Custom Soil Resource Report <br />Mineral soil <br />Soil that is mainly mineral material and low in organic material. Its bulk density is <br />more than that of organic soil. <br />Minimum tillage <br />Only the tillage essential to crop production and prevention of soil damage. <br />Miscellaneous area <br />A kind of map unit that has little or no natural soil and supports little or no <br />vegetation. <br />Miscellaneous water (map symbol) <br />Small, constructed bodies of water that are used for industrial, sanitary, or mining <br />applications and that contain water most of the year. <br />Moderately coarse textured soil <br />Coarse sandy loam, sandy loam, or fine sandy loam. <br />Moderately fine textured soil <br />Clay loam, sandy clay loam, or silty clay loam. <br />Mollic epipedon <br />A thick, dark, humus -rich surface horizon (or horizons) that has high base <br />saturation and pedogenic soil structure. It may include the upper part of the <br />subsoil. <br />Moraine <br />In terms of glacial geology, a mound, ridge, or other topographically distinct <br />accumulation of unsorted, unstratified drift, predominantly till, deposited primarily <br />by the direct action of glacial ice in a variety of landforms. Also, a general term for <br />a landform composed mainly of till (except for kame moraines, which are <br />composed mainly of stratified outwash) that has been deposited by a glacier. <br />Some types of moraines are disintegration, end, ground, kame, lateral, <br />recessional, and terminal. <br />Morphology, soil <br />The physical makeup of the soil, including the texture, structure, porosity, <br />consistence, color, and other physical, mineral, and biological properties of the <br />various horizons, and the thickness and arrangement of those horizons in the soil <br />profile. <br />Mottling, soil <br />Irregular spots of different colors that vary in number and size. Descriptive terms <br />are as follows: abundance —few, common, and many, size —fine, medium, and <br />coarse, and contrast —faint, distinct, and prominent. The size measurements are <br />of the diameter along the greatest dimension. Fine indicates less than 5 <br />millimeters (about 0.2 inch); medium, from 5 to 15 millimeters (about 0.2 to 0.6 <br />inch); and coarse, more than 15 millimeters (about 0.6 inch). <br />41 <br />
