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.
Soil and climatic factors that inï¬uence nutrient leaching In general, water transport below the rooting zone requires that the soilwater content exceeds field capacity and the water balance is positive,which means that water inputs with rainfall (and irrigation) exceedevapotranspiration.
