      Salazar Guerrero, Osvaldo; Hansen, Søren; Abrahamsen, Per; Hansen, Karin; Gundersen, Per (Elsevier, 2013)
      Land use change alters water and element cycles, but the changes in these cycles after conversion, for example, from cropland to forest are not fully described in hydrological and nutrient transport models, which usually ...

      A critical aspect of predicting soil organic carbon (SOC) concentrations is the lack of available soil information; where information on soil characteristics is available, it is usually focused on regions of high agricultural ...
    • Digital soil mapping and GlobalSoilMap. Main advances and ways forward 
      Arrouays, Dominique; Poggio, Laura; Salazar Guerrero, Osvaldo; Mulder, Vera Laetitia (Elsevier, 2020)
      In this concluding paper, we summarize the main advances coming forward from the joint conference of the International Union of Soil Sciences (IUSS) Working Groups (WG) "Digital Soil mapping" (DSM) and "GlobalSoilMap". We ...
    • Evaluation of soil fertility and fertilisation practices for irrigated maize (Zea mays L.) under Mediterranean ... 
      Nájera de Ferrari, Francisco; Tapia Fernández, Yasna; Baginsky Guerrero, Cecilia; Figueroa, V.; Cabeza Pérez, Ricardo; Salazar Guerrero, Osvaldo (Soc Chilena Ciencia Suelo, 2015)
      The main aim of this study was to carry out an evaluation of soil fertility and fertilisation practices for irrigated maize (Zea mays L.) under Mediterranean conditions in central Chile. Soil samples were collected from ...
    • Field Monitoring of 2010-Tsunami Impact on Agricultural Soils and Irrigation Waters: Central Chile 
      Casanova Pinto, Manuel; Salazar Guerrero, Osvaldo; Oyarzún, Irene; Tapia Fernández, Yasna; Fajardo, Mario (Springer, 2016)
      An in situ post tsunami study was conducted to assess the effect of water management and rainfalls in soil properties and water quality at a low-lying coastal area of central Chile affected by Mw8.8 Earthquake Tsunami the ...
    • Inorganic nitrogen losses from irrigated maize fields with narrow buffer strips 
      Salazar Guerrero, Osvaldo; Rojas, Claudia; Avendaño, Fernando; Realini, Piero; Nájera de Ferrari, Francisco; Tapia Fernández, Yasna (Springer, 2015)
      Vegetated buffer strips (BS) can help prevent nitrogen (N) losses from fields by subsurface lateral flow, thus protecting water resources. The purpose of this study was to determine if narrow BS would effectively remove ...
    • Monitoring of nitrate leaching during flush flooding events in a coarse-textured floodplain soil 
      Salazar Guerrero, Osvaldo; Vargas, Juan; Nájera de Ferrari, Francisco; Seguel Seguel, Oscar; Casanova Pinto, Manuel (Elsevier, 2014)
      The demand for foods in central Chile is increasing and arable land is expanding rapidly onto floodplain soils, which are being cleared for maize cultivation. After harvest, a significant amount of residual nitrogen (N) ...
    • Morphophysical pedotransfer functions for groundwater pollution by nitrate leaching in Central Chile
