Know what is hydroponics and how it has a beneficial impact on the environment plus other benefits and disadvantages.
Hydroponics is an innovative modern technique of growing plants directly in water without the use of soil. The plant is kept in still or flowing water in which the essential plant nutrients (fertilizer or chemicals) are mixed in required proportion.
However some medium is required to hold the plant in a steady position. Commonly used mediums are coco peat, pebbles, clay balls, rock wool, perlite, sponge, grow cubes etc.
Plants can be directly placed in water but this exposes the water to direct sunlight which may create problem of algae growth.
The foremost hydroponics benefits are that it does not require soil and hence can be practiced in any place and even a balcony or building terrace will do. It is clean and does not require handling of dirt causing materials.
Other benefits of hydroponics include absence of hard work of digging, weeding, timely daily watering etc. One can grow varieties of vegetable as well as flowering plants in a small place.
With a little bit of experience various types of fruiting vegetables and small plants producing fruits can also be grown.
The environmental benefits of hydroponics are varied and substantial. The fertilizers used are mixed in water and feed directly to the plants without dropping in the soil. Therefore there is no damage to soil. The seepage of fertilizers in the ground water is avoided.
In traditional as well as organic farming a lot of water is wasted. Hydroponics is even better than organic farming as it consumes 90% less water. This massive saving of water is one among the most outstanding environmental benefits of hydroponics.
In hydroponics pathogens like bacteria, fungus, etc. from soil do not come in contact with plants. This eliminates the use of harmful pesticides.
As hydroponic systems use vertical space plants can be grown in multiple layers. Hence output of produce can be 5 to 7 times more in the same area than traditional or organic soil farming.
It is possible to control individual plant nutrients to an accurate level. This helps in producing very healthy plants with optimum nutritious value.
Farm products like leafy vegetables and fruits grown hydroponically have a better market demand and sell for a higher price.
Hydroponic cultivation does not require any special type or size of place and hence can be adapted anywhere as per the availability.
The requirement of special systems makes the initial investment substantial compared to soil farming. Special instruments are also required to keep track of nutrient concentration, pH value and temperatures.
Systems have to be shielded from rain, snow and even too much sunlight. Readymade nutrient packs are fairly expensive and not readily available everywhere. A basic correct knowledge has to be acquired.
Continuous monitoring of the various parameters like PPM and pH has to be done every few days if not on a daily basis.
After knowing what is hydroponics and understanding all hydroponics benefits it a good idea to get hold of more information available on this site.
The environmental benefits of hydroponics far outweigh all other types of farming. The disadvantages of hydroponics are few and can be easily overcome.
