  • Zinc Accumulation in Leafy Vegetable Irrigated with Secondary Treated Wastewater under Soil and Soilless Culture
    Applied Mechanics and Materials, 2014
    Co-Authors: Shahrul Azwan Shakrani, Mohd Fozi Ali
    Abstract:

    A field experiment was conducted to identify the risk associated with Zinc (Zn) accumulation in leafy vegetable irrigated with final (FSTW) and biological (BSTW) secondary treated wastewater under soil and Soilless Culture. For purposes of analysis, the Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) was used to determine the concentrations of Zn in wastewater, soil and plant samples followed by risk assessment. The results revealed that Zn concentrations of secondary treated wastewater were significantly higher in BSTW as compared to FSTW. Meanwhile, the Zn concentrations were found higher in plants grown under Soilless Culture as compared to soil Culture. Besides, the daily intake metals for Zn were found to be higher in Soilless Culture as compared to soil Culture. In addition, children were exposed to higher health risks than adults since the daily intake metals of Zn via consumption of plants was found to be significantly higher for children as compared to adults. However, the health risk index values were found to be less than 1. Thus, the risk associated with Zn contamination through consumption of plants irrigated with secondary treated wastewater by adults and children was no consequences and assumed to be safe in general. Yet, continuous monitoring is required in order to access possible detrimental effects to the human and environmental associated with secondary treated wastewater.

  • The effects of secondary treated wastewater irrigation on leafy vegetable growth under soil and Soilless Culture
    2013 IEEE Business Engineering and Industrial Applications Colloquium (BEIAC), 2013
    Co-Authors: Mohd Fozi Ali, Shahrul Azwan Shakrani
    Abstract:

    The population growth and rapid urbanization, as well as climate change and the indiscrimination use of freshwater has lead to the era of water resources dwindling and water scarcity problem worldwide. Therefore, most researchers have shown great interest in treatment, recycling and reuse of wastewater particularly in agricultural activities. In general, wastewater contains beneficial features such as nutrients that is required for plants growth and development. However, the application of wastewater in irrigation may result in the presence of harmful trace metals to the plants which contribute to the unfavourable effects to the people. This paper discusses the effects of secondary treated wastewater irrigation on Brassica Campestris Sp. Parachinensis vegetable growth with soil and Soilless Culture. The study involves the assessment of macronutrients and trace elements characteristics in wastewater, soil and plants. The results revealed the significant concentrations of macronutrients and trace elements in soil and plants irrigated with secondary treated wastewater. Besides, macronutrients and trace elements concentrations were found higher in plant growth under Soilless Culture as compared to soil Culture. However, most of parameters were found to meet the allowable limits regulated for health standard. Thus, secondary treated wastewater irrigation is applicable with proper monitoring and continuous assessments in order to prevent any long term risk associated to human and environmental.

  • Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems
    Agronomy, 2019
    Co-Authors: Nazim Gruda
    Abstract:

    Decreasing arable land, rising urbanization, water scarcity, and climate change exert pressure on agricultural producers. Moving from soil to Soilless Culture systems can improve water use efficiency, especially in closed-loop systems with a recirculating water/nutrient solution that recaptures the drain water for reuse. However, the question of alternative materials to peat and rockwool, as horticultural substrates, has become increasingly important, due to the despoiling of ecologically important peat bog areas and a pervasive waste problem. In this paper, we provide a comprehensive critical review of current developments in Soilless Culture, growing media, and future options of using different materials other than peat and rockwool. Apart from growing media properties and their performance from the point of view of plant production, economic and environmental factors are also important. Climate change, CO2 emissions, and other ecological issues will determine and drive the development of Soilless Culture systems and the choice of growing media in the near future. Bioresources, e.g., treated and untreated waste, as well as renewable raw materials, have great potential to be used as growing media constituents and stand-alone substrates. A waste management strategy aimed at reducing, reusing, and recycling should be further and stronger applied in Soilless Culture systems. We concluded that the growing media of the future must be available, affordable, and sustainable and meet both quality and environmental requirements from growers and society, respectively.

  • Do Soilless Culture systems have an influence on product quality of vegetables
    Journal of applied botany and food quality, 2009
    Co-Authors: Nazim Gruda
    Abstract:

    Summary In the hortiCulture industry, the focus has traditionally been on yield. However, consumers’ interest worldwide in the quality of horticultural products has increased in the recent past and will become the driving force in the future. Soilless Culture systems (SCSs), the most intensive production method in today’s hortiCulture industry, are based on environmentally friendly technology, which can result in higher yields, even in areas with adverse growing conditions. However, using SCSs does not automatically result in the production of high-quality vegetables. Numerous studies confirm that a SCS enables growers to produce vegetables without quality losses compared to soil cultivation. An adaptation of cultural management to the specific cultural system, as well as crop demand, can further result in the improvement of the quality of horticultural products.

    Co-Authors: Bu Chongxing, He Mei, Shi Lei, Zhang Yongping
    Abstract:

    The effects of two new Soilless Culture device on the tomato plantings was compared with the tubbish Ⅱ Soilless Culture device as control.The results showed that the tomato plants,which were cultivated in the new soilness cultivation device Ⅰ and Ⅱ,grew better and the friuts yields increased.When the plants was cultivated in the new device Ⅰ,the height,diameter,new weight,root activity,soluble sugar content in fruit,weight per fruit,single plant yield and so on were better than that in other devices,so the root growth and the fruit quality of the tomato could be improved in the new Soilless cultivation device Ⅰ.
