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.
The effective water capacity of a soil is the fraction of the void spaces available for water storage, measured in inches per inch. The minimum infiltration rate is the final rate that water passes through the soil profile during saturated conditions, measured in terms of inches per hour. The hydrologic soil properties are obtained by identifying the soil textures by a gradation test for each change in soil profile.
