Soils differ widely in their properties because of geologic and climatic variation over distance and time. Transfers of material within the soil, including biological mixing and leaching (minerals dissolved in water moving through soil), contribute to the organization of the soil. Movement of water into soil is called infiltration, and the downward movement of water within the soil is called percolation , permeability or hydraulic conductivity. (tu0115lu2032u0259-pr-tu0101u2032shu0259n) A hypothetical method of transportation in which matter is converted into minute particles or into energy at one point and re-created in original form at another. The solubility of elements, thus, their concentration in the soil solution depend upon the solubility equilibrium. Soil organisms are responsible for the decay and cycling of both macronutrients and micronutrients, and their activity affects the structure, tilth and productivity of the soil. These soil functions include: air quality and composition, temperature regulation, carbon and nutrient cycling, water cycling and quality, natural "waste" (decomposition) treatment and recycling, and habitat for most living things and their food. As soils develop over time, layers (or horizons) form a soil profile. -carrying capacity of the stream, interplay between velocity and discharge. Air: Certain plants also add some inputs to the soil.
