Mineralverfügbarkeit

Mineralverfügbarkeit refers to the extent to which minerals present in soil or feed are accessible and absorbable by plants or animals. It is a critical factor for plant growth and animal health. For plants, mineralverfügbarkeit is influenced by soil properties such as pH, organic matter content, and the presence of other elements that can compete for uptake. For example, a highly acidic soil might make certain minerals less soluble and therefore less available.

In animal nutrition, mineralverfügbarkeit describes how much of a mineral consumed in the diet can actually be absorbed and utilized by the animal's body. This depends on the chemical form of the mineral, the presence of other dietary components that can inhibit or enhance absorption (like phytates or certain vitamins), and the physiological state of the animal. Different sources of the same mineral can have vastly different bioavailability. For instance, inorganic mineral salts may be less available than organic mineral chelates, where the mineral is bound to an amino acid. Understanding mineralverfügbarkeit is essential for formulating balanced diets and ensuring optimal nutrient supply in both agriculture and animal husbandry.
