Soil organic carbon changes simulated with the AMG model in a high-organic-matter Mollisol
(Sociedad Española de la Ciencia del Suelo, 2016)Soil organic carbon (SOC) management requires a precise knowledge of how it is affected by soil use. Simulation models could help for this purpose. The AMG model is simple, requires information that is easily available, ... -
Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
(Wiley, 2020-01)Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ... -
Sorghum biomass yield and allocation as affected by the combination of photoperiod sensitivity, sweet-stalk and brown midrib traits
(Elsevier, 2024-01)Context or problem: Traits like photoperiod sensitivity, sweet-stalk and brown midrib (bmr) have been introgressed to increase the biomass yield and quality of sorghum (Sorghum bicolor (L.) Moench) towards bioenergy yield ... -
Soybean and wheat response to lime in no-till Argentinean mollisols
(Elsevier, 2015-09)Crop production in Argentina has significantly increased over the past few years; this increase was consequence of better management practices which included P and N fertilization and, occasionally, S fertilization. Commonly ... -
Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(2016-02-01)It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ... -
Spatial and temporal variation in the migration of Ruddy-headed Goose in southern South America using satellite tagging
(Cambridge University Press, 2020-04-30)Ruddy-headed Goose Chloephaga rubidiceps is the smallest of the five South American sheldgeese and has two separate populations: one sedentary, which resides in the Malvinas/Falkland Islands and one migratory that overwinters ... -
Spatial–temporal trends and economic losses associated with bovine abortifacients in central Argentina
(Springer, 2022-07-30)The aims of this work are, firstly, to provide the geolocalization of cases of bovine abortion with definitive diagnosis and, secondly, to estimate the economic losses due to the most frequent abortifacients diagnosed ... -
Spike architecture traits associated with type II resistance to fusarium head blight in bread wheat
(Springer, 2021-11-05)Fusarium head blight (FHB) remains a devastating disease in bread wheat (Triticum aestivum L.). Genetic resistance to FHB is complex; aside from active physiological resistance, plant developmental and morphological traits ... -
Spongy Myelinopathy in Newborn Beef Calves Associated with Consumption of Corn Infected with Stenocarpella maydis
(Elsevier, 2019-10)Stillbirth and perinatal mortality with neurological signs and lesions were diagnosed in two calves following ingestion by their dams of corn infected with Stenocarpella maydis during the third trimester of gestation. ... -
Spontaneous outbreak of Pascalia glauca poisoning in sheep in Argentina
(Brazilian Association of Veterinary Pathology, 2021-04-22)Pascalia glauca is a native weed and one of the most common hepatotoxic plant affecting cattle in Argentina. Although experimental P. glauca poisoning have been reported in sheep, no spontaneous cases have been reported ... -
Stand density management diagrams of Eucalyptus Viminalis: predicting stem volume, biomass and canopy cover for different production purposes
(Universidade Federal de Lavras, 2019-12-13)Stand density management diagrams (SDMD) provide a guide for forest density management taking into account stands attributes such as trees´ diameter or volume. One of the most common species planted in Pampean plains of ... -
Standard methods for fungal brood disease research = Métodos estándar para la investigación de enfermedades fúngicas de la cría
(Taylor & Francis, 2013)Chalkbrood and stonebrood are two fungal diseases associated with honey bee brood. Chalkbrood, caused by Ascosphaera apis, is a common and widespread disease that can result in severe reduction of emerging worker bees and ... -
Storage of WDGS under hermetic and non-hermetic conditions : effect on sensory properties, microorganisms, mycotoxins and nutritional value.
(Elsevier, 2019-01)WDGS production in Argentina substantially increased in the last 5 years and become a frequent constituent for feed diets. However, due to the extremely high moisture content of the product, quality deterioration occurs ... -
Storing soybeans (Glycine max) in silo bags: economic outcomes and grain loss risk
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2020-12-01)Silo bags have the potential to increase grain marketing efficiency and to give farmers additional bargaining power. However, silo bags are prone to tearing that can cause grain losses. This article assesses the economic ... -
Stover biogas potential of corn crops grown under contrasting water availability and nitrogen supply
(Elsevier, 2020-12-31)Corn stover is a biogas feedstock capable of enhancing agriculture bioenergy potential. Although the influence of growing conditions on biogas yield of corn stover has been reported, the joint effects of water and nitrogen ... -
Strategic use of honey bees (Apis mellifera L.) to increase the number and size of fruits in kiwifruit (Actinidia chinensis var. deliciosa)
(Elsevier, 2022-02)Fruit size in kiwifruit depends mainly on the number of seeds or fertilized ovules. Pollination by wind is not enough to obtain a fruit size accepted by the market, so it is necessary to perform this practice by means of ... -
