What is the type of soil that contains a mixture of sand silt clay and humus?
As Loam soil has almost equal proportions of sand, silt & clay the bacterial activity is very high. Hence bacterial activity is highly predominant in loam soil. So humus content may be high in loamy soil than clay which has high organic content but poor aeration due to which bacterial activity is low.
What make up loam?
Loam contains a mixture of sand, silt, clay and humus in relatively even concentrations (about 40-40-20% concentration respectively).
Does bedrock turn into humus?
No. Humus is organic matter, and formed over the years as living organisms (mostly plants) die and decompose in the soil. It is about 58% carbon, by weight. Bedrock can decompose, too, but it never becomes humus. Depending on the type of bedrock, it breaks down into sand, silt, gravel and clay minerals. Limestone bedrock may dissolve.
What are the meanings of 'loam' and 'humus'?
Loam is a general term applied to soil that has relatively equal parts of sand, clay and silt. You might even see terms such as sandy loam or clay loam, indicating it has a little more of that component. Humus refers to organic material from animals and plants such as peat, manure and compost. Humus breaks down readily in the soil, releasing its nutrients. Soils with lots of humus are called rich soils… soils with very little humus are called lean.
