    • Assessing the effect of split and additional late N fertilisation on N economy of maize 

      Maltese, Nicolás; Carciochi, Walter Daniel; Caviglia, Octavio; Sainz Rozas, Hernan Rene; García, Mauricio; Lapaz, Adrián; Ciampitti, Ignacio; Reussi Calvo, Nahuel Ignacio (Elsevier, 2024-03)
      Context: In the temperate-humid region of Argentina, nitrogen (N) fertilisers in maize (Zea mays L.) are mainly applied around sowing, whereas N-splitting is rare and occurs during early vegetative stages. Splitting and ...

    • Assessment of nitrogen diagnosis methods in sunflower 

      Tovar Hernandez, Sergio; Diovisalvi, Natalia; Carciochi, Walter Daniel; Izquierdo, Natalia; Sainz Rozas, Hernan Rene; García, Fernando; Reussi Calvo, Nahuel Ignacio (American Society of Agronomy; Estados Unidos, 2021-04-20)
      Nitrogen deficiency can severely limit sunflower (Helianthus annuus L.) grain yield and quality. Our objective was to evaluate N diagnosis methods based on: (a) pre-plant soil nitrate-nitrogen (NO3––N) test (PPSNT) and ...

    • Cover crop species can increase or decrease the fertilizer-nitrogen requirement in maize 

      Carciochi, Walter Daniel; Massigoge, Ignacio; Lapaz Olveira, A.; Reussi Calvo, Nahuel Ignacio; Cafaro La Menza, Francisco; Sainz Rozas, Hernan Rene; Barbieri, Pablo; Di Napoli, M.; Gonzalez Montaner, J.; Ciampitti, Ignacio A. (American Society of Agronomy; Estados Unidos, 2021-07-03)
      Cover crop species and termination date could affect fertilizer-N management and N diagnostic methods traditionally used in bare fallow-maize (Zea mays L.) systems. Our objectives were to (a) assess the impact of cover ...

    • Nitrogen and sulfur interaction on nutrient use efficiencies and diagnostic tools in maize 

      Carciochi, Walter Daniel; Salvagiotti, Fernando; Pagani, Agustin; Reussi Calvo, Nahuel Ignacio; Eyherabide, Mercedes; Sainz Rozas, Hernan Rene; Ciampitti, Ignacio A. (Elsevier, 2020-05)
      Nitrogen (N) and sulfur (S) critical dilution curves and the N:S stoichiometry are useful tools for evaluating nutrient status in maize (Zea mays L.). Nutrient supply for both N and S impact plant nutrient uptake, consequently ...

    • Predicting soil test phosphorus decrease in non-P-fertilized conditions 

      Appelhans, Stefania Carolina; Carciochi, Walter Daniel; Correndo, Adrián A.; Gutierrez Boem, Flavio Hernán; Salvagiotti, Fernando; García, Fernando O.; Melchiori, Ricardo Jose; Barbagelata, Pedro Anibal; Ventimiglia, Luis Alberto; Ferraris, Gustavo Nestor; Vivas, Hugo Silverio; Caviglia, Octavio; Ciampitti, Ignacio A. (Wiley, 2020-02)
      Monitoring the availability of phosphorus (P) in soil under continuous cropping facilitates finding deficiency in crops and contributes to improving crop growth and nutrient management models. Soil P availability for crops ...
