Linkages between aggregate formation, porosity and soil chemical properties

Popis výsledku v původním jazyce

Linkages between soil structure and physical?chemical soil properties are still poorly understood due to the wide size-range at which aggregation occurs and the variety of aggregation factors involved. To improve understanding of these processes, we collected data on aggregate fractions, soil porosity, texture and chemical soil properties of 127 soil samples from three European Critical Zone Observatories. First, we assessed mechanistic linkages between porosity and aggregates. There was no correlationbetween the fractions of dry-sieved aggregates (; 1 mm, DSA) and water-stable aggregates (; 0.25 ?m, WSA). Soil microporosity and micro + mesoporosity increased with increasing abundance of aggregates, though this correlation was only significant for theWSA fraction. The fraction of DSA did not affect the overall porosity of the soil, but affected the ratio between micro- and mesopores (?30 kPa/?0.25 kPa), suggesting that micropores are dominantly located within DSA whereas mesopores ar
