mencionada, al estimar las tasas de pérdida de suelo por erosión hídrica en todo el territorio nacional, definir las tolerancias de erosión para cada ... -
Multivariate mapping of soil with structural equation modelling
(2017-09)In a previous study we introduced structural equation modelling (SEM) for digital soil mapping in the Argentine Pampas. An attractive property of SEM is that it incorporates pedological knowledge explicitly through a ... -
Génesis de suelos en un sector del piedemonte aluvial del Chaco salteño
(2012-12)Se estudia la relación suelo-paisaje, las propiedades físico-químicas y la composición mineralógica de diferentes suelos dentro del cono aluvial del río Del Valle, en el borde occidental del Chaco salteño, en la provincia ... -
A new soil-landscape approach to the genesis and distribution of typic and vertic Argiudolls in the Rolling Pampa of Argentina
(Springer, 2016)The Rolling Pampa is one of the several subregions of the large Pampa plains in central Argentina. The most extensive and representative soils in the area are Typic Argiudolls, together with a smaller proportion of Vertic ... -
Mapping the soils of an Argentine Pampas region using structural equation modeling
(2016-11)Current digital soil mapping (DSM) methods have limitations. For instance, it is difficult to predict a large number of soil properties simultaneously, while preserving the relationships between them. Another problem is ... -
Catabolic response and phospholipid fatty acid profiles as microbial tools to assess soil functioning
(2016-12)Microbial properties may help to provide an integrated view of changes in soil functioning associated with soil management or soil status. The fatty acid profiles of membrane phospholipids (PLFA) can give the composition ... -
Pedigree comparison highlights genetic similarities and potential industrial values of sugarcane cultivars
(2017-06)Cultivar pedigrees from two sugarcane origins, 9 Argentine (AR) and 7 American (AM) have been reconstructed, and their genetic similarities (based on coefficient of parentage, COP, estimates) show an average of 0.206 ± ... -
Calidad de la materia orgánica y disponibilidad de macro y micronutrientes por la inclusión de trigo como cultivo de cobertura
