Changes in soil phosphorus (P) fractions and P bioavailability after 10 years of continuous P fertilization
(Elsevier, 2023-08)Phosphorus fertilization modify soil P fractions differing in availability, but little is known about bioavailability of these pools for the crops when increasing P fertilizer rates in the medium term. Our objectives were ... -
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). ... -
DTPA-extractable zinc threshold for wheat grain yield response to zinc fertilization in Mollisols
(Wiley, 2021-06)Determining soil Zn thresholds for wheat (Triticum aestivum L.) is still challenging since soil Zn tests have been poorly calibrated. Therefore, this work aimed to determine, under field conditions, the DTPA-Zn critical ... -
Maize nitrogen management in soils with influencing water tables within optimum depth
(Wiley, 2020-10)The central temperate Argentinean region is currently affected by rising water tables, allowing higher and more stable maize yields (Zea mays L) when they fluctuate within optimum depth. However, limited information was ... -
Nutritional and environmental effects on biological nitrogen fixation in soybean: a meta-analysis
(Elsevier, 2019-07)Biological N2 fixation (BNF) and mineral soil absorption are complementary N sources for soybean growth. BNF is sensitive to nutrient and environmental conditions, though a comprehensive synthesis of the studies underlying ... -
Plant stand, nodulation and seed yield in soybean as affected by phosphate fertilizer placement, source and application method
(2013-11)Establishing an optimum plant population at planting is the start-point for assuring seed yield in crops. In addition to plant establishment, the onset of a fully functional nodule system is crucial for nitrogen nutrition ... -
Soja de alto rendimiento: ganancia genética y limitación por nitrógeno
(IPNI, 2017-12)La mejora genética del rendimiento de soja desde la década de 1980 hasta la del 2010 representó 30% promediando en sitios ubicados en los Estados Unidos y Argentina. Para todas las pocas de liberación, la fertilización ...
