Water pools on the surface and leaves behind rings of salt when it evaporates. Because salts are water-soluble, they can enter into soil environments through groundwater, flooding, or irrigation.2 Salts may accumulate in soil for a variety of reasons, all of which relate to some disruption in water and water-soluble salt dynamics. Pay.-NorthStarSupplies. In this case, the soil has a higher osmotic potential than the plant root because water molecules are attracted to the soil's salt. Yale University, Master of Divinity, Theology. Shallow-rooted plants may not reach subsoil moisture, and extra subsoil moisture may induce salinity. Soil salinization occurs naturally in arid climates, but irrigation increases the rate at which salts can accumulate in the topsoil. Form of agriculture that uses mechanical goods such as machinery, tools, vehicles and facilities to produce large amounts of agricultural goods; a process requiring very little human labor. Soil salinization can be prevented by implementing drainage systems that allow for excess salts to be leached out of the soil. What is the perichondrium? Cao, Yiqin et al. (2000). SUSTAINABLE AGRICULTURE: farming methods that are profitable, environmentally sound and good for communities. Soil salinization is most prevalent in arid and semi-arid climates because evaporation exceeds precipitation. SLASH & BURN (shifting cultivation): clearing an area in a tropical forest for planting by burning the vegetation. It is also suggested to enhance the sensing methods besides retrieval systems to facilitate direct detection of salinization and waterlogging parameters at large-scales. AP Human Geography Unit 5 Vocabulary Flashcards | Quizlet Degradation of land, especially in semiarid areas, primarily because of human actions like excessive crop planting, animal grazing, and tree cutting. Reduce evaporation with mulch or crop residue. Plants use many minerals found in salts, including magnesium, phosphorus, sulfur, and more. Remove only the dimes when they land heads-up. A recent FAO estimate reported that a large portion of total global soil resources are degraded and this problem is persistently expanding.
