Hydroponics was introduced in the 17th century and involved growing plants without soil. It gained popularity in the early 20th century when researchers found it could successfully grow crops. In the 1930s, the term "hydroponics" was coined to describe growing plants in nutrient solutions. During World War II, hydroponics was used to grow food for troops stationed on islands. By the 1950s, commercial hydroponic farms existed worldwide. Hydroponic systems use liquid nutrient solutions and various media to support plant roots. They provide control over nutrients and environment but require more technical knowledge than soil-based gardening.

Hydroponics is a method of growing plants without soil by using mineral nutrient solutions in a water solvent. Some of the earliest examples of hydroponics date back thousands of years to structures like the Hanging Gardens of Babylon. Modern hydroponics was popularized in the early 1900s by William Gericke. Hydroponics offers several benefits over traditional soil-based agriculture including greater control over the growing environment, less water usage due to recycling, and the ability to precisely control nutrients. While hydroponics requires more precision, it is seen as a sustainable solution to issues with food and water supply.
The document provides an overview of hydroponics, including:
- Hydroponics is a technique for growing plants without soil by having roots absorb nutrients dissolved in water.
- It was popularized in the 1920s and was used by the US Army during WWII to grow fresh food for troops.
- There are several types of hydroponic systems that circulate nutrient solutions to plant roots, including wick, water culture, nutrient film technique, ebb and flow, and drip systems.
- Hydroponics has advantages like higher yields, healthier plants, and less water use than traditional agriculture but requires more initial investment and maintenance than soil-based gardening.
Green gardening involves cultivating plants in an environmentally friendly way to provide for community needs while improving the environment for future generations. It focuses on building good soil, minimizing pesticide and herbicide use, using organic fertilizers and amendments, appropriate watering, and selecting plants suited to the climate. Proper soil care, plant selection, and maintenance can help gardens thrive with fewer problems. Hawaii has unique climate zones and soils that require observation-based gardening suited to each area.
Urban farming techniques like hydroponics, aeroponics, aquaponics, roof gardening, and kitchen gardening allow for food to be grown in controlled environments within cities. Hydroponics grows plants without soil by using mineral nutrient solutions, while aeroponics uses no growing medium and sprays plant roots with nutrient mists. Aquaponics combines aquaculture and hydroponics by using fish waste as natural fertilizer for plants. Roof gardens and kitchen gardens make use of small urban spaces like rooftops and around homes to grow food. These controlled environment agriculture methods provide food and environmental benefits for urban areas.
Aquaponics is a sustainable farming method that combines raising fish and growing plants. Waste produced by fish provides nutrients for plants to grow soillessly, while plants purify the water for the fish. The presentation discusses the history of aquaponics and how the system works through the nitrogen cycle. It also outlines the advantages of aquaponics, components of the system, setup process, costs, maintenance required, and the future potential of aquaponics in areas like sustainable agriculture, urban farming, automation, and commercial applications.
entrepreneurship development in Horticulture with various Hydroponic SystemNikhil Ambish Mehta
Entrepreneurship development in Horticulture with various Hydroponic Systems was presented. Hydroponics is a method of growing plants using mineral nutrient solutions, in water, without soil. There are various hydroponic systems including passive capillary and active flood and drain systems. The nutrient film technique provides a constant film of nutrients to plant roots. Large scale hydroponic farming and vertical urban farming are growing to meet future food demands. Hydroponics has advantages like faster growth, fewer pests, and higher quality produce but also costs more initially and requires daily management.
Plant growth chambers are environmental test chambers designed to create optimal conditions for plant germination and growth by controlling temperature, humidity, and light. They are widely used in agriculture research on crop productivity, including plant breeding, nutrition, and photosynthesis. Various types of chambers exist such as reach-in and walk-in, and techniques like hydroponics, aeroponics, aquaponics, and vertical aquaponics allow for growing plants without soil. Aquaponics combines aquaculture and hydroponics in a symbiotic system where fish waste nutrients feed plants.
Aquaponic applications for the small farm are becoming all the rage, but how can it truly produce profitably? You need a complete system that supplies it's own feed that is mercury free, soy free, GMO free.

This document discusses different methods of farming without soil, including hydroponics, aeroponics, and aquaponics. Hydroponics grows plants using mineral nutrient solutions in water without soil. Aeroponics regularly sprays plant roots suspended in air with nutrient solutions. Aquaponics combines aquaculture and hydroponics by using fish waste as nutrients for plants which then filter the water for the fish. Vertical aquaponics stacks plants in towers to maximize space. Benefits include water conservation, pest resistance, and fast plant growth, but high startup costs and technical knowledge are required.
The document provides an overview of plant structures, functions, classifications, and life cycles. It discusses how plants are divided into underground roots and aerial shoots, and how different plant parts perform essential functions. Terrestrial plants are classified as bryophytes or tracheophytes, with tracheophytes having fully adapted to land through vascular systems. The life cycle involves alternating between haploid and diploid stages, and plants reproduce both sexually through fertilization and asexually via vegetative propagation.
Aquaponics is a farming method that integrates aquaculture and hydroponics, raising fish and plants together in a symbiotic system. The waste from the fish provides nutrients for the plants, which then purify the water for the fish. There are several types of aquaponics systems, but they all work on the same principles - fish waste is converted to plant nutrients by bacteria, and the plants remove these nutrients from the water which is then recirculated to the fish. Aquaponics has many advantages over traditional aquaculture and hydroponics as it utilizes the fish waste as fertilizer, produces high quality organic crops with minimal resources, and allows year-round production.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
ENVIRONMENT~ Renewable Energy Sources and their future prospects.tiwarimanvi3129
This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.
