Anaerobically incubated nitrogen improved nitrogen diagnosis in corn
(2017)Current N diagnostic methods for corn (Zea mays L.) are often based on the nitrate nitrogen (NO3 ––N) concentration before planting (pre-plant nitrate test, PPNT) and nitrate nitrogen (NO3––N) concentration at V6 stage ... -
Contribución de la fijación biológica de nitrógeno en vicia y arveja
(EEA Oliveros, INTA, 2020)En Argentina el cultivo de soja (Glycine max L) predomina en los sistemas agrícolas, en la mayor parte de los casos como monocultivo (Caviglia y Andrade, 2010) y con largos periodos de barbecho descubierto, poniendo en ... -
Contribution of different sources and origins of nitrogen in above- and below-ground structures to the partial nitrogen balance in soybean
(Springer, 2022-04)Aims: Most studies that quantified the biological N fixation (BNF) and partial N balances of soybean have ignored the belowground structures. Our objectives were to evaluate the contribution of belowground structures to ... -
Does biological nitrogen fixation modify soybean nitrogen dilution curves?
(2018)Biological nitrogen fixation (BNF) in soybean [Glycine max (L.) Merr.] represents, on average, 60% of total nitrogen (N) uptake. Nitrogen dilution curves link aboveground crop N concentration (%N) to biomass accumulation (W). ... -
Efecto de dosis variables de nitrógeno sobre el rendimiento y calidad de trigo
(EEA Reconquista, 2017-12)La elección y siembra de variedades de mayor calidad panadera, no asegura por sí misma un mayor contenido de proteínas en grano. -
Eficiencia de uso de nitrógeno en cebada en el sudeste bonaerense : efecto de aplicaciones divididas = Nitrogen use efficiency of barley in the southeastern Buenos Aires: effect of split applications
(2015-06)El nitrógeno (N) es el principal nutriente que limita el rendimiento y la calidad industrial de cebada (Hordeum vuggare L). El fraccionamiento del N en ambientes húmedos, permitiría maximizar la eficiencia de uso de N ... -
Eficiencia de uso del nitrógeno por forrajeras abonadas con estiércol de bovinos lecheros en la región pampeana, Argentina
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-07)La intensificación de los sistemas ganaderos con el consiguiente aumento de la carga animal incrementa la cantidad de estiércol que puede ser reutilizado como una fuente de nutrientes para cultivos forrajeros. El propósito ... -
Eficiencia en el uso del nitrógeno en vacas lecheras y su impacto en el ambiente
(Facultad de Ciencias Veterinarias, Universidad Nacional del Centro de la Provincia de Buenos Aires, 2020)El productor agropecuario se enfrenta al desafío de mejorar la eficiencia de uso de los recursos disponibles y, al mismo tiempo, reducir la contaminación ambiental. La producción animal representa una fuente significativa ... -
Estimating nitrogen, phosphorus, potassium, and sulfur uptake and requirement in soybean
(Elsevier, 2021-07)Estimation of crop nutrient demand, seed nutrient removal, and nutrient use efficiency (yield to nutrient uptake ratio) are crucial for pursuing both balanced nutrition and more sustainable farming systems. However, the ... -
Exploring nitrogen limitation for historical and modern soybean genotypes
(American Society of Agronomy, 2018-10)The United States (USA) and Argentina (ARG) account for over 50% of the global soybean [Glycine max (L.) Merr.] production. Soybean N demand is partially met (50–60%) by the biological nitrogen fixation (BNF) process; ... -
Identifying sulfur deficient fields by using sulfur content; N:S ratio and nutrient stoichiometric relationships in soybean seeds
(2012-08)Sulfur (S) fertilization has increasingly become an important issue in crop management. In Argentina S deficiencies have been reported, but there has been no success in finding soil tests for predicting soybean response ... -
N:P:S stoichiometry in grains and physiological attributes associated with grain yield in maize as affected by phosphorus and sulfur nutrition
(2017-03)Balanced nutrition is necessary to reduce yield gaps in maize. Simultaneous phosphorus (P) and sulfur (S) deficiencies may be present in soils, so a P × S interaction is expected. In maize, yield is closely related to grain ... -
New insights into soybean biological nitrogen fixation
(American Society of Agronomy, 2018-08)Soybean biological N2 fixation (BNF) relationships with fertilizer N and yield response have been comprehensively reviewed in the scientific literature. However, the study of the N-gap between N uptake and N supplied by ... -
Nitrogen and sulfur interaction on nutrient use efficiencies and diagnostic tools in maize
(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 ... -
Nitrogen balance in a plant-soil system under different cover crop-soybean cropping in Argentina
(2018-10-10)Cover crops (CC) provide many benefits for the soil and the following crop but their effects on nitrogen (N) release and balance in continuous no-tillage soybean (Glycine max L. Merr.) production are little known. Estimation ... -
Nutrient partitioning and stoichiometry in soybean: A synthesis-analysis
(2017-01)On-farm attainable soybean yields are primarily limited by nutrient and water supply. High-yielding soybeans is related to high nutrient uptake. A proposed theoretical framework underpinning yield formation includes plant ... -
Relative importance of biological nitrogen fixation and mineral uptake in high yielding soybean cultivars
(2017-09)Backgrounds and aims: Soybean yield depends on total N uptake, N use efficiency, and harvest index. Nitrogen uptake relays on biological fixation (BNF) and soil absorption. Usually, BNF is considered a yield-related process. ... -
