The soil used in greenhouse farming known to be hard and saline, and be contaminated by chemicals as a result of excessive watering, fertilizing and harvesting. In addition the greenhouse soil contains harmful nematode and fungus, which are very difficult to get rid of once it contaminates the soil. For these reasons greenhouse soil is required to be either completely replaced or ventilated by hauling it outside every couple of years which has a high cost impacts to the farmers. In recent years, soilless farming became crucial because of these reasons. Several raw materials like perlite, stone clew, Coco peat etc. have been tried for soilless farming. These are few advantages of soil less farming over soil which are given below.
Enables farming where soil is not suitable: Since soil less farming eliminates the need for soil, farming can be done in fields where the soil is not suitable for plant growth.
Early delivery, efficiency and increased quality: Since soil less farming provides balanced Nourishment, plants develop early with increased quality.
Controlled plant nourishment: Soil less farming makes it possible to select the type and timening and adjust the quantity of the elements needed by the plants. This way controlled plant nourishment can be accomplished. By giving plants equal amount of fertilizers, it is possible to achieve equal crop growth and richness. It also makes it possible to avoid harmful effects of the elements (iron, zinc, copper, molybdenum etc.) in nutriments. Salt content and PH levels which has negative effects on plant growth can also be avoided. The nutrition intake of the plants is positively affected the temperature and oxygen level around the roots.
Water economy and control: Traditional farming requires extensive usage of water because of watering methods that have to use such as seepage, concealing in the soil or vaporizing. The operating costs are lowered since water used in soilless farming can be measured, it is not wasted and it is automated.
Reduction in energy consumption and labour requirement: Important savings can be achieved in energy consumption and labour force in soilless farming since it has technological and automated systems.
Disease and weed control: The liquid nutrition and growth environment can be sterilized. This way diseases caused by the roots can be avoided. Since the plants are grown in controlled environment (water and soil) there is no weed problem.
