Does gun control make society safer? Gun control issues In this article we shall be taking a look at the major advantages and disadvantages of gun control.
Print This Article Image source: By completely eliminating soil as a growing medium for plants, and by avoiding wastage of water into the ground, these intensive methods make localized food production sustainable and profitable, in spite of scarcity of water and fertile land.
Hydroponics Hydroponics is a time-tested method widely used for growing tomatoes and lettuce in greenhouses. The plants are grown directly in a water-based solution containing all the essential nutrients required by them. Inert media like pebbles or clay pellets are sometimes used for supporting the plants.
The absence of soil completely eliminates disease-causing soil organisms and weeds.
Consequently, labor, as well as the use of use of herbicides, is greatly reduced. The controlled environment protects the crop from most of the air-borne pests. Occasional infestations and fungal infections can be tackled effectively by targeted use of pesticides and fungicides. Hydroponics typically uses only 20 percent of the water required for traditional cultivation.
Periodical replacement of the nutrients-depleted water is the main recurring cost.
Electrical conductivity of the solution is monitored daily to maintain optimum nutrient levels. The solution has to be changed when chemical imbalance is detected. Energy requirements include the aeration and pumping of the solution every 4 to 6 hours.
Hydroponic culture can be done indoors under artificial lighting, but, while it makes year-round production of food possible, it pushes up the energy bill. Aquaponics Aquaponics is a complex cultural method that evolved as an effective solution for the recycling of the waste generated in aquaculture.
Based on the wetland ecosystem in which plants and animals support each other, the nitrogenous waste produced in the aquaculture of fish, prawns or clams is used as fertilizer for plants grown hydroponically. Aquaponics enlists the help of nitrogen-fixing bacteria and worms to breakdown the fish waste into nitrates and nitrites that can be absorbed by the plants.
The resulting clean water is then recirculated into the aquaculture tank. The main input in an aquaponic system is fish food besides the power for the running of the electric pumps that recirculate the water round the clock. Since the water loss, mainly from transpiration by plants and evaporation into the atmosphere, is minimal, replenishment is needed very rarely.
This reduces the water requirement of aquaponics to about 2 percent of that of traditional cultivation. Aquaponics Even though both the methods qualify as high-yielding systems that maximize space utilization and considerably reduce the dependency on water, each system has certain advantages and disadvantages: Power is required to run the aerators and pumps that keep both the hydroponic and aquaponic systems running.
Daily power expenditure is higher in aquaponics with its frequent water circulation. However, it is easily offset by the higher returns from both the fish and the plant crops.
Periodic replacement of the hydroponic solution results in large amounts of waste water. Disposal of this fertilizer-rich water into natural water bodies is an environmental risk. It can promote algal growth and be a threat to aquatic ecosystems. In aquaponics, solid waste generated by the fish in excess of what gets broken down by the worms and bacteria is the only waste.
Since it is organic in nature, it can be disposed of into the common drain or used for composting. Monoculture and the risk of diseases. In hydroponics, the liquid medium for each crop is specifically formulated to meet its specific nutritional requirements; hence, monoculture is preferred for the maximum utilization of the fertilizer input.
Disease risk, especially from fungal infections, is higher in hydroponics; and an outbreak can spoil the entire batch. Hence, special measures are taken to protect the crops from contamination.
Fish waste being a general organic fertilizer, a variety of plants can be grown together in aquaponics. In a well-established system, the different components such as fish, worms, plants and various bacteria form a natural ecosystem that resists diseases.
Necessity of solid growing media Solid media can be completely eliminated in hydroponics; its only function is providing an anchor for the plants. When pebbles or clay balls are used, 6-inch deep beds are the norm. Aquaponics also does away with soil, but other coarse media like clay pellets or rock pieces are used to provide a home for the beneficial bacteria similar to the ones that exist in the soil.While many people have decidedly formed opinions on gun control, the debate is complicated and has strong supporters on both sides.
