Development of Sustainable Hydroponics Technique for Urban Agrobusiness

Abstract

In this work develop a system that uses a combination of advancements in fuel cell technology, solar power, and hydroponics. The developed system effectively distributed in the agricultural sector, resulting in a drastic increase in urban farming and the enhancement of traditional rural farming methodologies. Hydroponic farming is a technique by which the crops are grown without soil, it benefits the environmental by eliminating erosion and water consumption by the crops, it also reduces the labor-intensive work involved in traditional framing technique. The introduction of automation in this hydroponic system and improve the monitoring of the consistency of the yield. The implementation of fuel cell technology and solar panels aids in reducing the carbon footprint of the system. As good as it sounds in efficiency and protecting the environment, it is challenging to get the right and ambient conditions for the plants to grow. Water and nutrients must be provided in a required ratio while being constantly monitored with the help of an array of sensors calibrated and coded with Raspberry Pi. The automated system helps us to maintain optimal conditions for plant growth. The primary power supply is provided by a fuel cell or even magnesium salt water fuel cell. which uses an anion exchange membrane to generate electricity to power the automation equipment for the hydroponics system. The function of solar cell is used to facilitate the fuel cell to generate hydrogen which then circulated to the fuel cell. This potentially replaces the need for setting up of massive external power source for electrolysis.

Study of Natural Regeneration of Sogdian Ash (Fraxinus Sogdiana Bunge) and Silvicultural Measures to Promote it in the Sharyn River Floodplain of Almaty Region

“…As for the Almaty region, it covers all natural zones of the country, from sandy flat deserts to high mountain peaks and permafrost. There are specially formed and preserved relict trees among the varied landscapes 17) . There are species of trees that grew naturally in this area before the Ice Age, and have survived ever since, and one can only imagine them.…”

Toward Sustainability: An Overview of the Use of Green Hydrogen in the Agriculture and Livestock Sector

“…Experimental applications of hydrogen from renewable energy sources in agriculture have been conducted in three areas: off-road agricultural vehicles [ 59 ], greenhouses [ 60 , 61 ], and hydroponics [ 62 , 63 ]. For instance, in a vineyard in northeastern Spain, Carroquino and co-authors (2019) installed a renewable energy system.…”

“…The hydrogen was generated by water electrolysis fed by the solar panel during daylight, then stored for use by the fuel cell in the absence of sunlight. The residual heat was used to heat the plants [ 63 ].…”

Application of Controlled Release Fertilizer (CRF) in Supporting the Growth and Productivity of SS Sakato Shallot

“…Sulphur (S) plays a significant role in the nutrition of onion plants for flavor and taste development 18) . Some trace element are also used in helping the shallot to attain its optimum productivity since the plant needs selected nutrients to grow, other than water dan sunlight 19) . CRF is also coated by using humic acid to improve the characteristic and properties of the fertilizer.…”
