morefootnotes date May 2011 Natural fertility method of birth control is a concept developed by French people French historical demographer Louis Henry to refer to the level of fertility that would prevail in a population that makes no conscious effort to limit, regulate, or control fertility , so that fertility depends only on physiological factors affecting fecundity . In contrast, populations that practice fertility control will have lower than natural fertility levels as a result of delaying first births a lengthened interval between menarche and first pregnancy , spacing out the intervals between births, or stopping child bearing at a certain age. Such control does not assume the use of artificial means of fertility regulation or modern contraceptive methods but can result from the use of traditional means of contraception or pregnancy prevention e.g., coitus interruptus , or from social norms or practices regarding celibacy, the age at marriage and the timing and frequency of sexual intercourse , including periods of prescribed sexual abstinence. Ansley J. Coale Ansley Coale and other demographers have developed several methods for measuring the extent of such fertility control, in which the idea of a natural level of fertility is an essential component.

Soil is made up in part of finely ground rock geology rock particles, grouped according to size as sand , silt and clay . Each size plays a significantly different role. For example, the largest particles, sand, determine aeration and drainage characteristics, while the tiniest, sub microscopic clay particles, are chemically active, binding with water and plant nutrient s. The ratio of these sizes determines soil type clay, loam , clay loam, silt loam, and so on.
