ravinneseos

Ravinneseos is a term used in Finnish nutrition and agronomy to denote the set of chemical substances required by living organisms to maintain life, growth, and reproduction. It covers both what is supplied in the diet and what is available in the growth medium for plants.

In humans and animals, ravinneseos comprises energy-providing macronutrients – carbohydrates, proteins, fats – as well as micronutrients including vitamins and minerals, dietary fiber, and water. Nutrient requirements vary by age, sex, activity, and health status, and are expressed as guidelines or recommended daily allowances (RDAs).

In plants, ravinneseos refers to essential mineral nutrients. Plants require macroelements nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), and microelements such as iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), chlorine (Cl). The availability is influenced by soil pH and composition; in hydroponic systems, nutrient solutions are formulated to meet these needs at controlled concentrations.

Assessment and management: In human nutrition, dietary assessment uses food composition databases to estimate intake. In agriculture, soil tests and plant tissue analyses guide fertilization; hydroponics uses electrical conductivity (EC) and pH control to manage ravinneseos.

Ravinneseos is central to discussions of diet quality, food labeling, and agricultural sustainability.
