Expression of andic properties in soils from Galicia (NW Spain) under forest and agricultural use
Abstract
The organic matter (OM) of soils with andic properties has long been considered highly stable because of the presence of Al-humus complexes and sorption of organic ligands onto amorphous compounds. In this study, we characterized soils under different land use regimes located within an amphibolitic massif close to Santiago de Compostela (Spain), where soils with andic properties are present. Slash and burn agriculture was a common practice in the area until the second half of the 20th century. Thereafter, modern agriculture was progressively introduced into the area (AGR soils), and the rest of the land was either reforested or abandoned (FOR soils). We found that the mean organic C content of AGR soils (48.7 g kg - 1 ) was ∼ 50% that of FOR soils (94.2 g kg - 1 ). Mean soil pH was significantly greater (P < 0.05) in the AGR than in the FOR soils (4.95 compared with 4.63), which is attributed to liming and Ca-phosphate fertilization of the former. Mean concentrations of the Al forms studied (extractable with CuCl 2 , sodium pyrophosphate, ammonium oxalate, or NaOH) were significantly smaller (P<0.01) in AGR (1.4, 4.9. 9.3, 11.0 g kg - 1 , respectively) than in FOR soils (3.9, 10.2, 16.5, 17.9 g kg - 1 , respectively). The results show the vulnerability of the OM and Al-humus complexes in these soils to modern agricultural practices, which has led to the attenuation - and in some cases even the disappearance - of andic soil properties in a relatively short time (< 30 years) following changes in land use/management. We propose the inclusion of the formative element 'andic' in the criteria for the definition of Umbrisol subunits; this would avoid the abrupt discontinuity observed in the current World Reference Base classification.

Publisher Summary This chapter outlines the present knowledge of the nature, properties, and genesis of clay minerals in soils derived from volcanic materials. It discusses the significance of volcano-derived ejecta as a parent material, the major clay mineral constituents, weathering of volcanic materials, and clay mineral formation and transformation. A distinctive feature of soils derived from volcanic materials is the occurrence of a unique clay-size mineral assemblage dominated by noncrysta...

Current soil-forming processes were studied in a nonallophanic Andosol from the Vosges mountains (north-eastern France). For this purpose, we conducted comparative studies on the organo-metallic fraction dynamics of selected profiles of an Andosol and other typical soils from this region, Cambisol and Podzol. These soils are derived from old volcanic rocks under mesic soil temperature and udic soil moisture regimes. The Andosol profile displayed the characteristics of nonallophanic Andosols: lar...

Abstract The clay mineralogy and chemistry were determined for five pedons derived from tephra and volcaniclastic materials in northern California. These soils are believed to have formed under vegetation and climatic conditions similar to those at present; coniferous vegetation and a xeric soil moisture regime with approximately 1000 mm of annual precipitation. The five pedons showed a surface enrichment of organic carbon (3.6–6.7%), an acidic to neutral pH (5.3–6.9), and a generally low base s...

This study was undertaken to elucidate the interaction mechanism between NOM (natural organic matter) and iron oxide surfaces and to develop a predictive model for NOM adsorption and desorption. Results indicated that ligand exchange between carboxyl/hydroxyl functional groups of NOM and iron oxide surfaces was the dominant interaction mechanism, especially under acidic or slightly acidic pH conditions. This conclusion was supported by the measurements of heat of adsorption (microcalorimetry), F...

Abstract The clay minerals in a series of soils from rhyolitic ash having the same stratigraphy but different leaching environments were estimated quantitatively by oxalate dissolution, infrared spectroscopy, differential thermal analysis, electron microscopy and X-ray diffraction. Three soils were studied in detail. These were the Kereone soil (mean annual rainfall 1200 mm), the Ohaupo soil (1400 mm) and the Mairoa soil (2600 mm). The Kereone soil contained halloysite as the predominant clay mi...

SUMMARY Organic matter-sesquioxide complexes in podzol B horizons are precipitated at specific carbon/sesquioxide ratios. Field data indicate that only part of the potential acidity is neutralized and that the maximum C/R2O2 ratio (minimum metal content) at which organic complexes will precipitate depends on pH of the soil and consequently on parent material and profile development. Although C/R2O3 ratios may be used regionally to predict the transition from soluble to precipitated complexes, su...

SUMMARY A set of well-drained soils in Galicia, formed from gabbros, amphibolites and schists, with udic moisture and mesic temperature regimes, are studied. All but one of the surface horizons show an‘exchange complex dominated by amorphous material’(ECDAM); consequently, most soils are classified as Andosols (FAO) or as different subgroups of Dystrandepts (Soil Taxonomy). The soils on gabbros and amphibolites frequently have‘andic properties’so, following the ICOMAND proposals, five of the 12 ...

The usefulness of various techniques for characterizing poorly- ordered inorganic gel systems in clays is considered. Many established instrumental techniques are unsuitable, but thermal methods, chemical dissolution techniques, and specific surface reactions are more appropriate. The reaction of fluoride with clays is used as an example of the latter and methods for detection and monitoring of the fluoride uptake are described. Its value is demonstrated for studying gel materials in soils and r...

Summary Sorption on the mineral matrix is an important process restricting the movement of dissolved organic matter (DOM) in soils. In this study, we aimed to identify the chemical structures responsible for the retention of DOM by sorption experiments with total DOM and acidic humic substances (AHS), containing humic and fulvic acids, on soil samples and minerals (goethite, ferrihydrite, and amorphous Al(OH)3). The AHS remaining in solution after sorption were studied by 13C nuclear magnetic re...

Summary Potassium pyrophosphate (0.1m) removes very little Fe from crystalline Fe oxides at pH 10, but peptizes finely divided hydrous amorphous oxides and organic matter in soils. Fe and C contents of extracts from each horizon of twenty-six British soil profiles show distinctive patterns, independent of the residual dithionite-soluble Fe. Thus extracts of humus Fe podzols have maximum Fe and C in the B horizon, peaty gley podzol has maximum Fe in the B horizon but maximum C in the surface. The...

Andosols often accumulate soil organic matter (SOM) in large amounts. To investigate the factors controlling the stability and lability of organic carbon (OC) in humus horizons of Andosols, we selected 19 A horizon samples (surface and subsurface horizons) from the Field Station of Tohoku University including areas where benchmark soil profiles of non-allophanic Andosols are distributed. We determined the soil properties possibly controlling the OC accumulation, such as pH(H2O), 1 M KCl-extracta...

Abstract Andosols (or Andisols) possess several distinctive properties that are rarely found in other groups of soils. These properties are largely due to the dominance of short-range-ordered minerals (allophane, imogolite and ferrihydrite) and/or metal–humus complexes (Al/Fe–humus complexes) in their colloidal fraction. While several papers have extensively reviewed the nature and properties of short-range-ordered minerals, there is no comprehensive review of the genesis, characteristics and ma...

Abstract Quantitative knowledge of the amount and stability of soil organic matter (SOM) is necessary to understand and predict the role of soils in the global carbon cycle. At present little is known about the influence of soil type on the storage and stability of SOM, especially in the tropics.

Throughout its long history the Earth has undergone warm periods with high atmospheric concentrations of greenhouse gases (GHG), and has responded with different buffering mechanisms whereby atmospheric C has been transferred to other geochemical compartments. Strategies for the mitigation and adaptation to the current climatic forcing may thus be generated by the acceleration of such natural mechanisms, especially those involved in short cycles, mainly in the biosphere and the pedosphere.

Biochar is charcoal made from waste biomass and intended to be added to soil to improve soil function and reduce emissions from the biomass caused by natural degradation to CO2. Nitrogen (N) forms in biochar can be complex and their lability likely to be influenced by pyrolysis temperature which, together with the nature of carbon (C), will influence N mineralisation or immobilisation. These complex relationships are poorly understood, yet impact strongly on the potential agronomic value of bioc...

Abstract Spatial differences in the content of organic carbon in topsoils are closely related to differences in environmental parameters such as climate, land use and geology. The spatial distribution of organic carbon in topsoils in Galicia was predicted using a PLS approach and compared with other more frequently applied regression methods (multiple linear regression, and principal component regression). The accuracy of the estimates has been evaluated using an independent dataset. PLS present...
