  • Survey Paper on Aeroponics
    International Journal of Innovations in Engineering and Technology (IJIET) http://dx.doi.org/10.21172/ijiet.134.06 Survey Paper on Aeroponics Ajay kumarD1, Namratha S.N2 1,2Assistant professor, Electronics and instrumentation, BMS college of Engineering, Bangalore, Karnataka, India Abstract- Almost all plants need soil for their growth. Nutrients present in soil help in the development of plants. Aeroponics is the method of growing plants in a medium without the use of soil. Here the plants are provided with a nutrient solution which circulates in the medium that holds the plant. The nutrient solution contains macronutrients and micronutrients which contribute to the healthy growth of plant. The Aeroponics is based on the opportunity of cultivating fruits & vegetables whose roots are not implanted in a bedrock (the case with hydroponics) or soil, but in ampules in which practices for spraying plant nutrition is delimited. In these containers, in our case pipe, roots can find the best ailment concerning oxygenation and moisture. These circumstances allow for healthier plant nutrition assimilation in a more balanced way, with consequential faster growth of the cultured plants. Keywords- Aeroponics, Hydroponics, Aquaponics, Aeroponics system, Aeroponics roots, Aeroponics growth. I. INTRODUCTION Aeroponics is the process of growing plants without using the substratum of soil. Aeroponics is a combination of two words „aero‟ and „ponic‟. „aero‟ meaning air and „ponic‟ meaning labour/growth. Therefore, aeroponics in whole suggests growing of plants in air. The plant is suspended in air using aeroponic system i.e. the roots are open and are in direct contact of air. Aeroponics culture varies from both the conformist hydroponics and aquaponics.

  • Aeroponics System of Cultivation in Horticultural Crops
    Vol.1 Issue-1, September,2020 Aeroponics System of Cultivation in Horticultural Crops Deeptimayee Sahoo Ph.D Research Scholar Dept. of Vegetable Sciences, Orissa University of Agriculture and Technology, BBSR, Odisha-751003 Mail- [email protected] ARTICLE ID: 007 Population of earth is expected to rise by 3 billion people. It is estimated that approximately 109 hectares of additional traditional land will be needed to feed them. Only 80% of the Earth’s arable land is suitable for farming now. A greater quantity of hectares with optimum inputs is needed every day to feed the rising population. This chain of high priority problems requires an improvement in the management of the use of resources so that human consumption has the priority in its use. To solve the problems mentioned, new farming methods have been searched, one of them being aeroponics. With this technique, the plants are held by certain structures that are maintained in a way that the roots are sustained up in the air. Aeroponic literally means “growing in air.” An aeroponic system is medium-less in that the roots of the plant are free hanging inside an open root-zone atmosphere. Aeroponics structure supplies optimum levels of water, nutrients and air to the growing chamber. Aeroponics is the process of growing plants in an air or mist environment without use of soil or an aggregate media. The word aeroponic is derived from the Latin word ‘aero’ (air) and ‘ponic’ means labour (work). This is an alternative method of soil-less culture in growth-controlled environments. The aeroponic culture technique is an optional device of soil-less culture in growth-controlled environments such as greenhouses.

  • A SWOT ANALYSIS of the VERTICAL FARM 2018, June 1
    BSC Thesis Name: Sanne van Asselt Registration number: 941120020100 Supervisor: J. H. Trienekens Chair group: Management Studies (MST) A SWOT ANALYSIS OF THE VERTICAL FARM 2018, June 1 Abstract The vertical farm is in its early state, leaving many questions unanswered and many open gaps in our current level of knowledge. There is at the moment not known what the opportunities and threats of a vertical farm are. To create more knowledge on vertical farms we conducted a SWOT analysis to answer the question: what are the most promising opportunities and most dangerous threats for the vertical farm? For the strengths we sought to find subjects that created a competitive advantage for the vertical farm by having a resource that greenhouse and conventional farm do not possess or any activity the vertical farm does better. For the weaknesses we looked for resources a vertical farm does not possess and activities a vertical farm is not doing well. Lastly the PESTLE analysis was used to find the opportunities and threats for the vertical farm. The high efficiency, the high quality, the innovative technology and the high costs are the most recurrent themes in the strengths, weaknesses, opportunities and threats of the vertical farm. The results of the SWOT analysis show that there are two most promising opportunities and three most dangerous threats. The first most promising opportunity is the environmental opportunity. A vertical farm can become a circular economy and also energy efficient by further enhancing their innovative technology. The second opportunity is the economic opportunity, which is the niche market and selling opportunities (both) based on the high quality and high level of food safety of the crops grown in a vertical farm.

  • Dry-Fog Aeroponics Affects the Root Growth of Leaf Lettuce (Lactuca Sativa L
    Original Paper Environ. Control Biol., 53 (4), 181187, 2015 DOI: 10.2525/ecb.53.181 Dry-fog Aeroponics Affects the Root Growth of Leaf Lettuce (Lactuca sativa L. cv. Greenspan) by Changing the Flow Rate of Spray Fertigation Yosuke HIKOSAKA, Michio KANECHI, Mizuki SATO and Yuichi UNO Bioresource Science, Graduate School of Agricultural Science, Kobe University, Kobe , Hyogo 6578501, Japan (Received April 16, 2015; Accepted July 28, 2015) The growth characteristics and physiological activities of leaves and roots of lettuce cultivated in dry-fog aeroponics with different flow rates of nutrient dry-fog (FL, 1.0 m s1; NF, 0.1 m s1) were investigated under a controlled environment for two weeks and compared to lettuce cultivated using deep-flow technique (DFT). The growth of leaves of FL and DFT was not different and was significantly higher than that of NF. The amount of dry-fog particles adhering to the objects was higher in FL than in NF, so that the root growth in NF was significantly higher than that of FL. The respiration rate of roots was significantly higher in dry-fog aeroponics, but the dehydrogenase activity in the roots was significantly higher in DFT. There were no differences in the contents of chlorophyll and total soluble protein in the leaves or the specific leaf area. Photosynthetic rate and stomatal conductance were higher in dry-fog aeroponics. The contents of nitrate nitrogen, phosphate and potassium ions in the leaves were significantly higher in DFT, but the content of calcium ions was significantly higher in FL. Thus, changing the flow rate of the dry-fog in the rhizosphere can affect the growth and physiological activities of leaves and roots.

Gibson 2,* 1 Cellular and Molecular Biology Program, Department of Food Science, University of Arkansas, Fayetteville, AR 72701, USA; [email protected] 2 Department of Food Science, University of Arkansas, Fayetteville, AR 72704, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-479-575-6844 Received: 13 February 2019; Accepted: 7 March 2019; Published: 15 March 2019 Abstract: Controlled environment agriculture (CEA) is a growing industry for the production of leafy vegetables and fresh produce in general. Moreover, CEA is a potentially desirable alternative production system, as well as a risk management solution for the food safety challenges within the fresh produce industry. Here, we will focus on hydroponic leafy vegetable production (including lettuce, spinach, microgreens, and herbs), which can be categorized into six types: (1) nutrient film technique (NFT), (2) deep water raft culture (DWC), (3) flood and drain, (4) continuous drip systems, (5) the wick method, and (6) aeroponics. The first five are the most commonly used in the production of leafy vegetables. Each of these systems may confer different risks and advantages in the production of leafy vegetables. This review aims to (i) address the differences in current hydroponic system designs with respect to human pathogen internalization risk, and (ii) identify the preventive control points for reducing risks related to pathogen contamination in leafy greens and related fresh produce products. Keywords: hydroponic; leafy greens; internalization; pathogens; norovirus; Escherichia coli; Salmonella; Listeria spp.; preventive controls 1.
