GEOG M107 Midterm: Geog M107 Midterm Study Guide
Document Summary
Some land is suited for intensive cropping (where soil is deep, level, fertile, well drained, and has favorable texture & structure) Land that is steep, shallow, stony: suitable only for wildlife or other non- disruptive uses: vegetative practices: provide denser plant cover for a larger % of time. Terrace systems: erosion control by holding soil in the field: soil movement may occur between terraces, but soil caught in terrace channels will not pollute a stream. I. e. people downstream: people practice traditions and are resistant to change, developing countries: survival is priority over changing traditional practices, short-term tenancy (or small farming tracts) precludes tenants from investing in long-term benefits. Any runoff that occurs is slower and carries less soil. Anything that slows runoff & helps get more water into soil/keeps water in soil by reducing evaporation (cid:314) provides more water for plant growth. Improved plant growth (cid:314) reduce wind erosion & water erosion.
