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 Soil Water Characteristics Program estimates soil water tension, conductivity and water holding capability based on the soil physical properties of texture, organic matter, gravel, salinity, and compaction.he Soil Water Characteristics Program estimates soil water tension, conductivity and water holding capability based on the soil physical properties of texture, organic matter, gravel, salinity, and compaction.
