Hydroponics: A Review Soil-less Culture

Abstract

Agriculture has always has been a practice done in open or soil based field. But with increasing
population, decrease in per capital land availability, this practice is facing challenges more than before. With ever
growing urbanization and industrialization, as well as increasing sea level and iceberg melting, available land is
decreasing at much more rapid rate. Along with this use of chemical fertilizers, poor water management, rid lands,
decrease in water table, polluted water bodies and many more such activities it is creating problems which we have
never faced before. With such developments, it will be hard and impossible for us to feed entire population in future
with present agricultural practices. Even more problems arise, when plants get infected by various diseases due to
climate changes, pests, and chemicals in soil.
Under such undesirable conditions, possible solution for this unseen problem is Hydroponic culture or also known as
soil less farming. The whole system involves using of water and soluble minerals mixture to grow plants, in our case
agricultural products. It is possible to improve space as well as available resources to perform Hydroponic farming at
the same time with promising results all over the world.
This paper describes design and development of system using raspberry Pi for image processing to recognize plant
diseases and a soil less farming process to increase the productivity of farms.
