Soil Humus Questions. Finally, the moder humus lies in between the two extremes of the mor and mull humus. Mor on the other hand is a coherent upper soil layer, rich in humus and thoroughly interwoven by dark fungal hyphae - a condition which, as Müller pointed out, is outside the sphere of agricultural practice. %PDF-1.3 %���� According to this study two humus form orders, Mulls and Moders, and six groups were identified. It contains more mineral matter, is darker in color than peat, and is characterized by the presence of a thick humus (H)* layer. mor- is found i harsh climatic conditiob abd abundance of recalcitrant organic matter typical of unproductive.

Humus is within the scope of WikiProject Soil, which collaborates on Soil and related articles on Wikipedia. Table 1 represents some characteristics of the humus types and the stands. Humus is the most complex organic molecule found in soil, and as a result it is the most stable organic molecule. Nevertheless there are differences in parameters used for description and classification of humus forms as well as in scaling these parameters. * Footnote: L, F, H are organic horizons with differing degrees of decomposition. Humus forms are most broadly divided into three orders: mor, moder, and mull. Mor means few species are present.

Factors influencing humus forms and forest litter properties in the mid-mountains under temperate climate of southwestern Poland Author: Labaz, Beata, Galka, Bernard, Bogacz, Adam, Waroszewski, Jaroslaw, Kabala, Cezary Source: Geoderma 2014 v.230-231 pp. It is characterized by the presence of a thick litter (L)* layer with thin or no fermentation (F)* and humus (H) * layers. minérale: mull = terreau forestier, mor = humus des forêts rési-neuses et de bruyères. No pretense is made that this key covers all humus types. Differences in soil characteristics and animal communities between the two phases of the forest cycle corresponded to those generally observed between mull and moder, except for collembola which are generally more abundant in the thick organic layers of moder soils. The oxidation/reduction potential was determined on a considerable number of samples belonging to the three broad groups of forest humus: (1) earth mull, (2) duff mull, and (3) mor. 8. Mull is a type of humus which occurs in soils under cultivation. Peat humus is the dead, highly decomposed organic material that accumulates in the lower levels of peat bogs. For both Histo and Epihisto Semiterrestrial humus forms, the 5 basic forms (Mor, Moder, Amphi, Mull, Anmoor) are equilibrium points in a continuum running from least biologically active and badly aerated (Mor) to more active and better aerated (either Mull or Anmoor) humus forms according to the water regime (fluctuating or stable, respectively). Forest Humus - Coggle Diagram: Forest Humus (Mull Humus Form, Moder Humus Form, Mor Humus Form, Humus Qualities) It is black in colour and generally contains the majority of members of Ericaceae and mosses. 0 ^ � � � � � � � � � � � Humus Types Three humus types, mor, moder, and mull form in upland forests under aerobic conditions. xref 158 19 0000000016 00000 n The humus form is a mull, with a well‐developed hemorganic A horizon.

The NMR spectra of correspondingly sized soil fractions were similar for both soils. The hypothesis that roots enhance soil-N turnover in humified soil organic matter (SOM) (mull) but not in lignified SOM (mor) was tested in a study involving the growth of eight species of tree seedlings on the two contrasting humus forms. 0000030415 00000 n 0000001351 00000 n F (fermentation): some of the original structures are difficult to recognize. and may reduce a mull with granular structure to firm mull, or may mix the H-layer of a mor with mineral soil creating a mull-like condition.

(2) Mull humus: It is porous. This type of humus is characterized by neutral pH, C/N ratio nearing to 10 and ability to creation stable mineral-organic complexes. Decomposition is accomplished by bacteria and invertebrates. The humus form is a mull, with a well-developed hemorganic A horizon. The polyphenols of fresh green and dried leaves, litter, and superficial humus from mull and mor sites were examined by paper chromatography and paper electrophoresis. It is generally used by florists. I like myth debunking as much as I like gardening. HMFA revealed the importance of depth to explain this contrast among humus forms, using humus layers as diagnostic tools in both inert and living components. The concept of mull, moder, mor is applicable for forest covers. Humusica 2, article 18: Techno humus systems and global change – Greenhouse effect, soil and agriculture : In: Applied Soil Ecology, Elsevier, 2018, 122 (Part 2), pp.254-270. Decomposition is accomplished primarily by fungi. R � � . After Müller, and … 0000000758 00000 n Twenty different humus samples belonging to the 4 main groups: earth mull, duff mull, true mor, and infiltrated mor, were subjected to the following determinations: pH, sp. 0000005147 00000 n Moder is sometimes known as insect mull because its distinguishing characteristic is the presence of many arthropod fecal pellets. 163 0 obj << /Linearized 1 /L 874892 /H [ 1103 248 ] /O 161 /E 35451 /N 27 /T 871613 >> endobj Hemic peat A moderately decomposed class of peat characterized by 1/3 to 2/3 recognizable plant fibers (compare to sapric and fibric peat). Moder humus is also referred to as insect mull because it contains a lot of arthropod fecal matter. Mor humus is characteristic of the Fire-Dependent forest/Woodland System. A mull-humus formation is characteristic of hardwood forests, deciduous forests, or grasslands in warm, humid climates. 162 0 obj The essential difference between a Moder and a Mor organic deposit is that the Mor … There are three basic types of upland humus forms: Mull Moder Mor; In situations which favour deciduous forests the "MULL" or "MODER" will be favoured however where coniferous forests dominate it is more common to see a combination of either the "MOR" or the "MODER" form of humus accumulate. The role of polyphenols in the stabilization of protein in superficial humus and the relationship of this role to mull and mor formation is discussed. The turnover rate for humus ranges from 2 to 5% per year, depending on climatic conditions (Wagner and Wolf, 1998).This can be compared with the degradation of lignin shown in Figure 16.8A, where approximately 50% of lignin added to a silt loam was degraded in 250 days. The porous, crumbly humus rapidly decomposes and becomes well mixed into the mineral soil, so that distinct layers are not apparent. k�. Moder forms … We have studied a poplar plantation downwind of an active zinc smelter. 0000001103 00000 n Soil nutrient ions can attach to the humus and afford plants those nutrients but humus … The mineralization of A statistically significant pH difference was recorded between mull humus and the remaining humus types. The passage from mor to mull along the transect was abrupt, mor turning to mull at 250 m from the smelter, though there was a progressive decrease in heavy metal deposition. Moder is sometimes known as insect mull because its distinguishing characteristic is the presence of many arthropod fecal pellets. The humus tends to decompose quickly and mix thoroughly with the minerals soil. Differences in humus type have been regarded as indicative of changes in site productivity, and of the two main humus types which are now recognized, mulls are generally considered to be more fertile than mors. HMFA also showed contrast between … The NMR spectra of correspondingly sized soil fractions were similar for both soils. The results suggest that there are marked differences between the oxidation/reduction potential of freshly collected samples of mull and mor humus types.
