How Hydroponics Can Impact Agriculture

Rachel Smith, Applied Technology Review | Tuesday, June 29, 2021

A hydroponic farm's fundamental concept is that water is used in place of soil.

FREMONT, CA: A hydroponic vegetable garden offers many advantages. They can help solve problems without excessive space or water use, produce high-nutrient vegetables, and produce vegetables faster than traditional growing methods. It seems pretty inevitable that this farming method will become a primary source of fruits and vegetables in the future.

Some of the advantages are as follows.

Space Maximisation

Hydroponics requires less space than soil-grown plants. Depending on the system, when combining hydroponics with vertical farming techniques, they can use up to 99% less land than typical farming techniques. The smaller footprint of hydroponic plants does not spread to search for nutrients and moisture. Instead, water and nutrients are delivered directly, intermittently, or constantly, depending on the hydroponic technique. Each plant's root system takes up far less space to grow more plants in a smaller space. When adding to vertical stacking methods, it's easy to see how much smaller area is needed to make a hydroponic garden than a traditional one.

Enables micro-climate

Hydroponic gardens can be easily stored within a greenhouse or other structure. This means they can have their micro-climates isolated from many difficulties traditional farmers have to deal with. They are not left to pest mercy and need not be treated with a variety of insecticides. In temperature-controlled facilities, plants can be grown year-round regardless of outside climate or weather. And with artificial growing lights, the amount of sun available is no problem.

Makes higher yields

Creating ideal conditions ensures that plants receive the perfect amount of nutrients in direct contact with roots. Additionally, microclimates enable year-round growth and faster crop cycles. All this adds up to yields far higher than traditional farming methods. Indeed, we found our hydroponic greenhouses can produce about 240 times the yield of other farming practices.

Require less work

Without tilling, weeding, herbicide and insecticide application, and other labour-intensive farm jobs, hydroponics offers a lighter worker load and can be easily managed with far fewer person-hours. This both reduces crop costs and frees up time for other pursuits. Indeed, one single part-time worker can fully manage a small hydroponic greenhouse.

Minimises Supply Chain

With hydroponics, heavy energy use can be cut. Hydroponic greenhouses can be built in neighbourhoods where traditional farms cannot thrive. This means they can meet their local communities' needs without wasteful transportation and questionable preservation processes. Simplifying the food chain means that high-quality products can be grown locally, even in urban areas, and then distributed to the community with less waste and more remarkable freshness.
