Question

information about soilless agriculture

Answer 1

Soil less agriculture-
Hydroponics and aeroponics are both soil less agriculture techniques.
Hydroponics-
In hydroponics the plants are grown in water or in any inert growing medium that is void of any nutrients. All the required nutrients are provided via the nutrient solution used to water the plants.
Aeroponics-
Aeroponics is a technique or a subset of hydroponics that involves growing plants that have their roots suspended in a dark humid chamber which is periodically sprayed with nutrient rich mist. Aeroponics has many advantages over conventional methods of growing plants and also over hydroponics. The water consumption is 90 percent less and it allows for increased oxygen and nutrient intake since the mist particle size is very small.
Both the techniques are very useful in today's world where population is increasing rapidly and food security is really needed for all.

Answer 2

Soilless agriculture can be performed in controlled environments and virtually anywhere as it is not dependent on land space and fertility. It does not have the problems involved in traditional or industrial agriculture. That is why it is considered to be the way of future growing in so many parts of the world where there is little or no arable land.

Some benefits of soilless agriculture are :

In soilless agriculture the crops are grown indoors and are protected from the negative impacts of the elements.

The amount of water consumed can be monitored and used efficiently.

As the plants are grown indoors there is less risk of exposure to pests.

The crop is supposed to contain higher nutritional value in terms of vitamins and antioxidants.
