About new methods in agriculture,
Today, let’s talk about new methods and technology in agriculture. Which will very beneficial in the future in the agriculture sector. We are going to talk about 5 new methods in agriculture.
We will talk about,
- Tissue culture
Hydroponic is the predominant system of growing that used in vertical farming. This method is a soil-less type of farming because it needs no soil for the plant to grow. the knowledge of soil-less farming called hydroponics.
In this method, plants get nutrients from water instead of soil because the elements are already dissolved in water.
That solution is frequently observed and monitored to ensure that there is the maintenance of the correct chemical composition in the nutrient.
Plants grow through a process called photosynthesis, in which they use sunlight and a chemical inside their leaves called chlorophyll to convert carbon dioxide (a gas in the air) and water into glucose (a type of sugar) and oxygen. Write that out chemically and you get this equation:
6CO2 + 6H2O → C6H12O6 + 6O2
There’s no mention of “soil” anywhere in there—and that’s all the proof you need that plants can grow without it.
What they do need is water and nutrients, both easily obtained from the soil.
But if they can get these things somewhere else—say, by standing with their roots in a nutrient-rich solution—they can do without soil altogether. That’s the basic principle behind hydroponics.
In theory, the word “hydroponics” means growing plants in water (from two Greek words meaning “water” and “toil”), but because you can grow plants without actually standing them in water, most people define the word to mean growing plants without using soil.
How does hydroponics work?
Artwork: In the nutrient-film technique, nutrient constantly drips past the roots of the plants, which grow out from an inclined tray.
The nutrient is pumped back up to the tray and a second pump adds oxygen through an air stone (a piece of porous rock that lets air bubble through it—just like in a fish tank).
There are various different ways of growing things hydroponically. In one popular method, you stand your plants in a plastic trough and let a nutrient solution trickle past their roots (with the help of gravity and a pump).
That’s called the nutrient-film technique: the nutrient is like a kind of liquid conveyor belt—it’s constantly sliding past the roots delivering to them the goodness they need.
Alternatively, you can grow plants with their roots supported by a nutrient-enriched medium such as Rockwool, sand, or vermiculite, which acts as a sterile substitute for soil.
Another method is called aeroponics and it’s typified by a popular product called the AeroGarden (see box below).
Although the name suggests you’re growing plants in the air, the roots are actually suspended inside a container full of extremely humid air.
Effectively, the roots grow in a nutrient-rich aerosol a bit like a cloud packed full of minerals.
In theory, you can grow any plant hydroponically but—as is always the case with gardening—some things inevitably do better than others.
Fruit crops such as tomatoes and strawberries, and lettuces and herbs, are among plants that do particularly well.
Benefits of Hydroponic farming
- By providing constantly available nutrient, This plant grows very fast than it would in the soil
- By using this method we can reduce the use of water and we can save water
- Less use of herbicides and pesticides so also its environment friendly
- By using this method vertically, so you do not need much land for farming

2. Aeroponics: Growing plants with no soil and very little water
This method of aeroponic is made by the national aeronautical and space administration. This method was invented by NASA to grow plants in space in the 1990s
The word “Aeroponic” is from the Greek meaning of Aer and ponos. Aeroponics means growing plants with no soil and very little water.
In this method no need for any medium to grow the plants. it is considered a type of hydroponics since water is used in Aeroponics to transmit nutrients.
Aeroponic systems nourish plants with nothing more than nutrient-laden mist.
The concept builds off that of hydroponic systems, in which the roots are held in a soilless growing medium, such as coco coir, over which nutrient-laden water is periodically pumped.
Aeroponics simply dispenses with the growing medium, leaving the roots to dangle in the air, where they are periodically puffed by specially-designed misting devices.
In aeroponics systems, seeds are “planted” in pieces of foam stuffed into tiny pots, which are exposed to light on one end and nutrient mist on the other.
The foam also holds the stem and root mass in place as the plants grow.
What Can You Grow with Aeroponics?
Anything, in theory. In practice, aeroponics systems are primarily used for the same applications as hydroponics systems, including leafy greens, culinary herbs, marijuana, strawberries, tomatoes, and cucumbers. One exception is root crops, which are impractical in a hydroponic system, but well-suited to aeroponics, as the roots have plenty of room to grow and are easily accessible for harvesting.
Benefits of Aeroponic farming
- Less cost than other methods
- Comfortable for working with plants and easy to maintain
- When one plant does become affected then we can remove that plant without disrupting other plants

3. Aquaponics: Plants and fish farming together
This method is like hydroponics but in some way, it’s better than hydroponics because it contains plant and fish farming together.
In this method, Fish grow in indoor ponds with plants are planted, Plants get rich nutrients from the waste of fish.
This waste of fish acts as a rich source of food for plants.
An Aquaponic method depends on different live components to work effectively. The main live components are plants, Fish, Bacteria.
What Can You Grow with aquaponics?
The fish and plants that you select for your aquaponic system should have similar needs as far as temperature and pH.
As a general rule, warm, freshwater fish and leafy crops, such as lettuce, greens, and herbs will do the best.
Most commercial growers raise leafy crops, but you can grow all kinds of plants in aquaponics.
At our demonstration facility at Nelson and Pade, Inc.®, we have raised lettuce, swiss chard, kale, collards, herbs, peppers, tomatoes, cucumbers, beets, radishes, carrots, green onions, leeks, beans, peas, kohlrabi, cabbage, broccoli, cauliflower, sunflowers, edible flowers, and aloe.
We even have tropical fruit trees in our aquaponic systems! Yes, we grow bananas, limes, oranges, lemons, and pomegranates year-round in aquaponics!
Benefits of Aquaponic farming
- Plants get nutrients from fish waste
- Efficient and suitable productivity
- Fish are free from expansion hormones and antibiotics
- Allows continuous making of food
- It produces both protein and vegetable crop
- Liberation from soil-borne diseases
4. Monoculture: Multiple crops planted in a specific area
The monoculture farming method is the method of planting one crop within a specific area.
Most of the commercial farms in the UNITED STATE are now using this method for better output.
Many indoor farms growing medicinal herbs and plants by using this method.
Monoculture is the method of producing a single crop, single plant or livestock variety, species, or Breed in a field or farming system at a time. When one crop is grown alone in a single field, it’s called a monoculture farm.
This method makes it easier to cultivate, sow seed, control weeds, and harvest. So we can get better quality and quantity of output.
Benefits of monoculture farming
- Less plant opposition for nutrients, space, and solar radiation
- Control of undesirable organisms
- High quality and quantity of output so higher profit
- Reduce the cost of other machinery operation
5. Tissue culture: The growth of cells from tissue from the multicellular organism in vitro
Tissue culture is the multiplication of tissues separate from the organisms. This is naturally facilitated via the use of the liquid, semi-solid, or solid growth medium, such as agar.
Tissue culture normally refers to the culture of animal cells, with the more specific term plant tissue culture being used for plants.
The tissue culture is used for ornamental plants like orchids, dahlia, carnation, etc. This method is also known as micropropagation because a small amount of tissue is used.
benefits of tissue culture
- New plants formed by this method are disease-free
- Very small space is needed for this method
- This method is very useful to create new varieties in the small time period
- This method is not affected by weather or season
