  • Hydroponic cultivation of lettuce (Lactuca sativa) using effluents from primary, secondary and tertiary + UV treatments

    ABSTRACTThe aim of this study was to evaluate the potential cultivation of lettuce (Lactuca sativa) with domestic wastewater effluents with different levels of treatment from a compact WWTP in Brazil. Vegetables were grown in five treatments: nutrient solution (control), secondary effluent diluted 50%, secondary effluent not diluted, tertiary effluent UV irradiated, and UASB effluent. ...

  • A probabilistic assessment of the contribution of wastewater-irrigated lettuce to Escherichia coli O157:H7 infection risk and disease burden in Kumasi, Ghana

    Wastewater use for vegetable production is widespread across the cities of many developing countries. Studies on the microbial health risks associated with the practice have largely depended on faecal indicator organisms with potential underestimation or overestimation of the microbial health risks and disease burdens. This study assessed the Escherichia coli O157:H7 infection risk and ...

  • A machine learning approach to crop localisation using spatial information

    This paper describes an approach to recognise and localise centres of mature lettuce heads in the field when the lettuce leaves obscure the distinctions between plants. This is of great value when using an automatic harvester in cluttered or closely planted vegetation. The aim of this work is to investigate and verify the potential use of spatial rather than visual clues for recognition and ...

  • Stud case study

    A major vegetable grower in Lantokia, Fiji, using soilless culture systems began to trial Amnite A-100. His crops consisted principally of lettuce, tomatoes, capsicums, cucumbers, zucchinis and melons. Before the trials they had been plagued with root diseases, mosaic virus and insect attack, control of which required constant use of pesticides and ultraviolet lighting. The first trials commenced ...

  • An assessment of the suitability of backyard produced compost as a potting soil

    Current scientific knowledge of compost is largely derived from research into commercially produced green compost. This has shown that such compost tends to have high pH, high conductivity, and potential for organic and/or mineral pollutants and therefore can be problematic for use in growing media at high inclusion rates. Little work has been undertaken at an amateur composting scale and it is ...

  • A co-beneficial system using aquatic plants: bioethanol production from free-floating aquatic plants used for water purification

    A co-beneficial system using constructed wetlands (CWs) planted with aquatic plants is proposed for bioethanol production and nutrient removal from wastewater. The potential for bioethanol production from aquatic plant biomass was experimentally evaluated. Water hyacinth and water lettuce were selected because of their high growth rates and easy harvestability attributable to their free-floating ...

  • Pesticides in the European Union

    There has been a sharply falling trend in the total volume of sales of agricultural pesticides in the EU between 1991 and 1995. But this was reversed in 1996. From 1991-1995, EU sales of pesticides, measured by weight of active ingredients (ai), fell by 13%. They then rose by 6% between 1995 and 1996 to stand at 299,826 tonnes ai. But this still put them nearly 8% below the 1991 figure. The use ...
