Fertilite

Fertilite is the capacity to reproduce or to sustain productive growth, depending on context. In biology, human and animal fertilite refers to the ability to conceive and carry a pregnancy to term. In agriculture and ecology, soil fertilite describes the soil's capacity to supply essential nutrients to plants and to maintain productive ecosystems.

For human fertilite, factors include age, health, hormonal balance, nutrition, body mass, exposure to toxins, chronic diseases, and access to healthcare and contraception. Fertilite can be affected by diseases such as endometriosis, polycystic ovary syndrome, or male factor infertility. Treatments such as assisted reproductive technologies (ART) can enable conception for some couples.

Measurement of human fertilite uses fertility rate metrics. The total fertility rate estimates the average number of children a woman would bear over her lifetime under current age-specific rates; birth rates reflect births per 1,000 population. Fertilite patterns vary widely by region and over time, influenced by economics, education, gender roles, culture, and policy.

Regarding soil fertilite: the capacity of soil to provide nutrients, water, and favorable conditions for plant growth. It depends on soil texture, structure, organic matter, microbial activity, pH, and nutrient availability (primary nutrients N, P, K and micronutrients). Management practices such as crop rotation, composting, mineral fertilization, liming, and conservation tillage affect soil fertility and sustainability.
