Impacto en los flujos hídricos por la presencia de horizontes petrocálcicos en parcelas forestadas en ambientes de llanura
(Ediciones INTA, 2019-12)Alrededor del mundo existen numerosos paisajes con presencia de horizontes petrocálcicos, como en el caso de la llanura Pampeana en Sudamérica. En muchos casos, estos horizontes constituyen una barrera física al flujo de ... -
Improve intra‐uterine insemination in rabbits using ultra‐high temperature skim milk as extender to keep semen at room temperature
(Wiley, 2016-03)Two experiments were carried out to examine in vitro quality and in vivo fertility of rabbit semen diluted in ultra‐high temperature (UHT) skim milk. In the first experiment, pooled ejaculates of 10 adult rabbits were ... -
Improving concentration of healthy fatty acids in milk, cheese and yogurt by adding a blend of soybean and fish oils to the ration of confined dairy cows
(2020-01-18)Compared to pasture based sistems, milk produced in confined dairy systems is characterized by a high saturated fat (SF) content with a lower concentration of healthy fatty acids (FA) such as vaccenic (VA, trans-11C18:1), ... -
Improving the Quality of Milk Fatty Acid in Dairy Cows Supplemented with Soybean Oil and DHA-Micro Algae in a Confined Production System
(2018-09-10)The objective was to reduce saturated fatty acids (SFA) and increase conjugated linoleic acid (CLA, cis- 9, trans -11 C18:2), α-linolenic (cis- 9, cis- 12, cis- 15 C18:3) and docosahexaenoic (DHA, C22:6) contents in milk ... -
Improving Yield and Quality of Processing Potato Crops Grown in the Argentinian Pampas: the Role of N, P and S and Their Impact on CO2 Emissions
(Springer Netherlands, 2018-03-17)The area grown with processing potato crops in the Argentinian Pampas has been increasing steadily since 1995. The aim of this work was to assess the effects of N, P and S upon yield and tuber quality and their impact on ... -

Inclusion of cover crops in cropping sequences with soybean predominance in the southeast of the Humid Argentine Pampa
(2013)The incorporation of a cover crop (CC) may be an alternative to increase soil carbon (C) and nitrogen (N) supply in crop sequences with a high frequency of soybean. The aims of this study were (i) to determine shoot biomass ... -
Incorporación de cultivos de cobertura previos a soja en el sudeste bonaerense
(2013-06)En la zona del sudeste bonaerense existe escasa información sobre las eventuales ventajas de la incorporación de los CC en los planteos productivos actuales, la cual sería de suma utilidad para evaluar la factibilidad de ... -
