Document Summary
Some of the earliest written documents were agricultural manuals: many specifically focused on soils, historical studies have revealed close relationships between success of civilizations and soil management. Some of the most common agricultural methods stem directly from knowledge of soil science. Slash and burn agriculture: clear vegetation to temporarily increase soil nutrients. Physical weathering: also referred to as disintegration , main agents of physical weathering, changing temperatures, wind abrasion. Chemical weathering: also referred to as decomposition , main agents of chemical weathering, water. Soil profile: a vertical section of the soil through all of its horizons and extending into rock below. Soil horizon: a layer of soil, approximately parallel to the surface, differing in properties and characteristics from layers above and below it. the. 2 sides * 64cm(cid:1) per side total area = 384cm. 2 per side * cubes total area = 1536 cm.
