Abstract:

Since ancient times, peasants have relied on the presence of some plants or animals to assess soi’s fertility. This study carried out in Dogo site in Niger and that aim is ti determine the main farmer indicators of soil fertility assessment. For this, an individual semi-structured questionnaire was administered to the farmers. Results showed that several types of biological indicators are used by farmers to assess soil’s fertility through the presence or absence of some plants and/or animals. Thus, Cenchrus biflorus, Cyperus alopeuroides, Alysicarpus ovalifolius, Brachiaria spp have been cited

Abstract:

We introduce the two-sex net reproduction rate (2SNRR) and the two-sex total fertility rate (2STFR)—two demographic indicators that reflect the number of children born, given age specific fertility and mortality of the adults. The main quality of these indicators is that they measure the childbearing behaviour of both women and men. The indicators have intuitive value, since they tell us to what extent adults are replaced by children. While the traditional net reproduction rate (NRR) describes general replacement trends among women only, the 2SNRR is an indicator of a population’s growth poten

Abstract:

The need to search for integral indicators of soil fertility for monitoring based on the control of the synthesis of total biomass (the organic substance underlying the law of soil fertility) and crop productivity using modern information (primarily unmanned technologies) is justified in order to obtain detailed information on soil fertility occupied by crops. At the same time, it is important to develop methods for monitoring the balance of organic matter of the soil, reflecting its mineralization, humification and other types of its transformation.

Abstract:

The distribution of soil nutrients in cultivated land was clarified and the soil fertility was systematically evaluated and analyzed. First, five important indicators that have a greater impact on soil comprehensive fertility were selected, and the index data were standardized. According to the different impacts of each indicator on soil fertility, the average value of partial correlation coefficient between each indicator and other indicators was calculated, and a certain weight was given to each indicator. The inverse absolute value method was used to construct a fuzzy similarity matrix, and

Analysis of the number of women of active reproductive age, total fertility rate, life expectancy, and gender-specific mortality rates are important steps in this direction.

Current trends in fertility are similar in most countries of the world. To reduce the level of fertility, actively manifested since the second half of the last century, important changes in the calendar of births were added. The classical indicators of demographic statistics are more often dealing with the intensity of fertility, to a lesser extent — with the timing of fertility. The authors made an attempt to compile a system of indicators for the timing, which was then used to study the stages and types of ageing of fertility.

However, in many fertilization recommendation contexts, farmers mainly fertilize according to classified fertility indicators, rather than by continuous soil property values.

Abstract:

The main indicators of soil fertility based on the results of an agrochemical survey of agricultural lands in Chernivtsi region in the XI round (2016–2020) are given. It was established that the acidity of the soil solution in the region is dominated by lands close to neutral (31.8%) and neutral (36.5%). The weighted average indicator of saline pH is 5.8, which corresponds to a close to neutral reaction of the soil solution. According to the level of humus provision, soils with an average humus content prevail (66.7%), and the weighted average humus content in the region is 2.7%. According to

The topic of the article is to study the factor of financial accessibility of residential construction on fertility and migration rates in rural areas. The article analyzes the impact of financial opportunities to purchase housing in rural areas on the demographic indicators of rural areas. At the same time, the indicator of housing affordability in rural areas is defined as the ratio of the cost per square meter of housing (individual residential buildings) and the wages of economically active citizens employed in agriculture, minus the subsistence minimum.

AbstractThe longstanding issue of declining fertility in developed nations motivates a revaluation of the effectiveness of fertility‐targeted policies. This thesis focuses on the 2004 Australian Baby Bonus, a past pronatalist incentive offering a lump sum financial transfer for every child born after 1 July 2004. We employ the synthetic control method to construct a counterfactual scenario for Australia in the absence of the policy's introduction. Using aggregate country‐level data from the World Bank World Indicator's Database from 1998 to 2012, we carefully select suitable Organisation for E

Soil health assessment can be a critical soil testing tool that includes biological and physical indicators of soil function related to crop and environmental health. Soil health indicator minimum data sets should be regional and management goal specific. The objective of this study was to initiate the steps to develop a soil assessment tool for irrigated orchard soils in Central Washington, United States including defining objectives, gathering baseline data and selecting target indicators.

The article discusses the possibility of using artificial intelligence and machine learning methods to predict soil fertility based on remote sensing data. The research object was 70 soil samples taken in the village of Vshchizh, Bryansk region. Multispectral imaging of the earth's surface from the Sentinel-2 satellite was also used to assess the soil condition. The study in this article is based on the indicators of humus (%), P2O5 (mg/kg), and K2O (mg/kg). The prediction is done using a neural network model based on the Rosenblatt perceptron.

Recently, the reforms in the direction of increasing manufacture of the agricultural products, ensuring food safety have given their positive results. There are some opportunities to produce material goods, to ensure economical development, to raise people’s standard of living in the country. As it is known, Azerbaijan possesses natural underground and surface resources. But the soil and water supplies are quite limited. Lately, some difficulties have been created in provision of agricultural plants with irrigated water.It should be noted that, one of the factors negatively affecting the agric

Aiming at agricultural production in a sustainable, satisfactory manner and with less impact on the environment, cultivation systems such as crop-livestock integration, crop-livestock-forest integration, direct planting systems and agroforestry have been adopted. Crop-Livestock-Forest Integration Systems allow the increase in agricultural production without the need to convert new areas to agriculture, increasing the diversification of agricultural production on rural properties and applying different scales of agricultural enterprises. Thus, crop-livestock-forest integration systems are an im

Abstract:

The purpose of the work is to analyze the dynamics of soil fertility indicators under forest belts in comparison with the inter-belt space in the agricultural landscape due to soil transformation under the influence of adaptive landscape farming systems. A comparative analysis of the variability of soil fertility indicators in forest belts and agrocenoses revealed similar trends in its direction and intensity, which indicates the uniform nature of the soil-forming process. However, some features have been identified. The humus content in the soils of forest belts is on average slightly higher

The fruiting indicators (berry setting, average berry weight, average number of seeds per berry) in case of most self-pollinating highbush blueberry varieties, as a rule, are lower than with natural cross-pollination. In accordance with the average indicators of fruit set during self-pollination of flowers, blueberry varieties are ranked into five groups corresponding to the degree of self-fertility.

Some studies show the impact of financial inclusion on different developmental outcomes, such as poverty, inequality, education, health, empowerment and economic growth and development. However, only a few studies have analysed the impact of financial inclusion on specific health indicators. Financial inclusion has a significant impact on fertility decline.
