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 volumetric soil moisture content at the wilting point will have dropped to around 5 to 10% for sandy soils, 10 to 15% in loam soils, and 15 to 20% in clay soils. The total available water (holding) capacity is the portion of water that can be absorbed by plant roots.
