New advances in horticulture have led to all sorts of changes in how farmers and gardeners grow crops. These advances not only benefit the farmers using these techniques, but also benefit the environment. They combine advances in technology with the world’s understanding of how plants grow in order to create revolutionary plant-growing techniques.
Hydroponic gardening uses less water than traditional soil-based gardening by continually recycling the water in the hydroponic garden. With soil gardening, a lot of the water ends up seeping into places where the water is not used by plants. Plants have to be watered more often than usual to ensure they're properly hydrated. Much less water is wasted with hydroponics gardening because the water is sent directly to the roots. Much of the water ends up being recycled.
Pesticide and Fertilizer Reduction
The amount of nutrients and chemicals needed to grow a plant are reduced with hydroponic gardening, as these nutrients don't seep into the soil where they are consumed by bacteria. Pesticides and fertilizer also don’t run off into and possibly contaminate water supplies. Pesticides are needed less, as some of the worst pests are found in soil. Herbicides are not needed at all. Pesticides are also reduced through integrated pest management. Integrated pest management involves using predator bugs, pest-resistant plants, traps, barriers and controlled amounts of pesticide in order to reduce the amount of pesticides needed.
Plant vitamins and micronutrients are added to soil or to hydroponics gardening systems. These nutrients not only make the plants healthier, causing them to grow better, but also increase the amount of nutrients available to the humans who consume these plants. Biostimulants are available that increase the number of hairs on plants, which increase the number of nutrients that can be taken up by these plants.
Plants that are cloned tend to grow faster and healthier than the original plant that was cloned. Cloning plants is becoming cheaper and easier through the development of cloning products. Plants cuttings root faster with the use of plant-rooting hormones.
Bottom heat mats are available to speed up seed germination. New growing mediums like long fiber sphagnum moss, horticultural perlite, horticultural vermiculite and peat-based potting mix replace traditional soils and create environments that promote quicker growth for plants.
