Hydroponics as a division of hydroculture entails growing plants in the absence of soil. Only water and nutrient solutions are used. Sometimes water is not used, but nutrients solutions alone in which terrestrial plants are immersed. Water is supplied to such plants. Water and nutrient delivery can be achieved through various methods including directly hanging root systems inside nutrient solutions, placing root systems containers with substrates, and misting the roots.
Substrates replace soils in cases where plants are suspended in the substrates. Various kinds of substrates exist today. Major ones include sawdust, perlite, pebbles, wood chips, rockwool, and sand. Substrates are made with great ability to allow gaseous exchange and prevent water loss. Root systems grow deep into the substrates to offer support. Many people in the world are engaged in this form of agriculture because it presents several benefits. Today one can spot a hydroponics store anywhere.
This technology has a long history. Earliest publication on the technology was done in 1627 by Francis Bacon. The publication was printed after the death of Bacon and since then research in that direction increased. Several publications were done since 1699. The technology was modified severally as research continued to perfect it.
Today, only two major kinds of hydroponics exist, that is, solution culture and medium culture. Solution cultures do not involve use of any solid medium. Nutrient solutions are the only ones used. On the contrary, solid mediums are used in medium cultures to provide support to root systems.
Solution cultures can be placed into three subcategories. Static solution cultures, aeroponics, and continuous-flow solution cultures are the three kinds of solution cultures. The mediums used in medium cultures determine the name of the culture. That is why there are cultures like gravel and sand cultures. Another criterion that is used to classify hydroponics is mode of irrigation. Here are two main categories, that is, sub-irrigation and top irrigation.
Hydroponic reservoirs used today are usually made from plastic material although wood, metal, vegetable solids, concrete, and glass have been used in the past. In fact, some reservoirs are still made from such materials. To avoid growth of algae, the reservoirs or containers must be placed in places where there is not light totally.
Nutrients are dissolved before being supplied to plants. Nutrients are usually in form of ions and inorganic form. The number of recipes used to make hydroponic solutions is huge. The desired composition is attained by mixing numerous chemicals together. Potassium phosphate, potassium nitrate, magnesium sulfate, and calcium nitrate are among chemicals used to provide macronutrients. As plants continue to absorb water and nutrients from soils, salt concentration increases to harmful levels. Close monitoring is required to avoid that.
The technology is being exercised on large scale in several countries. The constant supply of nutrients to plants coupled with lack of pests leads to high yields. However, plant growth is limited by lower levels of Carbon dioxide and restricted sunlight exposure.
