An efficiently biological nitrogen fixation of non-native Lotus tenuis justifies its key role in the flooding Pampas (Argentina)
(Elsevier, 2025-01)Forage production is a major challenge in the Salado River basin, Argentina (also denominated “Flooding Pampas”), the largest livestock raising area. The successful naturalization of the European legume Lotus tenuis (native ... -
Exploring Phosphate Solubilizing Bacterial Communities in Rhizospheres of Native and Exotic Forage Grasses in Alkaline‑Sodic Soils of the Flooding Pampa
(Springer, 2024-05-25)The fooding pampa is one of the most important cattle-raising regions in Argentina. In this region, natural pastures are dominated by low-productivity native grass species, which are the main feed for livestock. In this ... -
First-year cover crop effects on the physical and hydraulic properties of the surface layer in a loamy soil
(Elsevier, 2021-09)Soil degradation is a global problem, threating its conservation and affecting agronomic production. No-tillage (NT) is the main management system for soil conservation world-wide. However, in Argentina, simplification of ... -
Short-term effects of cover crop inclusion under no-tillage management on soil physical quality = Efectos de corto plazo de la inclusión de un cultivo de cobertura bajo siembra directa sobre la calidad física del suelo
(Asociación Argentina de la Ciencia del Suelo, 2021-12)Integrating cover crops (CC) in the crop sequence could lead to an enhancement of the notillage (NT) performance improving soil physical quality (SPQ). The objectives of this work were: i- to determine the SPQ on different ... -
Caracterización fisicoquímica y microbiológica del biopreparado “supermagro”. Efectos de su aplicación precosecha en parámetros de calidad de frutilla
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2023-12)El objetivo del presente trabajo fue caracterizar fisicoquímica y microbiológicamente el biopreparado “Supermagro” (SM), elaborado por productores/as agroecológicos/as, y estudiar el efecto de su aplicación precosecha en ... -
Age at first gestation in bovine influences female progeny post-weaning growth and reproductive development
(Elsevier, 2024-12)This study investigated the impact of the age at which heifers conceive for the first time on the growth and reproductive development of their female offspring. A total of seven heifers pregnant at 15 months of age (15M), ... -
Oro-ruminal sampling device and technique for rapid collection of rumen content and improved recovery of solid fractions for microbiome analysis
(Elsevier, 2024-05)Rumen fistulation is a widely used procedure that allows for collection of ruminal contents. However, fistulation is an invasive and costly procedure that generally limits the number of animals that can be recruited for ... -
Lotus spp.: a Mediterranean genus with high environment and economic impact in the Salado River Basin (Argentina)
(Springer, 2024-05)This review has the principal objective in to hypothesise that the introduction of Lotus species could have significant benefits in constrained soils due their worldwide distribution. This idea is major based on results ... -
Impact of dairy farms on groundwater quality in a productive basin in the northeast of the Pampean Plain, Argentina
(Elsevier, 2023-11)The Pampean Plain is a relevant world food production area where livestock and agricultural activities are developed. The northeast of this region is characterized by dairy production, where large quantities of excreta ... -
The degree of maternal nutrient restriction during late gestation influences the growth and endocrine profiles of offspring from beef cows
(CSIRO, 2021)Context: Cow–calf operations in Argentina are managed under extensive grazing condition and the quality of forages is often poor during the second half of gestation. The severity of nutrient restriction in bovine gestation, ... -
The Effects of Age at Weaning and Length of Lipid Supplementation on Growth, Metabolites, and Marbling of Young Steers
(MDPI, 2020-10)The objective of this study was to determine how weaning age, days on supplements, and lipid supplementation affected the growth and marbling deposition of steers. Steers from a single sire were early weaned (n = 24) at ... -
Enyesado de suelos sódicos: modificación de sus propiedades químicas, físicas y biológicas
(Facultad de Agronomía, Universidad Nacional de La Plata, 2021-12)Los suelos sódicos ocupan una extensa proporción de la Depresión del Salado. El sodio aumenta el pH y provoca la dispersión de las arcillas generando modificaciones en la estructura de los suelos que perjudican el crecimiento ... -
Soil water availability and water absorption by maize in sodic soils with high water table
(Elsevier, 2023-05)Context: Because of the increasing prices of commodities over the last decades, crops like maize (Zea mays L.) are being cultivated in lowland sodic soils with physical-chemical constraints, such as those having natric ... -
Comparison of the 7-day CO-Synch and 8-day estradiol-based protocols for estrus synchronization and timed artificial insemination in suckled Bos taurus cows
(Elsevier, 2023-04)Two experiments were conducted to compare, follicle diameter (FD) on Day −1, corpus luteum (CL) area on Day 7, progesterone (P4) concentration on Day 7 and 18, pregnancy per timed artificial insemination (TAI) on Day 30, ... -
Cation nutrient reserves decline markedly under intensive cropping of Pampas Mollisols
(Elsevier, 2023-04)The availability of exchangeable cationic nutrients in soils, such as calcium (Cae), magnesium (Mge), and potassium (Ke), is vital for crops growth and development. However, the concentration of these nutrients can be ... -
