摘要: In soil physics the primary interest is in mixtures of a solid phase, liquid phase and gaseous phase. Each these phases itself mixture. The mixture numerous inorganic organic constituents, many which are positively or negatively charged. composition may more less deviate from that atmosphere above surface. aqueous dilute solution, balancing charges being strongly buffered by phases. For roots plants resilient provider nutrients receiver excrements. purposes it useful to regard root system as an additional solid- liquid-gas
