  1. Web app for real-time monitoring of the performance of constructed wetlands treating horticultural leachates

    Cáceres, Rafaela; Pol, Enric; Narváez, Lola; Puerta, Anna; Marfà, Oriol
    Leachates produced in intensive horticulture must be collected, reused and eventually treated in order to prevent environmental pollution of water bodies. Constructed wetlands (CW) try to emulate natural wetlands, where pollutants such as nitrates are removed through the denitrification process. CW are a simple and sustainable technique with a low energy demand that are being used to purify different effluents. No information is currently available on tools used to monitor the performance of such systems in terms of nutrient removal efficiency. Nor is information available on the use of Information and Communication Technologies (ICT) tools to share news on this...

  2. Produtividade de alho vernalizado em função de fontes e doses de fósforo

    Macêdo, Fábio Silva; Sedoguchi, Ériko Tadashi; Souza, Rovilson José de; Carvalho, Janice Guedes
    The objective of this research was to verify the influence of sources and doses of phosphorus in the productivity of vernalized garlic in soil with low phosphorus content. The experiment was carried out in field conditions in the Horticulture Sector at the Universidade Federal de Lavras. Three sources (simple superphosphate, with 18% of P2O5; triple superphosphate, with 41% of P2O5 and magnesium term phosphate, with 17% of P2O5), three doses (200, 400 e 600kg ha-1 de P2O5), and one additional treatment, that didn't receive manuring with phosphorus were tested. The application of 200kg ha-1 of P2O5, using triple superphosphate provides...

    Castillo Girón, Víctor Manuel
    El autor intenta introducir a una discusión sobre las externalidades de las actividades productivas de las llamadas agroempresa, resaltando los aspectos que han cobrado mayor relevancia. Se trata de un esfuerzo que pretende sintetizar todo un trabajo que tiene como referente la aplicación de una encuesta aplicada a los actores económicos durante el periodo de julio de 1998 a junio de 2000.

  7. Key Gaps for Enabling Plant Growth in Future Missions

    Motil, Brian; Hanford, Anthony; Barta, Dan; Massa, Gioia; Anderson, Molly; Quincy, Charlie; Romeyn, Matthew; Wheeler, Ray; Fritsche, Ralph
    Growing plants to provide food or psychological benefits to crewmembers is a common vision for the future of human spaceflight, often represented in media and in serious concept studies. The complexity of controlled environment agriculture, and plant growth in microgravity have and continue to be the subject of dedicated scientific research. However, actually implementing these systems in a way that will be cost effective, efficient, and sustainable for future space missions is a complex, multi-disciplinary problem. Key questions exist in many areas: human medical research in nutrition and psychology, horticulture, plant physiology and microbiology, multi-phase microgravity fluid physics, hardware design...

  8. Rose and Pear Breeding in Nineteenth-Century France: the Practice and Science of Diversity

    Pavie, Cristiana; Philips, Denise; Kingsland, Sharon

    Horticultural plant breeding underwent significant development in France in the
    nineteenth century. A wide community of breeders, naturalists, botanists and
    scholars was interested in plant breeding; some cared primarily about finding the
    most effective ways to get new varieties, while others wanted to understand this
    new diversity. They faced a number of practical and theoretical problems con-
    cerned with the causes of variation, the genealogy of variation, and the nature of
    hybrids. This chapter focuses on two of the most widely bred woody plants in
    France, roses and pear-trees, in order to highlight the particularities of these per-
    ennial plants,...

  10. Cultivares injertados de pimiento morrón con uso eficiente de nitrógeno para mejorar la producción

    García Bañuelos, Mónica Liliana; Sánchez Chávez, Esteban; Antero Gardea Béjar, Alfonso; Parra, Juan Manuel; Muñoz Marquez, Ezequiel; García Carrillo, Mario
    Los invernaderos de hortalizas injertadas requieren de tecnología, lo que puede traer múltiples beneficios a la horticultura mexicana. Además del uso de cubiertas fotoselectivos, injertar plantas deben tenerse en cuenta debe rendimientos de pimiento son incrementados. En este trabajo se evaluó el desempeño de nitrógeno (N) por el uso eficiente ‘Fascinato’ (F) y cultivares injertados en rizomas ‘Terrano’ (T) y ‘Jannette’ (J). Dicha evaluación se logró mediante el análisis de variables fisiológicas y bioquímicas involucradas en el metabolismo de N entre las plantas injertadas y no injertadas. Los resultados señalan que las plantas injertadas a cabo de manera más eficiente...

  12. Desarrollo de materiales superabsorbentes biodegradables procesados a partir de subproductos agroindustriales

    López, M.L.; Romero, A.; de la Fuente, J.; Ruiz, M.; Bengoechea, C.; Guerrero, A.; Aguilar, J.M.; Cordobés Carmona, Felipe
    There is an increasing need to shift towards the development of sustainable and environmentally friendly materials in the world market nowadays. Superabsorbents polymers (SAP) are a good example of this new type of materials, being based on renewable natural components with a lower cost. Notwithstanding, the production and commercialization of biocompatible and biodegradable SAP are still very limited, which makes the need of research on this field pretty clear. This work pretends to cover that need establishing as its main objective the development of new materials that display a great water absorption capacity (absorbents and superabsorbents). These materials will be produced...
