Last week focused on bulk density as a property of soil, and how lower values were associated with good soil structure and high organic matter content, while higher values were associated with soil compaction. We ended with the note that soils compact… more »
Last week covered pore space, or the holes in soil. This week we look at the opposite of holes — the solids in soil. Pore space is expressed as a percentage of soil volume, while solids are expressed as a mass per volume. This measurement is referred to… more »
We’ve spent quite a few weeks examining soil structure, from soil horizons right down to the level of cations and anions and the role they play. Having zoomed in closer and closer each week on smaller and smaller components, this week we’ll… more »
So far we’ve gone over cations,and exchangeable cations and where there are cations (the positively-charged ions) there will be anions, the negatively-charged ions, because ions come in pairs. Some anions are also soil nutrients — and essential… more »
