Tápanyagszegények

Tápanyagszegények, a Hungarian term, translates to "nutrient-poor" or "low-nutrient" and is commonly used to describe soils, plants, or environments that lack sufficient essential nutrients for optimal growth and development. In the context of soil science, tápanyagszegény soils are characterized by low levels of macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients like iron, manganese, and zinc. These soils often result from natural geological processes, excessive leaching, or intensive agricultural practices that deplete the soil's nutrient reserves without adequate replenishment.

Plants growing in tápanyagszegény conditions may exhibit stunted growth, reduced leaf size, pale foliage (chlorosis), and lower yields. They may also be more susceptible to pests and diseases. To improve the productivity of such soils, farmers and gardeners typically employ strategies like adding organic matter, such as compost or manure, applying synthetic fertilizers, or practicing crop rotation with legumes that can fix atmospheric nitrogen.

The concept of tápanyagszegény can also extend to aquatic ecosystems, where nutrient-poor waters, often referred to as oligotrophic, support low levels of primary productivity. These environments are typically characterized by clear water and a limited abundance of aquatic life.
