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 permeability of soilâits capacity to transmit. water under pressureâmay be determined by indirect or direct. laboratory methods or by field methods. Most field methods are useful only below the water. table, but in this study a procedure for use above the water. table was investigated.
