웹2024년 9월 14일 · ACRISOLS (AC) The Reference Soil Group of the Acrisols holds soils that are characterized by accumulation of low ac-tivity clays in an argic subsurface horizon and by a low base saturation level. Acrisols correlate with ‘Red-Yellow Podzolic soils’ (e.g. Indonesia), ‘Podzolicos vermelho-amarello distroficos a argila de 웹13. Soil Colloids. Colloids consist of clay minerals and organic matter, and play critical roles in soil chemical, physical, and biological properties. Colloids are very small in size. The majority of charges in soil comes from colloids, making them important for cation exchange capacity, buffering capacity, and retention of nutrients like Ca 2 ...
