Float system is a less-intensive and low-cost technology that enables efficient control
of the nutrition of the growing plants. The findings of experiments carried out under float system
in various crops with or without organic fertilization need to be reviewed. The importance of float
system for growing plants without inorganic fertilization and chemical pesticide use needs also
to be pointed out. Float system can enhance root development of growing plants and control the
height of produced transplants. This can result in increased yields and improved transplant
quality, not only in tobacco transplant production systems but also in the case of vegetable crops
such as tomato or lettuce. In the case of crops like tobacco and for the success of float system
alkalinity and oxygen content of the water in the nutrient solution and selection of the growing
media are crucial. Regarding vegetable crops, the combination of float system and organic
fertilization can enhance root development in tomato as compared to the combination and lettuce
resulting in high-quality products. Several aromatic and medicinal plants, including basil and
spearmint, provide high yields and good product quality in floating systems especially along with
organic fertilization. Conclusively, float system is a major method for producing high quality
products or transplants. Further investigation is needed regarding the combined effects of organic
fertilization and float system on more crops and under different climatic conditions
