They are variously called Terra Rossa (on hard limestone) and Red Mediterranean Soils. Not all soils in a Mediterranean environment are, however, qualified as such because normal pedogenetic development may be hampered by erosion (rejuvenation of the profile), lack of time, and lack of water or unfavorable parent material characteristics. The impact of climate, topography, parent material (mineralogical composition, coherence and permeability), time and human influence as soil forming factors is discussed. Pedogenesis is reviewed and three phases in a color sequence are recognized, ©Encyclopedia of Life Support Systems (EOLSS) LAND USE, LAND COVER AND SOIL SCIENCES – Vol. VII – Mediterranean Soils - Willy Verheye, Diego de la Rosa with a major focus on soils developed over carbonaceous substrata. -

Soil compaction can have a number of negative effects on Compaction of soil is the compression of soil particles into soil quality and crop production including the following: a smaller volume, which reduces the size of pore space available for air and water. Most soils are composed of • causes soil pore spaces to become smaller about 50 per cent solids (sand, silt, clay and organic • reduces water infiltration rate into soil matter) and about 50 per cent pore spaces. • decreases the rate that water will penetrate into the soil root zone and subsoil • increases the potential for surface Compaction concerns water ponding, water runoff, surface soil waterlogging and soil erosion Soil compaction can impair water Soil compaction infiltration into soil, crop emergence, • reduces the ability of a soil to hold root penetration and crop nutrient and can be a serious water and air, which are necessary for water uptake, all of which result in form of soil plant root growth and function depressed crop yield. • reduces crop emergence as a result of soil crusting Human-induced compaction of degradation. • impedes root growth and limits the agricultural soil can be the result of using volume of soil explored by roots tillage equipment during soil cultivation or result from the heavy weight of field equipment. • limits soil exploration by roots and Compacted soils can also be the result of natural soil- decreases the ability of crops to take up nutrients and forming processes. -

Wisconsin Geological and Natural History Survey, Madison, Wisconsin 53705, USA ABSTRACT A paleosol beneath the Upper Cambrian Mount Simon Sandstone in Wisconsin provides an opportunity to evaluate the characteristics of Cambrian weathering in a subtropical climate, having been located at 207S paleolatitude 500 My ago. The 285-cm-thick paleosol resulted from advanced chemical weathering of a gabbroic protolith, recording a total mass loss of 50%. Weathering of hornblende and plagioclase produced a pedogenic assemblage of quartz, chlorite, kaolinite, goethite, and, in the lowest part of the profile, siderite. Despite the paucity of quartz in the protolith and 40% removal of SiO2 from the profile, quartz constitutes 11%–23% of the pedogenic mineral assemblage. Like many other Precambrian and Cambrian paleosols in the Lake Superior region, the paleosol experienced potassium metasomatism, now con- taining 10%–25% mixed-layer illite-vermiculite and 5%–44% potassium feldspar. -
Soil Crusts Structural Soil Crusts Are Relatively Thin, Dense, Somewhat Continuous Layers of Non-Aggregated Soil Particles on the Surface of Tilled and Exposed Soils
Indicator Test Function USDA Natural Resources Conservation Service P F W Soil Quality Indicators Soil Crusts Structural soil crusts are relatively thin, dense, somewhat continuous layers of non-aggregated soil particles on the surface of tilled and exposed soils. Structural crusts develop when a sealed-over soil surface dries out after rainfall or irrigation. Water droplets striking soil aggregates and water flowing across soil breaks aggregates into individual soil particles. Fine soil particles wash, settle into and block surface pores causing the soil surface to seal over and preventing water from soaking into the soil. As the muddy soil surface dries out, it crusts over. Left: Note the surface crust on this soil. The field was in tall fescue sod for 11 years. It was cleared and plowed using conventional Structural crusts range from a few tenths to as thick as two tillage methods. Photo courtesy Bobby Brock, USDA NRCS (retired).

Soils of County Clare
Copyright of Teagasc, The Agriculture and Food Development Authority Soil Survey Bulletin No. 23 Soils of County Clare by T. F. Finch (Report compiled by T. F, Finch, E. Culleton and S. Diamond) National Soil Survey of Ireland An Foras Taluntais (THE AGRICULTURAL INSTITUTE) Published by An Foras Taluntais, 33 Merrion Road, Dublin 4 Price: £1.50 June, 1971 PREFACE This publication, Soil Survey Bulletin No. 23, presents the findings of the Soil Survey of County Clare. It is one of a series of county soil surveys being carried out by the National Soil Survey of An Foras Taluntais (The Agricultural Institute) for the purpose of providing basic information which can be used in optimum land-use planning. The field mapping was carried out at a scale of 1:10,560 (6 in. = 1 mile; 15 cm = 1.6 km) but the detail mapped on the field sheets is not shown on the published soil map at the scale of 1:126,720 (} in. 1 mile: 1.25 cm = 1.6 km) due to scale limitation. Copies of the field maps are available for consultation in the Soil Survey Office at Johnstown Castle, Wexford. Mr. T. F. Finch was responsible for the operation of this survey; he commenced work in the county in 1965 and completed the field investigations in 1968. Technical assistance was provided from time to time by Mr. P. Feeney, Mr. T. O'Shea and Mr. T. Martin. Mr. S. Diamond gave assistance and advice in soil correlation, classification and land-use interpretation, and Mr. R. F. -
