There are several contaminants in the soil that do not go away for a very long time and pose a health risk to human beings. This has driven researchers to look for alternative ways to grow crops other than using the already polluted soil as a medium. Hydroponic Gardening is one such technique where plants do not make use of soil to grow and instead have alternative mediums while hydroponic nutrients are administered to them.
Research has shown that soil just acts as a storage medium for the plant’s nutrients. If the plant would get its nutrients and water from other sources other than soil, it would still survive. Since adding water in the soil dissolves the nutrients and make them easily absorbable by the plants, hydroponics seeks to do away with the need for soil in many plants while attempting to make them even better and more nutritious.
Plants found in the soil can actually live and thrive without soil for as long as they get the necessary hydroponic nutrients and water. Some of the most common alternatives for soil that hydroponics has proven effective include, but not limited to, mineral wool blocks, vermiculite and gravel among others. These mediums perform the same function as soil, that is, providing suspension for the roots of the plants to grow in and enhance their stability.
The hydroponic nutrient solutions that satisfy the plant’s nutritional requirement are the most important factors to consider. For as long as the correct hydroponic nutrients are supplied to them, many plants can grow without soil. The hydroponic nutrients are tailored to meet the requirements of a flourishing plant and administered in measured quantities. Since not all plants can hold water in their roots continuously, some hydroponic nutrient solutions are administered in doses.
Hydroponic gardening comes with an array of advantages, one of which includes cleaner farming. There are also reduced chances of soil borne diseases that mainly affect plants and destroy farm produce. Hydroponics makes it possible to grow crops in areas with unfavorable soil conditions like deserts and rocky areas. Greenhouses can also be introduced to produce better quality crops without using soil which is polluted.
