Literally, "Hydroponics" means "Water Work. No organic matter is present so nourishment Nutrient is not available to the plants in the same was as it is in a soil garden. Instead, nutrients are added to the water. So, as plants are watered, they are also fed.
Economics[ edit ] Opponents question the potential profitability of vertical farming. The analysis concluded that "food miles are, at best, a marketing fad. Similarly, if power needs are met by fossil fuels, the environmental effect may be a net loss;  even building low-carbon capacity to power the farms may not make as much sense as simply leaving traditional farms in place, while burning less coal.
Therefore, supplemental light would be required. Bruce Bugbee claimed that the power demands of vertical farming would be uncompetitive with traditional farms using only natural light.
Plumbing and elevator systems are necessary to distribute nutrients and water. Vertical farms require much greater energy per kilogram versus regular greenhouses, mainly through increased lighting. The amount of pollution produced is dependent on how the energy is generated.
Greenhouses commonly supplement CO2 levels to 3—4 times the atmospheric rate. Also, necessary ventilation may allow CO2 to leak into the atmosphere.
Greenhouse growers commonly exploit photoperiodism in plants to control whether the plants are in a vegetative or reproductive stage.
As part of this control, the lights stay on past sunset and before sunrise or periodically throughout the night. Single story greenhouses have attracted criticism over light pollution. The most common method of spreading the effluent over neighbouring farmland or wetlands would be more difficult for an urban vertical farm.
The study's quantitative framework projected annual food production of — million tonnes, energy savings ranging from 14 to 15 billion kilowatt hours, nitrogen sequestration betweenandtonnes and stormwater runoff reductions between 45 and 57 billion cubic meters annually.
All-season farming multiplies the productivity of the farmed surface by a factor of 4 to 6 depending on the crop. With crops such as strawberries, the factor may be as high as Changes in rain patterns and temperature could diminish India's agricultural output by 30 percent by the end of the century.
Conservation[ edit ] Up to 20 units of outdoor farmland per unit of VF could return to its natural state,   due to VR's increased productivity. Vertical farming would thus reduce the amount of farmland, thus saving many natural resources.
Producing food indoors reduces or eliminates conventional plowing, planting, and harvesting by farm machinery, protecting soil and reducing emissions.
Resource scarcity[ edit ] The scarcity of fertilizer components like phosphorus  poses a threat to industrial agriculture. The closed-cycle design of vertical farm systems minimizes the loss of nutrients, while traditional field agriculture loses nutrients to runoff and leeching.
Traditional agriculture disrupts wild populations and may be unethical given a viable alternative. One study showed that wood mouse populations dropped from 25 per hectare to 5 per hectare after harvest, estimating 10 animals killed per hectare each year with conventional farming.
VF reduces some of these risks. These habits lead to health problems such as obesityheart disease and diabetes. Poverty and culture[ edit ] Food security is one of the primary factors leading to absolute poverty.
Constructing farms will allow continued growth of culturally significant food items without sacrificing sustainability or basic needs, which can be significant to the recovery of a society from poverty. This would allow large urban centers to grow without food constraints.

This biogas could then be burned to generate electricity for the greenhouse. Combining these technologies and devices in an integrated whole is necessary to make Vertical Farming a reality.
Various methods are proposed and under research.
The most common technologies suggested are:Skimping on lawn care and mowing closely give weeds the opportunity to move in, and as most of us know, getting rid of weeds is a lot harder than preventing them in the first place, because weeds tend to be hardy souls with huge root systems.
Chop yard and garden waste into smaller pieces (a lawn mower works great!) to speed the decomposition process. Finished compost can be used to build soil anytime of year without fear of burning plants or polluting water.
Agricultural technology - Factors in cropping: The kind and sequence of crops grown over a period of time on a given area of soil can be described as the cropping system.
It may be a pattern of regular rotation of different crops or one of growing only one crop year after year on the same area.
Early agricultural experiments showed the value of crop rotations that included a legume sod crop in. By Geoff Wilson.
