    • Depletion of the heaviest stable N isotope is associated with NH4+/NH3 toxicity in NH4+-fed plants 

      Ariz, Idoia Upna; Cruz, Cristina; Morán Juez, José Fernando Upna; González Moro, María B.; García Olaverri, Carmen Upna; González Murua, Carmen; Martins Loucao, María A.; Aparicio Tejo, Pedro María Upna (BioMed Central, 2011)   Artículo / Artikulua  OpenAccess
      Background: In plants, nitrate (NO3-) nutrition gives rise to a natural N isotopic signature (δ15N), which correlates with the δ15N of the N source. However, little is known about the relationship between the δ15N of the ...
    • Effect of feeding regime on composting in bins 

      Storino, Francesco Upna; Menéndez Villanueva, Sergio Upna; Muro Erreguerena, Julio Upna; Aparicio Tejo, Pedro María Upna; Irigoyen Iriarte, Ignacio Upna (Taylor & Francis, 2017)   Artículo / Artikulua  OpenAccess
      Composting in bins is one of the most practical home composting methods. There is currently a need for greater information to improve the management of the composting process and to create home composting programs, which ...
    • From ground pollution to soil fertilization: an environmental assessment of soil amendments derived from organic wastes 

      Calleja Cervantes, María Eréndira Upna (2015)   Tesis doctoral / Doktoretza tesia  OpenAccess
      El crecimiento de la población y sus necesidades de alimentación en las últimas décadas han sido mayoritariamente sustentados por un modelo productivo lineal a escala global basado en consumir recursos y generar residuos. ...
    • Isotopic composition of maize as related to N-fertilization and irrigation in the Mediterranean region 

      Lasa Larrea, Berta; Irañeta, Iosu; Muro Erreguerena, Julio Upna; Irigoyen Iriarte, Ignacio Upna; Aparicio Tejo, Pedro María Upna (Escola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, 2011)   Artículo / Artikulua  OpenAccess
      Nitrate leaching as a result of excessive application of N-fertilizers and water use is a major problem of vulnerable regions. The farming of maize requires high N fertilization and water inputs in Spain. Isotopic ...
    • Leaf δ15N as a physiological indicator of the responsiveness of N2-fixing alfalfa plants to elevated CO2, temperature and low water availability 

      Ariz, Idoia Upna; Cruz, Cristina; Neves, Tomé; Irigoyen, Juan J.; García Olaverri, Carmen Upna; Nogués, Salvador; Aparicio Tejo, Pedro María Upna; Aranjuelo Michelena, Iker (Frontiers Media, 2015)   Artículo / Artikulua  OpenAccess
      The natural 15N/14N isotope composition (δ15N) of a tissue is a consequence of its N source and N physiological mechanisms in response to the environment. It could potentially be used as a tracer of N metabolism in plants ...
    • Leaves play a central role in the adaptation of nitrogen and sulfur metabolism to ammonium nutrition in oilseed rape (Brassica napus) 

      Coleto, Inmaculada; Peña, Marlon de la; Rodríguez Escalante, Jon; Bejarano, Iraide; Glauser, Gaëtan; Aparicio Tejo, Pedro María Upna; González Moro, María B.; Marino Bilbao, Daniel Upna (BioMed Central, 2017)   Artículo / Artikulua  OpenAccess
      Background: The coordination between nitrogen (N) and sulfur (S) assimilation is required to suitably provide plants with organic compounds essential for their development and growth. The N source induces the adaptation of ...
    • Meat waste as feedstock for home composting: effects on the process and quality of compost 

      Storino, Francesco Upna; Sánchez Arizmendiarrieta, Joseba; Irigoyen Iriarte, Ignacio Upna; Muro Erreguerena, Julio Upna; Aparicio Tejo, Pedro María Upna (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
