Hydroponics is a method of growing plants using nutrient solutions without the use of any soil. Researchers found that soil acts as a mineral nutrient but the soil is not essential to the growth.

Advantages:
Hydroponics, today, is an established branch of agronomical science. The progress is fast and the results obtained have proved it to be thoroughly practical and have definite advantages. The two main advantages of Hydroponics agriculture is because soilless cultivation are much higher crop yields. Secondly, Hydroponics can be carried out in places where ordinary farming or gardening is impossible. It is not only profitable undertaking but also proved great benefit to humanity. By the means of Hydroponics, all such places such as crowded city streets, without gardens in window-boxes or house tops and produce a supply of clean and health-giving crops.

Some other advantages include faster growth,consistent crops and the quality of it being excellent. There is also a reduction in area and weeds are non-existent. This method of agriculture uses automatic operations, which means there is less labour, less cost and no hard manual work. There is also, in addition no dirt, smells and also waterlogging never occurs. Waterlogging happens when air stops getting into the soil.

Higher yield:

Name of crop Hydroponic equivalent per acre Agriculture average per acre
Wheat 8,000 lb 5,600 lb
Oats 3,000 lb 1850 lb
Rice 12,000 lb 750-900 lb

Equipments used:
Modern farmers are concerned about the environments so they use a variety of tools that no only properly prepare a seedbed and carefully place the seed and fertilizers but also leave the soil surface covered with plant residue as possible for soil conservation. Some examples are: computer controlled applicators for pesticides, fertilizers, no-till or minimum-till planters. They are used to minimize usage and reduce the environmental impact.
