The physical properties of a soil largely determine the manner in which it can be used. Properties, e.g. the water holding capacity, permeability to water, aeration, plasticity and nutrient-supplying ability, are influenced by the size, proportion, arrangement and mineral compositon of the soil particles. The proporton of the four major components of the soils--inorganic or mineral particles, organic material, water and air--vary greatly from place to place and with depth. The amount of water air in a soil fluctuates from season to season, but the proportion of primary solid components of the soil, however remains unchanged. |
