ABSTRACT.- Hostipastoral systems in small farming units that integrate horticulture crops, as main cash crop, with sheep/cattle raising on cultivated forage, in Uruguay, present physical restrains to crops because of high consistency and compaction of the vertic soils and unique tillage requirements. The objective of this study was to evaluate the effect of different hortipastoral systems on soil organic matter, aggregation, porosity, permeability and onion yield during a cropping year in onion-forage hortipastoral systems. A long-term experiment was installed in 1995 in the National Institute for Agricultural Research (INIA-Las Brujas) in Uruguay, on fine (mixed) smectitic thermic superactive Vertic Argiudolls. The soil was previously under native grasslands, and treatments consisted of cropping systems for onion (Allium cepa L.) production, maintained for three years and then rotated. Onion yield was evaluated during the period 1998?2006, and in the cropping year 2006?2007, corresponding to the end of a 3-year cropping cycle, we evaluated soil organic matter and physical properties and functioning in the cropping systems: alfalfa, fescue, forage consortium (birdfoot trefoil, alfalfa and white clover), onion after alfalfa, onion after fescue, and onion after consortium. At four times during the cropping year, aggregate stability and organic matter were determined for the 0?0.05 m soil layer, whereas soil bulk density, porosity, and hydraulic conductivity were determined in 0?0.10 and 0.10?0.20 m layers. The results showed high variability in onion yields from 1998 to 2006 (10.8?36.4 Mg ha 1), mainly related to high rainfall (higher than 150 mm) that affected crop planting, and the low rainfall (lower than 30 mm) that affected growth and development. In two out of eight years, there were significant differences in onion yield among treatments, where alfalfa (1999) and fescue (2006) crops are more beneficial to onion yield than pasture consortium. To establish the onion crop in the vertic soil tillage is needed, but tilling the soil under forage crops reduces macro and increases microaggregation (reduces GMDw from 1.8 to 0.8 mm), increases macroporosity (close 0.07 to 0.25 m3 m 3) and functioning in terms of water and air permeability (Ka increase above 3 μm2 after tillage) and decreases the degree of compaction (under forages decreased DC from 69-84% to 58?60% in surface layer). In conclusion, there is a significant potential of hortipastoral systems and proper management of soil organic matter to minimize adverse effects of climate, and improve productivity stability of intensive production systems. Single forage crops, either legume or grass, are more beneficial to onion yield than consortium of grass plus legumes.

RESUMEN.
El trabajo se desarrolló con el objetivo de identificar alternativas tecnológicas disponibles en el país en ganadería de cría y conocer más profundamente las causas de la existencia de una brecha entre la oferta tecnológica y su adopción. La zona de ejecución fue Sierras del Este (Uruguay), que comprende un área de aproximadamente 1.828.000 hectáreas, con predominancia de sistemas ganaderos de cría. Las principales actividades consistieron en consensuar, con un grupo calificado de técnicos vinculados a la cría vacuna, un listado de la oferta tecnológica disponible para esos sistemas, y caracterizarla en base a atributos; y definir a través de una encuesta y análisis de grupos foco las variables socio-económicas y actitudinales de los productores de la región y su relación con el comportamiento hacia lo tecnológico. Entre los resultados obtenidos están: 1) la oferta tecnológica disponible en el país para la cría vacuna, caracterizada y priorizada; 2) las causas que han limitado una mayor incorporación tecnológica en sistemas criadores; 3) una detallada caracterización de los productores de Sierras del Este y su predisposición hacia la adopción tecnológica (estrechamente relacionada a cinco variables: escala, disponibilidad de instalaciones, asistencia a reuniones técnicas, la percepción de que el negocio consiste en producir más y el tener asistencia técnica) y 4) la identificación de los principales canales y redes de información de estos productores. Estos estudios constituyen una base sólida para elaborar un plan de transferencia de tecnología basado en una comprensión afinada del proceso de toma de decisiones tecnológicas a nivel predial.

SUMMARY.
The work was developed with the aim of identifying alternative technologies available in the country in livestock breeding, and to deeply study the causes of the existence of a gap between technological offer and adoption. The Project was carried out in the Sierras del Este region (Uruguay), an area of approximately 1,828,000 hectares, where extensive livestock farming breeding systems are predominant. The main activities consisted on reaching an agreement on the technological offer available for those systems, and characterizing it, based on attributes, working with a qualified group of technicians on stock breeding; and defining -through a survey and analysis of focus groups- the socio-economic and attitudinal variables of the farmers in the region, and their relationship with their behaviour towards technological change. The results obtained were: 1) a systematization of the technological offer available in the country for livestock breeding systems, characterized and prioritized; 2) the causes that limited the technological adoption in those systems; 3) a detailed characterization of farmers located in Sierras del Este and their predisposition for technological adoption (closely related to five variables: scale, availability of facilities, attendance at technical meetings, the perception that business consists on producing more, and access to technical assistance) and 4) the identification of the main channels and information networks of these farmers. Those studies constitute a solid basis for developing a technology transfer plan based on a refined understanding of the technological decision-making process at the farm level. MenosRESUMEN.
