Hydroponics is the technique of growing plants in water based mineral solutions without the using soil. With the growing shortage of arable land around the world, hydroponics provide an innovative solution for sustainable agriculture in the future. The process involves the growth of small plants for fruits and vegetables by providing them artificial supports and dipping the roots in water based solutions. Nutrient content in these solutions is carefully maintained for the best yield.
Their adaptability to soil-free mediums and relatively better growth without the firm support of the ground has been pivotal in their compatibility with hydroponics. These plants have soft, sensitive roots and can be supplied with mineral-based solutions easily. Most of the nutrients the plant requires are available in water-soluble forms and thus tomatoes are a great pick among hydroponic plants.
Small shrubbery hosting raspberries can be cultivated using advanced hydroponic techniques. Concentrated water solution is modified to provide sufficient growth possibilities and nutrients like nitrogen and potassium. Day neutral raspberry plants are fast becoming a favorite with hydroponic gardeners and farmers. The luxury of growing berries on rooftop or balcony with just some water and chemicals has led many homeowners to try their hands at hydroponics.
Mint herb roots can easily absorb nutrition through the soft hairs. Being diminutive in size reduces the requirements for a firm base, but has no such affect on the need for nourishment for the mint plant.
Successes in small-scale hydroponic cultivation of rice has already been achieved, though only in ideal laboratory conditions. Implementing it on a large scale is still some time ahead in the future.
