The salt concentration Cp can be taken as a part of the salt concentration of the soil in the unsaturated zone (Cu) giving: Cp = Le.Cu, where Le is the leaching efficiency. The leaching efficiency is often in the order of 0.7 to 0.8, [14] but in poorly structured, heavy clay soils it may be less.
Stratiolaelaps scimitus and the similar species, S. aculiefer are soil-dwelling, predatory mites. Stratiolaelaps mites feed on fungus gnats, springtails, thrips pupae, and other small insects in the soil. The mite is 0.5 mm (1 ⁄ 50 in) long and light-brown in color. It inhabits the top 1 ⁄ 2 inch (13 mm) layer of soil. Both nymphs and ...
Springtails (class Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects.Although the three lineages are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they are to all insects, which have external mouthparts.
Leaching may also refer to the practice of applying a small amount of excess irrigation where the water has a high salt content to avoid salts from building up in the soil (salinity control). Where this is practiced, drainage must also usually be employed, to carry away the excess water.
Soil and surface Collembola (or springtails) Soil mites: Oribatida, Mesostigmata, acariform mites and other small Arachnids; Small centipedes; Small insects and their larvae; Small crustaceans. Many species of microarthropods have not yet been described and require further study. Sizes: from fractions of a millimeter to several millimeters.
Even a springtail drifting on the surface tension of a layer of water often can jump successfully. Furthermore, the furcula is effective in environments typical of Collembola; most predators of springtails are small and many have little power of sight, so if the prey leaps in time, the chances are that from the hunter's point of view, it simply ...
