A Guide To General Hydroponics
The general hydroponics technique dates back to several hundred years. So, it is not a new technique. The example of general hydroponics includes hanging garden of Babylon, floating gardens of China and Aztecs and Egyptian hieroglyphic record. Several impressive progresses have been made in the general hydroponics technique.
Everyday several experiments have been going on to improvise general hydroponics using varied technique. Scientists and horticulturists have achieved great success in improving and updating general hydroponics. In today’s world this technique is in demand and constantly on the rise. In the period of the Second World War hydroponics was used in the pacific on non arable islands to grow fresh crops for the troops based there.
Its Success Commercially
General Hydroponics has become increasingly popular with commercial growers and they are extensively using it to make fresh produce. Traditional farmers are also attracted to the benefits of using this method.
Due to climatic conditions Israel has been using this method and has also improved a lot in hydroponics technology. Nicaragua has used this technology to produce pepper to export it to different countries as well as US. Arizona is another country where you can find the largest hydroponics. In 2005 this country could produce tomatoes to the tune of 125 million pounds.
General Hydroponics Advantages
The main advantage of general hydroponics is that it gives high yield when compared to traditional soil based agriculture system. It is very useful in parts of the earth where crops cannot be grown in soil. It eliminates the need of insecticides and pesticides for the crops. Thus it makes the water, air, soil and food healthier and cleaner.
Nutrition requirement
As far as nutrients are concerned, it depends on the plants that are being cultivated and differ considerably. Each plant has its own need during their growing period. Each stage has different nutritional needs which may need various mixtures of products.
General hydroponics needs nutrients that get dissolved in the water and are in the form of organic and ionic substance. Macronutrients that are commonly used are potassium phosphate, magnesium sulfate, potassium nitrate and calcium nitrate.
Advancement in Technology
Benefits can be observed through various ways. In terms of productivity, general hydroponics gives more yields because of negligible use of pesticides and insecticides. Plants are constantly provided with nutrients to get more yields. The growth is less due to low level of carbon dioxide. Artificial lighting can also be done to increase the yield.
