Assessment of the main factors affecting the dynamics of nutrients in two rainfed cereal watersheds
Nutrient dynamics and factors that control nutrient exports were observed in two watersheds, namely Latxaga and La Tejería, with similar climatic and management characteristics throughout 10 years (2007–2016). Similar ... -
Both free indole-3-acetic acid and photosynthetic performance are important players in the response of Medicago truncatula to urea and ammonium nutrition under axenic conditions
We aimed to identify the early stress response and plant performance of Medicago truncatula growing in axenic medium with ammonium or urea as the sole source of nitrogen, with respect to nitrate-based nutrition. Biomass ... -
Can ammonium stress be positive for plant performance?
In this article, we propose a change of paradigm where ammonium nutrition may be considered not exclusively as an undesirable situation for plant performance, but as a way to provoke changes in plant metabolism that can ... -
Efectos inmediatos y a corto plazo de una quema prescrita en las propiedades de un suelo de montaña atlántica
(2019) Trabajo Fin de Máster/Master Amaierako LanaLa matorralización de los pastos de montaña es una problemática actual que deriva en la pérdida de paisajes abiertos, disminución de biodiversidad y aumento de riesgo de incendios en espacios naturales. ... -
Estudio de los efectos inmediatos de una quema prescrita en un pasto matorralizado del Pirineo Navarro sobre el ciclo del nitrógeno edáfico
(2019) Trabajo Fin de Grado/Gradu Amaierako LanaAnte el cambio global (cambio climático, despoblación rural, cambio en los sistemas productivos...) los pastos de montaña están sufriendo un proceso de matorralización que conlleva una ... -
Estudio del potencial antioxidante en hortalizas asociado a la práctica de fertilización nitrogenada
(2022) Trabajo Fin de Grado/Gradu Amaierako LanaLa fertilización nitrogenada basada en nitrato genera la acumulación de antinutrientes, nitrato y oxalato, en las hojas de hortalizas que al ser ingeridas perjudica nuestra salud. En contraposición, estas hortalizas presentan ... -
Estudio del valor fertilizante de té de compost de distintos grados de madurez en relación a fertilizantes minerales para el cultivo de espinaca
(2023) Trabajo Fin de Máster/Master Amaierako LanaLa Comisión Europea impulsa desde 2014 la idea de transitar hacia un modelo económico circular. El compostaje de biorresiduos y el uso de compost reducen algunos de los impactos negativos ocasionados por la generación y ... -
Evaluation of nitrate soil probes
La producción y utilización de los fertilizantes químicos de N han desempeñado un gran papel en el aumento del rendimiento de los cultivos y en la satisfacción de la demanda del crecimiento de la población. El nitrato ... -
Evaluation of nitrate soil probes for a more sustainable agriculture
Synthetic nitrogen (N) fertilizers and their increased production and utilization have played a great role in increasing crop yield and in meeting the food demands resulting from population growth. Nitrate (NO3−) is the ... -
Evolution and assessment of a nitrate vulnerable zone over 20 years: Gallocanta groundwater body (Spain)
Nitrate pollution from agricultural sources is one of the biggest issues facing groundwater management in the European Union (EU). During the last three decades, tens of nitrate vulnerable zones (NVZ) have been designated ... -
IAOx induces the SUR phenotype and differential signalling from IAA under different types of nitrogen nutrition in Medicago truncatula roots
Indole-3-acetaldoxime (IAOx) is a particularly relevant molecule as an intermediate in the pathway for tryptophan-dependent auxin biosynthesis. The role of IAOx in growth-signalling and root phenotype is poorly studied in ... -
Leaves play a central role in the adaptation of nitrogen and sulfur metabolism to ammonium nutrition in oilseed rape (Brassica napus)
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 ... -
Optimización de nutrición nitrogenada en hortícolas de hoja crecidas en sistema de hidroponía pura NGS*: ajustes de nutrición mineral a lo largo del ciclo de producción
(2022) Trabajo Fin de Grado/Gradu Amaierako LanaLa fertilización nítrica provoca altos niveles de nitrato en hortalizas de hoja. A nivel internacional se ha sugerido que su consumo sea la parte mayoritaria de nuestras dietas, pero la elevada exposición a nitratos puede ... -
A plant gene encoding one-heme and two-heme hemoglobins with extreme reactivities toward diatomic gases and nitrite
In plants, symbiotic hemoglobins act as carriers and buffers of O2 in nodules, whereas nonsymbiotic hemoglobins or phytoglobins (Glbs) are ubiquitous in tissues and may perform multiple, but still poorly defined, functions ... -
Quantitative proteomics reveals the importance of nitrogen source to control glucosinolate metabolism in Arabidopsis thaliana and Brassica oleracea
Accessing different nitrogen (N) sources involves a profound adaptation of plant metabolism. In this study, a quantitative proteomic approach was used to further understand how the model plant Arabidopsis thaliana adjusts ... -
Runoff, nutrients, sediment and salt yields in an irrigated watershed in southern Navarre (Spain)
The environmental impact of irrigated agriculture on water quality was assessed in Landazuria watershed (Navarre, northeast Spain), a 479.5 ha watershed with 53% of irrigated agricultural land. In the framework of a long-term ... -
Soil moisture modulates biological nitrification inhibitors release in sorghum plants
Background and aims: Sorghum (Sorghum bicolor) is able to exude allelochemicals with biological nitrifcation inhibition (BNI) capacity. Therefore, sorghum might be an option as cover crop since its BNI ability may reduce ... -
Unraveling nitrate-mediated mechanisms in response to ammonium toxicity in plants
(2022) Tesis doctoral / Doktoretza tesiaIntensive use of nitrate in agriculture has resulted in serious environmental and health problems; however, using ammonium as an exclusive, alternative nitrogen source can have deleterious effects on plant growth. Even at ... -
Utilización del ion cloruro en hortalizas de hoja para minimizar su contenido en nitrato
(2021) Trabajo Fin de Máster/Master Amaierako LanaEl nitrógeno es un nutriente esencial para las plantas de limitada disponibilidad en el suelo para ser absorbido por las raíces. Por tanto, su aplicación como fertilizante es fundamental para la agricultura actual. El ...
