Hydroponics is a form of gardening and cultivation of plants that is especially popular for growing flavorful tomatoes. The various pollutants and microorganisms that plants are exposed to in soil often are not removed even after several years. This fact, along with others, has prompted researchers to search for ways to minimize the exposure of the plant to any medium that may carry factors that can add or contribute to human ill health. Hydroponics has been developed as a way in which plants do not use soil as a growing medium.
Soil Is Not Necessary
In hydroponic gardening, researchers have confirmed that soil fulfills the function of a reservoir where nutrients are stored for the plant’s consumption. The reservoir is simply where the plant’s food is stored. Therefore, this reservoir is not essential if the plant can get the nutrients in another manner. Hydroponics research has found that the nutrients in the soil dissolve when they come in contact with water, thus making it easier for the plants to absorb. Hydroponics has done away with the need for soil for some plants.
While most plants that are usually found in soil, terrestrial plants can actually survive even when they are soilless, as long as they have access to the right kinds of nutrients that are essential to their growth. Hydroponics may also provide a medium that may be more suitable for a healthy human life. These mediums are mineral wool, perlite and gravel. These are just there to provide the roots something to hold on to for stability.
The important factor in hydroponics is actually the mineral solution that provides the nutritional needs of the plant. Almost all plants can grow without soil as long as the nutrient based solution is present. The solution is actually formulated to meet the demands of a thriving and growing plant and given to the plant in doses. Not all plants can tolerate their roots being exposed to water all the time so some nutritional solutions.
Hydroponics has many advantages, such as cultivation in a clean environment without the fuss and mess of soil. Another advantage of hydroponics is the absence of many soil-borne diseases that target plants and produce damaged plants. Hydroponics also provides a solution in barren areas such as deserts and rocky areas for cultivating plants. Soil is not necessary to grow most plants including great tomatoes; therefore, greenhouses can be used for better crops that have nutrients directly provided to them without the using soil.
