Assessing soil P fractions changes with long‐term phosphorus fertilization related to crop yield of soybean and maize
(Wiley, 2020-02)Long-term P fertilization increases soil phosphorus (P) labile fractions, which can be associated with crop P uptake and grain yield and are useful to improve fertilizer recommendations. Research aims were to evaluate in ... -
Crop sequence and P fertilization effects on soil P fractions under no-tillage
(Springer, 2021-05-27)Increasing cropping intensity may affect phosphorus (P) recycling through crop residue inputs, which may differ in soils with different productivity, P adsorption capacity, and P fertilization level. In three crop sequences: ... -
Does the fertilisation strategy affect the long-term legacy phosphorus dynamic?
(Elsevier, 2024-02)Phosphorus (P) imbalances in agricultural systems are a global problem because they have environmental and economic impacts, like eutrophication when there is a soil P surplus and low crop productivity in P deficient soils. ... -
Efecto del agregado de fósforo y nitrógeno en el crecimiento de cultivos de alfalfa en rebrotes de primavera y verano en un suelo vertisol de Entre Ríos
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-04)Se analizó el efecto de P y N sobre la acumulación de biomasa (AB) primavero-estival (pri06–ver07) de alfalfa (grado de reposo 6) en un suelo vertisol en la provincia de Entre Ríos. En un diseño en bloques completos al ... -
Eficiencia agronómica de fósforo: efecto de fuentes líquidas y sólidas en suelos con presencia de calcáreo de Entre Ríos
(Escuela para Graduados Ing. Agr. Alberto Soriano, Facultad de Agronomía, Universidad de Buenos Aires, 2013-06)La respuesta a la fertilización fosfatada es generalizada en la región pampeana argentina. Los fertilizantes, al ser aplicados al suelo, se disuelven y reaccionan con constituyentes del suelo y con compuestos del ... -
Predicting soil test phosphorus decrease in non-P-fertilized conditions
(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 ... -
Respuesta del rendimiento del maíz a fósforo, azufre y zinc en la provincia de Entre Ríos, Argentina
(Asociación de Ingenieros Agrónomos del Norte de la Provincia de Buenos Aires, 2022-11)The nutrients that mainly condition the yields of extensive crops in Argentina are nitrogen and phosphorus, but the lack of replenishment and continuous agricultural activity have produced a decrease in the availability ... -
Sediment and nutrient deposition in different riparian forests and floods of the Middle Paraná River
(Wiley, 2019-10)Sedimentation processes are important to the dynamics of lowland fluvial systems and depend on the characteristics of floods and of riparian ecosystems. The few known studies for the Paraná River system analyzed only summer ...
