Basic Properties of Soilless Substrates for Urban and Peri -Urban Agriculture (UPA) Food Production

Soilless agriculture is steadily becoming a subject discussed broadly in industrial and scientific communities. In this point is more important to know about a growing medium. Growing substrates is a substance through which plant roots grow and extract water and nutrients. Selecting a good growing medium is fundamental to good soilless agriculture. This study focused on the physical, chemical and hydrological characteristics of coco pith, perlite,
vermiculite, vermin compost, sand, rice husk, paddy straw, sawdust and Rockwool. However, no one growing medium works best in all situations because the media's physical, chemical and hydrological properties are not constant, but rather ca n be affected by the grower. This article mainly, to understanding the dynamic nature of soilless substrates. The results showed that the physical, chemical and hydrological characteristics of the soilless media.
