Ravinteellisyys

Ravinteellisyys refers to the nutrient content of something, most commonly used in the context of food and soil. In food, ravinteellisyys indicates the presence and amount of essential nutrients like vitamins, minerals, proteins, carbohydrates, and fats. A food with high ravinteellisyys is considered nutritious, providing a significant amount of beneficial compounds for the body's functioning and health. Conversely, foods with low ravinteellisyys may be high in calories but lack essential nutrients, often referred to as "empty calories."

In agriculture and horticulture, ravinteellisyys describes the availability of nutrients in the soil for plant uptake. Healthy soil with high ravinteellisyys supports robust plant growth and development. Soil ravinteellisyys is influenced by factors such as organic matter content, pH level, and the presence of essential mineral elements. Soil testing is often performed to assess its ravinteellisyys and determine if fertilization is necessary to supplement or balance nutrient levels for optimal crop yields or plant health. The concept emphasizes the importance of nutrient availability for biological systems.
