The ICEID or International Conference on Emerging Infectious Diseases is a conference for public health professionals on the subject of emerging infectious diseases. The International Conference on Emerging Infectious Diseases was first convened in 1998; ICEID 2006 marks its fifth occurrence.
Clay type, organic content, and soil structure also influence soil water retention. The maximum amount of water that a given soil can retain is called field capacity, whereas a soil so dry that plants cannot liberate the remaining moisture from the soil particles is said to be at wilting point.
Field capacity: the water content of a soil at the upper limit of the available soil water range. It is the amount of water remaining in a soil after the soil has been saturated and allowed to drain for approximately 24 hours. Permanent wilting point: the lower limit of the available soil water range. When plants have removed all of the available water from a given soil, they wilt and will not recover.
