      Maize (Zea mays L.) is one of the most susceptible crops to zinc (Zn) deficiency. However, in much of the world, soil Zn tests are poorly calibrated, and thus determining a critical soil test, level for Zn is challenging. ...

    • Does nitrogen fertilization rate, timing and splitting affect sunflower yield and grain quality? 

      Tovar Hernández, Sergio; Carciochi, Walter; Diovisalvi, Natalia; Izquierdo, Natalia; Wyngard, Nicolás; Barbieri, Pablo; Reussi Calvo, Nahuel Ignacio (Wiley, 2023-02)
      Nitrogen (N) deficiency could have a negative effect on sunflower (Helianthus annuus L.) yield and grain quality. Therefore, it is necessary to adjust the optimum rate, timing, and frequency of N fertilization to improve ...

    • Economic optimum nitrogen rate analysis for feed and malting barley 

      Reussi Calvo, Nahuel Ignacio; Carciochi, Walter; Prystupa, Pablo; Queirolo, Ignacio; Sainz Rozas, Hernan Rene (Wiley, 2022-07-10)
      The malt industry has specific requirements for malting barley (Hordeum vulgare L.) grain protein concentration (from 9.5 to 13%) and size (>85%), which could be affected by nitrogen (N) fertilization. We aimed to (a) ...

    • Holistic Assessment of Calcium Fertilization in Potato: Diagnostic, Productivity, and Tuber Quality 

      Giletto, Claudia; Kloster Erreguerrena, M.; Ceroli, Paola Susana; Carciochi, Walter; Silva, Sandra; Rodríguez, Silvia; Salvagiotti, Fernando; Reussi Calvo, Nahuel Ignacio (Springer Nature, 2023)
      Calcium (Ca) deficiency could negatively affect potato (Solanum tuberosum L.) tuber yield and quality. Therefore, it is required to develop Ca diagnostic methods and assess the impact of Ca fertilization on tuber yield and ...

    • Methods to determine nitrogen in sunflower grains 

      Diovisalvi, Natalia; Izquierdo, Natalia; Echeverria, Hernan Eduardo; Garcia, Fernando; Reussi Calvo, Nahuel Ignacio (Asociación Argentina de la Ciencia del Suelo, 2021-12)
      In sunflower, grain oil concentration (OG) determines oil industrial yield and protein concentration (PG) determines the protein of by-products as pellets and meals (PM). There are various methodologies to quantify total ...

    • Monitoring Corn Nitrogen Concentration from Radar (C-SAR), Optical, and Sensor Satellite Data Fusion 

      Lapaz Olveira, Adrián; Sainz Rozas, Hernan Rene; Castro Franco, Mauricio; Carciochi, Walter; Nieto, Luciana; Balzarini, Mónica; Ciampitti, Ignacio; Reussi Calvo, Nahuel Ignacio (Multidisciplinary Digital Publishing Institute (MDPI), 2023-02)
      Corn (Zea mays L.) nitrogen (N) management requires monitoring plant N concentration (Nc) with remote sensing tools to improve N use, increasing both profitability and sustainability. This work aims to predict the corn Nc ...

    • Monitoring corn nitrogen nutrition index from optical and synthetic aperture radar satellite data and soil available nitrogen 

      Lapaz Olveira, Adrián; Castro Franco, Mauricio; Sainz Rozas, Hernan Rene; Carciochi, Walter; Balzarini, Mónica; Avila, Oscar; Ciampitti, Ignacio; Reussi Calvo, Nahuel Ignacio (Springer, 2023-08)
      Nitrogen (N) nutrition index (NNI) is a reliable indicator of plant N status for field crops, but its determination is both labor- and cost-intensive. The utilization of remote sensing approaches for monitoring N, mainly ...

    • Prognosis and diagnosis of sulfur status in maize by plant analysis 

      Carciochi, Walter; Reussi Calvo, Nahuel Ignacio; Wyngaard, Nicolás; Divito, Guillermo; Eyherabide, Mercedes; Echeverria, Hernan Eduardo (Elsevier, 2019-05)
      The analysis of sulfur concentration (SC) and nitrogen to S ratio (N/S) in plant tissue are some of the suggested tools to evaluate S deficiency in maize (Zea mays L.). However, the convenience of one over the other and ...
