Organic Soils are categorized as ____________ and are additionally referred to as ____________ soils:
Show answer Hide answer
Answer: B. Histosols, peat & muck
Explanation
Soils dominated by organic matter rather than mineral particles have unique classifications. Soil taxonomy officially categorizes these organic soils under the order Histosols. Common field terms for these organic deposits include peat and muck soils. Histosols form in water-saturated environments where decomposing organic matter accumulates slowly. Peat consists of largely undecomposed plant remains with clearly visible structural fibers. Muck features highly decomposed organic material mixed with fine mineral sediment particles.
Drained organic soils support intensive vegetable production due to their high fertility. Wetland Histosols act as crucial global carbon sinks that regulate atmospheric gases. Agricultural management of peatlands requires careful water table control to prevent subsidence. Option A refers to Alfisols, which are mineral forest soils with subsurface clay accumulation. Option C designates Ultisols, which are strongly weathered acidic soils rich in iron oxides. Option D is incorrect because Histosols and peat and muck are the correct terms.
