Plodnost zen v oblastech CSR 1961-1976. (Woman's fertility in regions of the Czech Socialist Republic in 1961-1976)
The fertility of women is observed in regions and districts and valuated its dynamics by specific indicators. Results prove that besides oscillating the typical trend is rapprochement of reproductive behaviour of women in the whole Czech territory
. The level of woman's fertility in Prague remains one of the problems of population practice.
Woman's fertility in Czechoslovakia during 1970-1979
Favourable population climate has lasted. Both absolute number of delivered children and reproduction rate have declived but in very slow way. The total fertility rate (2,328) and the net reprodcution rate (1,108) belonged to the most favourable
Marriage markets and nonmarital fertility in the United States
Age group ; Demographic behaviour ; Demography ; Family ; Fertility ; Marriage ; Matrimonial status ; Nuptiality ; United States
The AA. examine the effect of women's marriage opportunities on nonmarital fertility rates and ratios across 75 U.S. metropolitan areas. They measure the quantity and « quality » of marriageable men simultaneously specific for women's age, race
, education and place of residence. Only a small proportion of the racial difference in nonmarital fertility appears attributable to differences in the marriage markets of black and of white women.

Analyse comparative des concepts de milieu fertile et de sol. Il est important d'élucider les rapports entre ces concepts dans la relation avec le rôle croissant du facteur anthropique sur la Terre et d'établir une modélisation mathématique des sols
. Propose de diviser la multitude des milieux fertiles en deux sous-multitudes : les sols proprement dits et les vagel (de Van Gel'mont). - (D'après l'Ed.).
The A. examines the mutual relations of religion, ethnicity and fertility in the territory of the former Hungarian Kingdom at the beginning of the 20th century. This period is interesting for the fact that fertility rate in Hungary decreased
Relationship of the geomorphological position, genetic, physical, chemical and mineralogical features of sand soils with their fertility in Lithology and stratigraphy of loess and paleosols.
The sand soils of the cooperative farm under investigation can be classified as follows: 1. Soils of high fertility, a. multi-layer humous sand soils, b. sandy chernozem meadow soils| 2. Soils of medium fertility, humous sands| 3. Soils of low
fertility, a. blown sand soils, b. sand mantle soils. (DLO).
Prispevek k vyvoji plodnosti v ceskych zenich. (Contribution to development of fertility in Czech countries)
The study analyses the development at the end of the 19th century and in the first half of the 20th century which was characterised with significant decline of fertility under growing nuptiality. A fundamental occurred around 1900 when almost in all
regions the level of fertility began to decline sharply. Fertility decline was finished in principle before the end of the World War II. (MS).
Economic value of children and fertility preferences in a fishing community in Ghana
This article examines the fertility preferences of men and women living at Akplabanya, a fishing community in Ghana. The findings of the study show that demand for labour, expectations of long term security, and gendered power relations have
contributed to high fertility levels and preferences in the study area. It has been concluded that significant fertility decline in the area will only occur when fertility preferences of men have changed. Family planning programmes must therefore target both
men and women. Improving economic status of women will also go a long way to bring about fertility transition in rural communities in Ghana.
Soil fertility in a large dryland floodplain : patterns, processes and the implications of water resource development
The aim of this paper is to determine the effect of flooding on soil fertility. To do this, the AA. examine spatial patterns in soil N, P and carbon (C) across the floodplain. The AA. use the data and a literature review to generate hypotheses
for the dominant processes affecting soil soil fertility on the floodplain and, by extension, the effects on fertility of changes in flood frequency. A better understanding of the effects of flooding on soil fertility and floodplain productivity should improve
Uzemni diferenciace plodnosti zen v Ceskoslovensku a jeji zmeny v prubehu sedmdesatych let. (Territorial differenciation of female fertility in Czechoslovakia and its changes during the seventies)
The work presents the regional female fertility during the seventies by help of districts indicators uncharged with differences of age structure. Female fertility of Slovakia has significantly approached to the level of Czech districts. In the areas
with typical high rates in the past, the process of fertility decline has run faster and some positive reactions on pronatalist measures were not there so important as in the territories with lower fertility. (MS).
A talajok termékenységét gatlo tényezok Magyarorszagon. (Limiting factors of soil fertility in Hungary)
Among limiting factors of soil fertility the A. mentions among others the extremely light texture, acidity, salinity-alkalinity, salinity-alkalinity in the deeper soil layers, extremely heavy texture, water-logging, erosion, solid rock near
