Definition of podzol in English: podzol(also podsol) noun ˈpɒdzɒl Soil Science An infertile acidic soil characterized by a white or grey subsurface layer resembling ash, from which minerals have been leached into a lower dark-coloured stratum. It typically occurs under temperate coniferous woodland. 〔土壤学〕灰壤，灰化土 Example sentencesExamples - The soil is derived from podzols, with a sandy surface layer and clay at 1 m depth.
- In the study of radiata pine stands by Florence and Lamb, litter accumulation was greater on sandy podzols than on finer textured soils, despite similar rates of litter input.
- It contains soil types, such as podzols, chernozems, brown earths, chestnut soils, etc., familiar to many people.
- Although the information is based on a small set of plots in a localized area, the soil type and the soil texture at MSH have been found to be mainly ferro-humic podzol and sandy loam, respectively.
- Figure 5 clearly shows that in most cases rainforest stands on highly nutrient-depleted ferralsols, acrisols, and podzols of tropical lowlands attain diversity indices above 90% of the theoretical maximum.
Derivativesadjective Soil Science Both sites were previously dominated by Picea abies (L.) Karst. and were on acidic, sandy, podsolic soil with a raw humus horizon, with the mineral soil layers starting at approx. 20 cm depth. Example sentencesExamples - The results show that the podzolic soil zone in the Northeast is the most sensitive area to acid deposition, followed by latosol (found in wet subtropical and tropical forests), dark brown forest soil, and black soil zones.
noun ˌpɒdzəlʌɪˈzeɪʃ(ə)nˌpɑdzəˌlaɪˈzeɪʃən Soil Science It was traditionally an agricultural region, much of its territory covered in swamp and with poor soil undernourished from podzolisation, sustaining mainly meat and milk production. The soils are derived from schist and pegmatite, with some sites characterized by marked podzolization.
verb ˈpɒdzəlʌɪzˈpɑdzəˌlaɪz Soil Science Make or become podzolic. no object soil particle size analyses show that on some banks the soil has begun to podzolize Example sentencesExamples - Soils are podsolized, usually with a 3-10 cm layer of mor humus.
- The Black Sea coast has humus carbonate (differing in depth and humus content) and cinnamonic soils and the northern slopes of the main Caucasus spine have podzolized and pre-Caucasian chernozems (loamy loess).
