• Hydroponics and Traditional Farming
• by admin

The population of the world is gradually rising and the natural resources are scarce and hence the need to use appropriate farming practices. Two main types of farming, hydroponics and traditional farming, are at the center of this discussion. Both the approaches are beneficial, but which one is more helpful for the future of agriculture? In this blog you will find information about the comparison between hydroponics and traditional farming in water usage, space utilization, yield, sustainability, and other factors to establish which system is more effective for modern agriculture.

How Does Hydroponics farming Work?

Hydroponics means the water is always in a closed circuit and the nutrients go straight to the root of the plant. Plants do not have to spend energy looking for nutrients in the soil which can be useful in the growth of more growth and higher yields. Example: Hydroponic vegetables are grown faster and also produce better yields than those grown in soil some of the vegetables that are grown through hydroponics include lettuce, spinach and kale.

What is Traditional Farming?

Open ground farming or soil farming is the most natural and oldest system of growing crops on the fields or in green houses by using soil. It has been done to support human beings for thousands of years. Farmers use rain, sunshine and soil fertility in the production of crops, but almost all of them now add chemical fertilizers and pesticides.

What is Involved in Traditional Farming?

Gardening is done on the ground; water and nutrients are taken up by the plants from the soil through the root. Agriculture is a repetitive activity that depends on climatic factors and other natural factors and thus vulnerable to the environmental changes. Example: Maize, barley and rice are crops that are usually produced on large scale farms using traditional farming techniques.

Main Differences Between Hydroponics farming and Traditional Agriculture

1. Water Usage

Hydroponics has a major advantage over traditional farming in that it is very efficient in its use of water. Current agricultural practices consume roughly 70% of the world’s freshwater and much of this water is not used efficiently or is allowed to run off, evaporate, or is used in inefficient irrigation systems.
Hydroponics: This is because hydroponic system may require only 10% of the water that is required in open field farming and this water is recycled. Plants use only the water that they require in the process, without wastage.
Traditional Farming: In conventional agriculture, a considerable amount of water is wasted either through evaporation or by runoff or by using methods like sprinkling or flood irrigation.

2. Space Efficiency

In traditional farming, crops need a large area to be planted, the availability of land is therefore a major constraint especially with the ever-increasing rate of urbanization.
Hydroponics: Hydroponic systems of crop growing are very efficient in terms of space utilization because the crops are grown vertically. Vertical farms let crops to be placed on top of one another, thus enabling greater food production in a given space, including in cities.
Traditional Farming: He said that traditional farming needs vast land for arable farming and urbanization is reducing the availability of the land at an alarming rate.
Example: Hydroponics in vertical structures has been made possible in urban areas such as New York city, where production of fresh produce in warehouse spaces cannot be made possible through traditional farming.

3. Crop Yield and Growth Speed

Hydroponics offers quick and higher yields because the plant environment is controlled and nutrients are readily available.
Hydroponics: Hydroponically grown plants are said to grow at a rate that is 30-50% higher than plants grown in soil. This is because they get steady, ideal nutrients and water, with no energy used in looking for these in the soil.
Traditional Farming: Yield increases in traditional farming are therefore pegged on the soil fertility, weather, and nutrient conditions. Yield may also be influenced by pest and diseases as well as unfavourable conditions such as drought.
Example: A hydroponic farm can harvest multiple crops of leafy greens, for example, within the same time it takes a conventional farm to harvest one crop; this means high productivity.

4. Environmental Concern and Sustainability

Both approaches affect the environment in a certain way, however hydroponics is much more beneficial when it comes to sustainability.
Hydroponics: Hydroponics also requires less water, less space and less use of pesticides and fertilizers. It also can be practiced indoors; thus it does not have such negative effects on the environment as agricultural runoff.
Traditional Farming: Conventional agriculture which involves the use of fertilizers and pesticides has negative impacts on the soil and water bodies and the environment in general. Also, soil erosion and deforestation in the cause of agriculture also cause climate change.
Example: In areas where soil has been eroded and made unfit for cultivation, hydroponics can be used as a better way of farming without affecting the environment.

5. Pest and Disease Control

Integrated pest and disease management is a major concern in traditional farming and results in the application of a lot of pesticides to the field, which are dangerous to the environment and human health.
Hydroponics: Hydroponic systems are closely controlled and therefore pests and diseases are kept to a minimum if they are present at all. This is due to the fact that the plants are grown indoors or in a closed environment and therefore have fewer incidences of pest attacks and therefore require less chemical control.
Traditional Farming: The traditional farms are most vulnerable to pest attacks and plant diseases, which can only be controlled by the use of chemicals. This not only affects the health of crops but also results to the presence of pesticide residues in foods and the environment.
Example: In large scale hydroponic farms, Integrated Pest Management strategies are applied, which reduces the cases of applying chemicals in controlling pest and at the same time protects the crops from pests and diseases.

Which of the Two Methods is Cheaper?

Despite the advantages of hydroponics, the costs of getting started are relatively higher than those of conventional farming.
Hydroponics: The installation of a hydroponic system – especially when it comes to an automated hydroponic system with the right kind of lighting and climate control – can be pricey. But these costs are usually recovered by the benefits of water, fertilizers, and land, as well as increased yields.
Traditional Farming: Conventional farming has relatively fewer capital requirements especially for small scale farmers. However, there are costs in the long run such as water, fertilizers, pesticides and the labour force which may be expensive. Also, traditional farming could be less remunerative than modern farming because the yields of traditional farming are low and the environmental conditions of farming are erratic.
Example: In the urban areas where land is a scarce resource and expensive, hydroponic systems may in fact be cheaper in the long run although the initial outlay is high.

These questions then arise; is hydroponics more sustainable?

Hydroponics is generally considered as a more efficient method of farming, especially concerning the issue of resource management.
Water Conservation: Hydroponics consumes much less water than conventional soil based farming.
Less Land Needed: Hydroponics systems especially the vertical farming use much less land than traditional farming.
Reduced Pesticide Use: That means the need to use chemical inputs is minimized due to the controlled environment of the greenhouses.
Climate Resilience: Hydroponics can produce crops all year round without being influenced by prevailing climate conditions.
Example: In places where water is scarce such as Israel hydroponics has become an important tool in the food production system as it uses very little water to produce food.

Challenges of Hydroponics

However, as much as hydroponics has numerous benefits, it has its drawbacks as well.

1. High Initial Investment

Establishing a hydroponic system may be expensive especially when moving to large scale production. This includes infrastructure costs, the costs of lighting, nutrients as well as the costs of technology.

2. Technical Expertise

Operating a hydroponic system needs some level of technicality in terms of nutrient rationing and the pH level. While automated, it still takes some time to get used to this change.

Conclusion

There are pros and cons of hydroponics and traditional farming so we have to weigh them. Hydroponics is suitable for cultures where both land and water are limited and can be used in practice of urban gardening and sustainable agriculture. Conventional farming, however, continues to be the most widely used approach to intensive crop cultivation in the rural areas of the country that has plenty of natural resources.

In the end, it is possible that the two systems will be used hand in hand, with hydroponics being used where it has an advantage over conventional farming, and the opposite.

In this regard, hydroponics becomes one of the most effective solutions for food security issues characteristic of the future with sustainability as the primary focus.
