Aeroponic Based Controlled Environment Based Farming Systemiosrjce
Controlled Environment Farming is one of the emerging technologies in the farming and agriculture
industries nowadays. Aeroponics is an optimized process developed for growing crops and plants in an air
medium without the use of soil or an aggregate medium by spraying the plant’s roots with an atomized or
sprayed, nutrient-rich water solution. Various automated farming system has been developed using sensor
networks and control systems to improve agricultural produc-tivity. Traditional farming techniques are complex
and strictly influenced by soil conditions, climate, weather, crop types, and so on. Authors have proposed a
system in which an environment monitoring, quality evaluation and crop growth, data recording, and online
data submitting and multiplatform compatibility were integrated. The control system based on agricultural
information measured by field monitoring sensors is a proved effective method to improve quality of
agricultural product in a greenhouse.
In this study, we proposed an intelligent control system for an aeroponics-based greenhouse, which
consists of data collec-tion/monitoring system, control system, centralized sever, and multiplatform web-based
controlling/monitoring application for agricultural facilities. The prototype system for establishing a low-cost
aeroponics-based greenhouse control system can be designed based on an open-source development board
called Raspberry Pi. The system can be used both locally and over the Internet, which has a large set of
controlling and monitoring function for the greenhouse. The system is proposed to achieve maximum
optimization, control, quality, automation, etc. in an aeroponics-based greenhouse.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
