Addition of amendments to restore a compacted soil under no-tillage system
(Universidade Estadual de Maringá, 2023-04)The addition of organic and inorganic amendments can improve soil structure and reduce soil compaction. In this context, this study aimed to evaluate whether the application of amendments reduces penetration resistance ... -
Addition of organic and inorganic amendments to regenerate the surface structure of silty soils
(Wiley, 2019-11-30)The widespread degradation of the structure of silty soils under no till systems (NT) that has been observed in recent years is characterized by the presence of a platy structure (P) near the soil surface. Under these ... -
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 ... -
Caracterización de la cuenca del Arroyo Estacas y relación con el uso del suelo y la morfología del cauce
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Entre Ríos, 2019)La caracterización morfométrica de una cuenca es una etapa inicial de la modelación de la dinámica hídrica y procesos erosivos asociados. Los objetivos del trabajo fueron caracterizar la cuenca del Arroyo Estacas y su cauce ... -
Cover crop benefit bacteria and increase aggregate-associate soil C and N storage
(Elsevier, 2024-03)The aim of this study was to analyze the effect of four crop sequences with different aboveground biomass and crop residue biochemical composition on biological soil variables, fractions of soil organic matter, and soil ... -
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: ... -
Diversified crop sequences to reduce soil nitrogen mining in agroecosystems
(Elsevier, 2022-10)Nitrogen (N) is the primary driver of increased global food supply, but has environmental consequences from both under- and over-fertilisation. While over-fertilisation and reactive nitrogen release onto the environment ... -
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. ... -
Driving factors of tree biomass and soil carbon pool in xerophytic forests of northeastern Argentina
(Springer, 2023-12)Background: The conversion of forests into agricultural lands can be a threat because the forests carbon stored could be a source of emissions. The capacity to improve the predictions on the consequences of land use change ... -
Escurrimiento y coeficientes de enriquecimiento en sedimentos erosionados bajo diferentes secuencias agrícolas
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Entre Ríos, 2022)En las últimas décadas la producción agrícola en la región pampeana se ha asociado con la degradación del recurso suelo, dada por la disminución del contenido de materia orgánica, pérdida de estructura, compactación y ... -
Escurrimiento y producción de sedimentos en una pequeña cuenca agrícola aforada de Entre Ríos, Argentina : aplicación del Modelo WEPP
(Asociación Argentina Ciencia del Suelo, 2018-07)La erosión del suelo es un problema ampliamente reconocido. sin embargo, resulta muy difícil evaluar de manera fiable y precisa la magnitud y la tasa del proceso a nivel de lote y de cuenca. el modelo Water erosion Prediction ... -
Impact of crop aerial and root biomass inputs on soil nitrifiers and cellulolytic microorganisms
(Elsevier, 2019)In agricultural no-till systems, crop residue management has an important impact on the activity and abundance of soil microorganisms, which play a crucial role in soil health and quality. In these systems, when cover crops ... -
Índice agroambiental para la evaluación del impacto por cambio de uso del suelo a nivel predial en agroecosistemas del Espinal entrerriano
(Universidad de Buenos Aires, 2017)El objetivo fue desarrollar un índice agroambiental (IAG) integrando indicadores de calidad de suelo (ICS) y vegetación (ICV) para evaluar el impacto por cambio de uso del suelo en áreas de bosques nativos, a nivel predial, ... -
Nitrous oxide emission after the addition of organic residues on soil surface
(Elsevier, 2017)The addition of organic amendments with a low Carbon:Nitrogen (C:N) ratio to restore degraded soils may increase the emission of greenhouse gases and affect the storage of these elements in the topsoil. Our objectives were ... -
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 ... -
Relación cartográfica entre variables hidrológicas y de degradación por pérdida de suelo superficial: sitio piloto A° Estacas, Entre Ríos
(Asociación Argentina de la Ciencia del Suelo, 2022-12)El aumento del área agrícola en el norte de la provincia de Entre Ríos resulta de la pérdida del bosque nativo. Este cambio del uso del suelo impacta los servicios ecosistémicos que brindan las cuencas hidrográficas, e ... -
Soil quality impacts of current South American agricultural practices
(Society for Urban Ecology, 2015)Increasing global demand for oil seeds and cereals during the past 50 years has caused an expansion in the cultivated areas and resulted in major soil management and crop production changes throughout Bolivia, Paraguay, ...
